4f92bab41b ARM: OMAP: DRA7: CM: Add minimal regbit shifts
This header contains minimal regbits that are currently used in code.
This header has traditionally been autogenerated on OMAP4+ devices but
the autogenerated contents are largely (95%) unused and hence to reduce
unsued data in the kernel this header has been cut down (from the autogen
output) to whatever is currently needed. This is done by running a cleanup
script on top of the existing autogen script.

A handful of fixes for 3.11 are still trickling in. These are:
 - A couple of fixes for older OMAP platforms
 - Another few fixes for at91 (lateish due to European summer vacations)
 - A late-found problem with USB on Tegra, fix is to keep VBUS regulator
   on at all times
 - One fix for Exynos 5440 dealing with CPU detection
 - One MAINTAINERS update

42c604ba7c ARM: OMAP2+: fix wrong address when loading PRM_FRAC_INCREMENTOR_DENUMERATOR_RELOAD
The denominator should be load from INCREMENTOR_DENUMERATOR_RELOAD_OFFSET
rather than INCREMENTER_NUMERATOR_OFFSET.

This is more likely a typo, since INCREMENTER_DENUMERATOR_RELOAD[23:17] is
reserved. It seems that it won't make much trouble without this fix, because
the useful [11:0] bits are mask and set the right value. Anyway, reading
from a right address is better choice.

dropped a config symbol that was unused by the musb core, but it turns
out that board support code still had references to it.

As the core now handles both dual role and host-only modes, we can just
pass MUSB_OTG as mode from board files.

311b79bb7e Removal of unused omap defines via Paul Walmsley <paul@pwsan.com>:
This series removes the currently-unused PRCM macros from
 arch/arm/mach-omap2.
 
 Basic test logs are available at:
 
 http://www.pwsan.com/omap/testlogs/drop_unused_prcm_macros_v3.11-rc/20130721211401/
 
 Once, years ago, we thought that it would be good to document the PRCM
 register bits in the Linux codebase.  Most folks in the broader
 community did not have access to the same documentation, so we thought
 that they might be able to use these bits to fix bugs and improve the
 code.
 
 We were also able to autogenerate most of these macros, so it was
 thought that defining them in advance would reduce the risk of error,
 inconsistencies, and merge conflicts caused when patch sets
 incrementally defined them by hand.
 
 Well, nice thoughts.  But the first rationale was rendered partially
 obsolete when TI started to release public TRM documentation PDFs at
 some point in the OMAP3 timeframe.  (Despite their weaknesses, TI's
 public OMAP TRMs remain the most useful public documentation available
 for any ARM Linux SoC -- at least to the extent of my knowledge.)  And
 then the current Linux development tropism towards
 development-by-negative-diffstat obliterated the remainder of the
 above two philosophies.
 
 So, for the few, the masochistic, out there who wish to continue
 developing TI PRCM code, I would ask that you resurrect any
 additionally-needed macros from these commits, rather than writing
 them manually.  Purely for the sake of a pleasant atavism, perhaps; the
 way one appreciates a used bookstore, or a video rental store...
 
 And thanks to the upstream maintainers for being patient while we
 adjust.

Merge tag 'omap-for-v3.12/cleanup-unused-defines' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/cleanup

From Tony Lindgren:
Removal of unused omap defines via Paul Walmsley <paul@pwsan.com>:

This series removes the currently-unused PRCM macros from
arch/arm/mach-omap2.

Basic test logs are available at:

http://www.pwsan.com/omap/testlogs/drop_unused_prcm_macros_v3.11-rc/20130721211401/

Once, years ago, we thought that it would be good to document the PRCM
register bits in the Linux codebase.  Most folks in the broader
community did not have access to the same documentation, so we thought
that they might be able to use these bits to fix bugs and improve the
code.

We were also able to autogenerate most of these macros, so it was
thought that defining them in advance would reduce the risk of error,
inconsistencies, and merge conflicts caused when patch sets
incrementally defined them by hand.

Well, nice thoughts.  But the first rationale was rendered partially
obsolete when TI started to release public TRM documentation PDFs at
some point in the OMAP3 timeframe.  (Despite their weaknesses, TI's
public OMAP TRMs remain the most useful public documentation available
for any ARM Linux SoC -- at least to the extent of my knowledge.)  And
then the current Linux development tropism towards
development-by-negative-diffstat obliterated the remainder of the
above two philosophies.

So, for the few, the masochistic, out there who wish to continue
developing TI PRCM code, I would ask that you resurrect any
additionally-needed macros from these commits, rather than writing
them manually.  Purely for the sake of a pleasant atavism, perhaps; the
way one appreciates a used bookstore, or a video rental store...

And thanks to the upstream maintainers for being patient while we
adjust.

However, with DT, the bus number is 2. As we now only have DT boot for

With commit '82702ea11ddfe0e43382e1fa5b66d807d8114916' "ARM: OMAP2+:
Fix serial init for device tree based booting" stubbing out
omap_serial_early_init() for Device tree based booting, there was a
crash observed on AM335x based devices when hwmod does a
_setup_reset() early at boot.

This was rootcaused to hwmod trying to reset console uart while
earlycon was using it.  The way to tell hwmod not to do this is to
specify the HWMOD_INIT_NO_RESET flag, which were infact set by the
omap_serial_early_init() function by parsing the cmdline to identify
the console device.

Parsing the cmdline to identify the uart used by earlycon itself seems
broken as there is nothing preventing earlycon to use a different one.

This patch, instead, attempts to populate the requiste flags for hwmod
based on the CONFIG_DEBUG_OMAPxUARTy FLAGS. This gets rid of the need
for cmdline parsing in the DT as well as non-DT cases to identify the
uart used by earlycon.

8bd26e3a7e arm: delete __cpuinit/__CPUINIT usage from all ARM users
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit  -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings.  In any case, they are temporary and harmless.

This removes all the ARM uses of the __cpuinit macros from C code,
and all __CPUINIT from assembly code.  It also had two ".previous"
section statements that were paired off against __CPUINIT
(aka .section ".cpuinit.text") that also get removed here.

Pull timer core updates from Thomas Gleixner:
 "The timer changes contain:

   - posix timer code consolidation and fixes for odd corner cases

   - sched_clock implementation moved from ARM to core code to avoid
     duplication by other architectures

   - alarm timer updates

   - clocksource and clockevents unregistration facilities

   - clocksource/events support for new hardware

   - precise nanoseconds RTC readout (Xen feature)

   - generic support for Xen suspend/resume oddities

   - the usual lot of fixes and cleanups all over the place

  The parts which touch other areas (ARM/XEN) have been coordinated with
  the relevant maintainers.  Though this results in an handful of
  trivial to solve merge conflicts, which we preferred over nasty cross
  tree merge dependencies.

  The patches which have been committed in the last few days are bug
  fixes plus the posix timer lot.  The latter was in akpms queue and
  next for quite some time; they just got forgotten and Frederic
  collected them last minute."

Merge tag 'pm+acpi-3.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management and ACPI updates from Rafael Wysocki:
 "This time the total number of ACPI commits is slightly greater than
  the number of cpufreq commits, but Viresh Kumar (who works on cpufreq)
  remains the most active patch submitter.

  To me, the most significant change is the addition of offline/online
  device operations to the driver core (with the Greg's blessing) and
  the related modifications of the ACPI core hotplug code.  Next are the
  freezer updates from Colin Cross that should make the freezing of
  tasks a bit less heavy weight.

  We also have a couple of regression fixes, a number of fixes for
  issues that have not been identified as regressions, two new drivers
  and a bunch of cleanups all over.

  Highlights:

   - Hotplug changes to support graceful hot-removal failures.

     It sometimes is necessary to fail device hot-removal operations
     gracefully if they cannot be carried out completely.  For example,
     if memory from a memory module being hot-removed has been allocated
     for the kernel's own use and cannot be moved elsewhere, it's
     desirable to fail the hot-removal operation in a graceful way
     rather than to crash the kernel, but currenty a success or a kernel
     crash are the only possible outcomes of an attempted memory
     hot-removal.  Needless to say, that is not a very attractive
     alternative and it had to be addressed.

     However, in order to make it work for memory, I first had to make
     it work for CPUs and for this purpose I needed to modify the ACPI
     processor driver.  It's been split into two parts, a resident one
     handling the low-level initialization/cleanup and a modular one
     playing the actual driver's role (but it binds to the CPU system
     device objects rather than to the ACPI device objects representing
     processors).  That's been sort of like a live brain surgery on a
     patient who's riding a bike.

     So this is a little scary, but since we found and fixed a couple of
     regressions it caused to happen during the early linux-next testing
     (a month ago), nobody has complained.

     As a bonus we remove some duplicated ACPI hotplug code, because the
     ACPI-based CPU hotplug is now going to use the common ACPI hotplug
     code.

   - Lighter weight freezing of tasks.

     These changes from Colin Cross and Mandeep Singh Baines are
     targeted at making the freezing of tasks a bit less heavy weight
     operation.  They reduce the number of tasks woken up every time
     during the freezing, by using the observation that the freezer
     simply doesn't need to wake up some of them and wait for them all
     to call refrigerator().  The time needed for the freezer to decide
     to report a failure is reduced too.

     Also reintroduced is the check causing a lockdep warining to
     trigger when try_to_freeze() is called with locks held (which is
     generally unsafe and shouldn't happen).

   - cpufreq updates

     First off, a commit from Srivatsa S Bhat fixes a resume regression
     introduced during the 3.10 cycle causing some cpufreq sysfs
     attributes to return wrong values to user space after resume.  The
     fix is kind of fresh, but also it's pretty obvious once Srivatsa
     has identified the root cause.

     Second, we have a new freqdomain_cpus sysfs attribute for the
     acpi-cpufreq driver to provide information previously available via
     related_cpus.  From Lan Tianyu.

     Finally, we fix a number of issues, mostly related to the
     CPUFREQ_POSTCHANGE notifier and cpufreq Kconfig options and clean
     up some code.  The majority of changes from Viresh Kumar with bits
     from Jacob Shin, Heiko Stübner, Xiaoguang Chen, Ezequiel Garcia,
     Arnd Bergmann, and Tang Yuantian.

   - ACPICA update

     A usual bunch of updates from the ACPICA upstream.

     During the 3.4 cycle we introduced support for ACPI 5 extended
     sleep registers, but they are only supposed to be used if the
     HW-reduced mode bit is set in the FADT flags and the code attempted
     to use them without checking that bit.  That caused suspend/resume
     regressions to happen on some systems.  Fix from Lv Zheng causes
     those registers to be used only if the HW-reduced mode bit is set.

     Apart from this some other ACPICA bugs are fixed and code cleanups
     are made by Bob Moore, Tomasz Nowicki, Lv Zheng, Chao Guan, and
     Zhang Rui.

   - cpuidle updates

     New driver for Xilinx Zynq processors is added by Michal Simek.

     Multidriver support simplification, addition of some missing
     kerneldoc comments and Kconfig-related fixes come from Daniel
     Lezcano.

   - ACPI power management updates

     Changes to make suspend/resume work correctly in Xen guests from
     Konrad Rzeszutek Wilk, sparse warning fix from Fengguang Wu and
     cleanups and fixes of the ACPI device power state selection
     routine.

   - ACPI documentation updates

     Some previously missing pieces of ACPI documentation are added by
     Lv Zheng and Aaron Lu (hopefully, that will help people to
     uderstand how the ACPI subsystem works) and one outdated doc is
     updated by Hanjun Guo.

   - Assorted ACPI updates

     We finally nailed down the IA-64 issue that was the reason for
     reverting commit 9f29ab11dd ("ACPI / scan: do not match drivers
     against objects having scan handlers"), so we can fix it and move
     the ACPI scan handler check added to the ACPI video driver back to
     the core.

     A mechanism for adding CMOS RTC address space handlers is
     introduced by Lan Tianyu to allow some EC-related breakage to be
     fixed on some systems.

     A spec-compliant implementation of acpi_os_get_timer() is added by
     Mika Westerberg.

     The evaluation of _STA is added to do_acpi_find_child() to avoid
     situations in which a pointer to a disabled device object is
     returned instead of an enabled one with the same _ADR value.  From
     Jeff Wu.

     Intel BayTrail PCH (Platform Controller Hub) support is added to
     the ACPI driver for Intel Low-Power Subsystems (LPSS) and that
     driver is modified to work around a couple of known BIOS issues.
     Changes from Mika Westerberg and Heikki Krogerus.

     The EC driver is fixed by Vasiliy Kulikov to use get_user() and
     put_user() instead of dereferencing user space pointers blindly.

     Code cleanups are made by Bjorn Helgaas, Nicholas Mazzuca and Toshi
     Kani.

   - Assorted power management updates

     The "runtime idle" helper routine is changed to take the return
     values of the callbacks executed by it into account and to call
     rpm_suspend() if they return 0, which allows us to reduce the
     overall code bloat a bit (by dropping some code that's not
     necessary any more after that modification).

     The runtime PM documentation is updated by Alan Stern (to reflect
     the "runtime idle" behavior change).

     New trace points for PM QoS are added by Sahara
     (<keun-o.park@windriver.com>).

     PM QoS documentation is updated by Lan Tianyu.

     Code cleanups are made and minor issues are addressed by Bernie
     Thompson, Bjorn Helgaas, Julius Werner, and Shuah Khan.

   - devfreq updates

     New driver for the Exynos5-bus device from Abhilash Kesavan.

     Minor cleanups, fixes and MAINTAINERS update from MyungJoo Ham,
     Abhilash Kesavan, Paul Bolle, Rajagopal Venkat, and Wei Yongjun.

   - OMAP power management updates

     Adaptive Voltage Scaling (AVS) SmartReflex voltage control driver
     updates from Andrii Tseglytskyi and Nishanth Menon."

fb2af0020a Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
 "This contains the usual updates from other people (listed below) and
  the usual random muddle of miscellaneous ARM updates which cover some
  low priority bug fixes and performance improvements.

  I've started to put the pull request wording into the merge commits,
  which are:

   - NoMMU stuff:

     This includes the following series sent earlier to the list:
      - nommu-fixes
      - R7 Support
      - MPU support

     I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
     were discussing today until we've reached a conclusion/that's had
     some more review.

     This is rebased (and re-tested) on your devel-stable branch because
     otherwise there were going to be conflicts with Uwe's V7M work now
     that you've merged that.  I've included the fix for limiting MPU to
     CPU_V7.

   - Huge page support

     These changes bring both HugeTLB support and Transparent HugePage
     (THP) support to ARM.  Only long descriptors (LPAE) are supported
     in this series.

     The code has been tested on an Arndale board (Exynos 5250).

   - LPAE updates

     Please pull these miscellaneous LPAE fixes I've been collecting for
     a while now for 3.11.  They've been tested and reviewed by quite a
     few people, and most of the patches are pretty trivial.  -- Will Deacon.

   - arch_timer cleanups

     Please pull these arch_timer cleanups I've been holding onto for a
     while.  They're the same as my last posting, but have been rebased
     to v3.10-rc3.

   - mpidr linearisation (multiprocessor id register - identifies which
     CPU number we are in the system)

     This patch series that implements MPIDR linearization through a
     simple hashing algorithm and updates current cpu_{suspend}/{resume}
     code to use the newly created hash structures to retrieve context
     pointers.  It represents a stepping stone for the implementation of
     power management code on forthcoming multi-cluster ARM systems.

     It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
     OMAP4 and Tegra, with processors hitting low-power states requiring
     warm-boot resume through the cpu_resume code path"

0bf6a210a4 ARM SoC driver specific changes
These changes are all driver specific and cross over between arm-soc
 contents and some other subsystem, in these cases cpufreq, crypto,
 dma, pinctrl, mailbox and usb, and the subsystem owners agreed to
 have these changes merged through arm-soc. As we proceed to untangle
 the dependencies between platform code and driver code, the amount of
 changes in this category is fortunately shrinking, for 3.11 we have
 16 branches here and 101 non-merge changesets, the majority of which
 are for the stedma40 dma engine driver used in the ux500 platform.
 Cleaning up that code touches multiple subsystems, but gets rid
 of the dependency in the end.
 
 The mailbox code moved out from mach-omap2 to drivers/mailbox
 is an intermediate step and is still omap specific at the moment.
 Patches exist to generalize the subsystem and add other drivers
 with the same API, but those did not make it for 3.11.
 
 Conflicts:
 * In cpu-db8500.c results from the removal of the u8500_of_init_devices
   function in combination with the split of u8500_auxdata_lookup.
 
 * In arch/arm/mach-omap2/devices.c, the includes got reshuffled.
   we need to keep linux/wl12xx.h and linux/platform_data/mailbox-omap.h.

ee1a8d402e ARM SoC device tree changes
These changes from 30 individual branches for the most part update device
 tree files, but there are also a few source code changes that have crept
 in this time, usually in order to atomically move over a driver from
 using hardcoded data to DT probing.
 
 A number of platforms change their DT files to use the C preprocessor,
 which is causing a bit of churn, but that is hopefully only this once.
 
 There are a few conflicts with the other branches unfortunately:
 
 * in exynos5440.dtsi and kirkwood-6281.dtsi, device nodes are added
   from multiple branches. Need to be careful to have the right
   set of closing braces as git gets this one wrong.
 
 * In kirkwood.dtsi, one 'ranges' line got split into two lines, while
   another line got added. Order of the lines does not matter.
 
 * in sama5d3.dtsi, some cleanup was merged the wrong way, causing
   a bogus conflict. We want the 'dmas' and 'dma-names' properties
   to get added here.
 
 * Two lines got removed independently in arch/arm/mach-mxs/mach-mxs.c
 
 * Contents get added independently in arch/arm/mach-omap2/cclock33xx_data.c

40e71e7015 ARM SoC board specific changes
These are 18 branches on 9 platforms with board specific changes, mostly
 for defconfig files, but nothing really exciting in here.
 
 Since the shmobile platform still uses board files for some of the newer
 machines, we get a few changes there as the result of drivers getting
 enabled for those boards. This causes some conflicts with contents getting
 added from multiple branches in sh-mobile specific files. Renesas is
 putting a lot of work into migrating to device-tree based setup, which
 will make all those files obsolete in the future and avoid both the
 conflicts and the need to have these files in the first place.

3883cbb6c1 ARM SoC specific changes
These changes are all to SoC-specific code, a total of 33 branches on
 17 platforms were pulled into this. Like last time, Renesas sh-mobile
 is now the platform with the most changes, followed by OMAP and EXYNOS.
 
 Two new platforms, TI Keystone and Rockchips RK3xxx are added in
 this branch, both containing almost no platform specific code at all,
 since they are using generic subsystem interfaces for clocks, pinctrl,
 interrupts etc. The device drivers are getting merged through the
 respective subsystem maintainer trees.
 
 One more SoC (u300) is now multiplatform capable and several others
 (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
 towards that goal with this series but need more work.
 
 Also noteworthy is the work on PCI here, which is traditionally part of
 the SoC specific code. With the changes done by Thomas Petazzoni, we can
 now more easily have PCI host controller drivers as loadable modules and
 keep them separate from the platform code in drivers/pci/host. This has
 already led to the discovery that three platforms (exynos, spear and imx)
 are actually using an identical PCIe host controller and will be able
 to share a driver once support for spear and imx is added.
 
 Conflicts:
 * asm/glue-proc.h has one CPU type getting added that conflicts
   with another addition in 3.10-rc7
 * Simple context changes in arch/arm/Makefile and arch/arm/Kconfig

  they are using generic subsystem interfaces for clocks, pinctrl,
  interrupts etc.  The device drivers are getting merged through the
  respective subsystem maintainer trees.

  One more SoC (u300) is now multiplatform capable and several others
  (shmobile, exynos, msm, integrator, kirkwood, clps711x) are moving
  towards that goal with this series but need more work.

  Also noteworthy is the work on PCI here, which is traditionally part
  of the SoC specific code.  With the changes done by Thomas Petazzoni,
  we can now more easily have PCI host controller drivers as loadable
  modules and keep them separate from the platform code in
  drivers/pci/host.  This has already led to the discovery that three
  platforms (exynos, spear and imx) are actually using an identical PCIe
  host controller and will be able to share a driver once support for
  spear and imx is added."

d2033f2c1d ARM SoC cleanups
This contains cleanups as preparation for other branches adding new
 features, we pulled 16 branches for 9 platforms into this one.
 
 Most notable here is the removal of support for ATAGS based OMAP4
 systems. Since all OMAP4 machines are fully functional with DT based
 booting in 3.10, we can remove a lot of code here.
 
 Also noteworthy is Maxime Ripard's cleanup of the machine descriptors,
 which means we need no machine descriptors in a lot more cases and
 can boot additional machines by just having the respective device
 drivers enabled.

2ac524f151 ARM: OMAP5: voltagedomain data: remove temporary OMAP4 voltage data
commit 20d49e9ccf
(ARM: OMAP5: voltagedomain data: Add OMAP5 voltage domain data)

Introduced dummy volt data for OMAP5 with OMAP4460 voltage information.

However with the fixes introduced in later patches

commit cd8abed1da
(ARM: OMAP2+: Powerdomain: Remove the need to always have a voltdm
 associated to a pwrdm)

We are no longer restricted in that respect. Further, OPP voltage
information is supposed to be provided by dts information. This needs
to be added in future patches as various voltage modules are converted
to dts.

This also fixes the build breakage for voltagedomains54xx_data.c when just
OMAP5 SoC is enabled: https://patchwork.kernel.org/patch/2764191/

63b0420c85 ARM: AM33xx: Remove the unused voltagedomain data
Now that there is a way to tell the powerdomain core about
missing voltage domain auto-scaling control in SoCs', get rid of the dummy
voltage domain data populated for AM33xx devices.

cd8abed1da ARM: OMAP2+: Powerdomain: Remove the need to always have a voltdm associated to a pwrdm
The powerdomain framework currently expects all powerdomains to be associated with
a corresponding voltagedomain. For some SoCs' (like the already existing AM33xx
family, or for the upcoming AM437x and DRA7 SoCs') which
do not have a Voltage controller/Voltage Processor (neither the SR I2C
bus to communicate with the PMIC) there is no need for a Powerdomain to have
a voltage domain association since there is no auto-scaling of voltages possible
using the voltage FSM.

Extend the arch operations to add an api which the powerdomain core can
then use to identify if a voltdm lookup and association for a powerdomain
is really needed.

4a1b573346 ARM: 7758/1: introduce config HAS_BANDGAP
Bandgap is a device used to measure temperature on electronic
equipments.  It is widely used in digital integrated circuits.  It is
based on the dependency between silicon voltage and temperature.

This patch introduce HAS_BANDGAP config entry.  This config is a boolean
value so that arch code can flag if they feature a bandgap device.

This config entry follows the same idea behind ARCH_HAS_CPUFREQ.

f34f37160c ARM: OMAP2+: gpmc: get number of useable GPMC chip-selects via DT
This patch enables usage of DT property 'gpmc,num-cs' as already documented in
Documentation/devicetree/bindings/bus/ti-gpmc.txt

Though GPMC hardware supports upto 8 chip-selects, but all chip-selects may
not be available for use because:
- chip-select pin may not be bonded out at SoC device boundary.
- chip-select pin-mux may conflict with other pins usage.
- board level constrains.

gpmc,num-cs allows user to configure maximum number of GPMC chip-selects
available for use on any given platform. This ensures:
- GPMC child nodes having chip-selects within allowed range are only probed.
- And un-used GPMC chip-selects remain blocked.(may be for security reasons).

retained since MMC, NFS boot was not working. Since it is root caused
to be an issue with only DMA entries [1], irq can be safely removed.

c869c75c16 mailbox/omap: move the OMAP mailbox framework to drivers
The mailbox hardware (in OMAP) uses a queued mailbox interrupt
mechanism that provides a communication channel between processors
through a set of registers and their associated interrupt signals
by sending and receiving messages.

The OMAP mailbox framework/driver code is moved to be under
drivers/mailbox, in preparation for adapting to a common mailbox
driver framework. This allows the build for OMAP mailbox to be
enabled (it was disabled during the multi-platform support).

As part of the migration from plat and mach code:
- Kconfig symbols have been renamed to build OMAP1 or OMAP2+ drivers.
- mailbox.h under plat-omap/plat/include has been split into a public
  and private header files. The public header has only the API related
  functions and types.
- The module name mailbox.ko from plat-omap is changed to
  omap-mailbox.ko
- The module name mailbox_mach.ko from mach-omapX is changed as
    mailbox_omap1.ko for OMAP1
    mailbox_omap2.ko for OMAP2+

fe32c1f602 ARM: OMAP2+: add user and fifo info to mailbox platform data
The different generations of OMAP2+ SoCs have almost the same
mailbox IP, but the IP has configurable parameters for number
of users (interrupts it can generate out towards processors)
and number of fifos (the base unidirectional h/w communication
channel). This data cannot be read from any registers, and so
has been added to the platform data.

This data together with the interrupt-type configuration can be
used in properly figuring out the number of registers to save
and restore in the OMAP mailbox driver code.

to the driver through the platform data.

- external SmartReflex interface
- interface between SmartReflex driver and SmartReflex Class

Functions which belong to AVS class interface can use
struct omap_sr* instead of struct voltatedomain*, to provide a
direct connection between SR driver and SR class. This allows
us to optimize and not do additional lookups where none is
required.

sr_enable() and sr_disable() are interface functions between
SR driver and SR class. They are typically used by Class driver
to enable/disable SmartReflex hardware module.
Now they take struct omap_sr* as input parameter.

08e4830d71 ARM: OMAP5: hwmod data: Create initial OMAP5 SOC hwmod data
Adding the hwmod data for OMAP54xx SOCs.

Additional changes done on top of initial SOC data files.
- The IO resource information like dma request lines, irq number and
ocp address space can be populated via dt blob. So such data is stripped
from OMAP5 SOC hwmod data file.

- SDMA IO resource information is still kept since dmaengine work
is till ongoing. Once the legacy dma platform driver becomes obsolete,
SDMA io space information can be removed.

- The devices like dss, aess, usb which are missing the device tree bindings,
hwmod data is not added since OMAP5 is DT only build. When such devices add
the dt bindings, respective hwmod data can be added along with it.

With above update, we now need about ~2000 loc vs ~6000 loc with previous
version of the patch for OMAP5 hwmod data file. Ofcourse with addition of
few more drivers it can go upto ~2400 loc which is still better than the
earlier version.

Merge tag 'omap-fixes-b-for-3.10-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v3.10/fixes

More OMAP hwmod and clock fixes for v3.10-rc.  Fixes the AM33xx UART2.
Also fixes some CCF-related breakage on OMAP36xx/37xx, affecting DSS
at the very least.

Basic test logs for this branch are here:

3b9b10151c ARM: OMAP4: hwmod data: Clean up the data file
- The IO resource information like dma request lines, irq number and
  ocp address space can be populated via dt blob. So such data is stripped
  from OMAP4 SOC hwmod data file.

- The devices which are still missing the device tree bindings,
  address space entries are not removed yet. When such devices add
  the dt bindings, respective address space data can be deleted.

- Also other unnecessary hwmods like firewalls are removed as a part of this.
  Since emif was getting registered only because of this firewalls links,
  the mpu->emif direct link is added now.

The above update, results in reduction of about ~1650 lines of code.

49006bfd31 ARM: AM33XX: hwmod data: irq, dma and addr info clean up
AM33XX only supports DT boot mode and with addition of
extracting module resources like, irq, dma and address space
from DT block, so now we can remove duplicate information from
hwmod data file.

This patch cleanups-up/deletes,

     - All references to "omap_hwmod_irq_info" data.
     - All references to "omap_hwmod_dma_info" data.
     - References to "omap_hwmod_addr_space" of the modules
       for which DT node is available with required address
       space information.
     - For the modules where "sysc" field is not applicable,
       we don't need module address space, so remove them as well.
     - The hwmod like firewall etc which are not useful are also
       deleted.

This cleanup gets us around ~1100 LOC of negative diff.
Patch is boot tested on AM335x-EVM along with below modules -
	- Matrix-keypad
	- Volume up/down keys
	- Ethernet
	- RTC
	- WDT

45f0a85c82 PM / Runtime: Rework the "runtime idle" helper routine
The "runtime idle" helper routine, rpm_idle(), currently ignores
return values from .runtime_idle() callbacks executed by it.
However, it turns out that many subsystems use
pm_generic_runtime_idle() which checks the return value of the
driver's callback and executes pm_runtime_suspend() for the device
unless that value is not 0.  If that logic is moved to rpm_idle()
instead, pm_generic_runtime_idle() can be dropped and its users
will not need any .runtime_idle() callbacks any more.

Moreover, the PCI, SCSI, and SATA subsystems' .runtime_idle()
routines, pci_pm_runtime_idle(), scsi_runtime_idle(), and
ata_port_runtime_idle(), respectively, as well as a few drivers'
ones may be simplified if rpm_idle() calls rpm_suspend() after 0 has
been returned by the .runtime_idle() callback executed by it.

To reduce overall code bloat, make the changes described above.

2d403f7b19 ARM: OMAP3: Fix iva2_pwrdm settings for 3703
Commit a819c4f1 (ARM: OMAP3: PM: Only access IVA if one exists)
changed PM to not access IVA registers on omaps that don't have
them. Turns out we still need to idle iva2 as otherwise
iva2_pwrdm will stay on and block deeper idle states.

It seems that the only part of the reset that may not be needed
is the setting of the iva2 boot mode to idle. But as that register
seems to be there and is harmless if no iva2 is on the SoC, it's
probably safest to do the complete reset.

66dde54e97 ARM: OMAP2+: hwmod-data: UART IP needs software control to manage sidle modes
OMAP UART IP needs software control for slave idle modes based on functional
state of the IP. i.e The IP slave idle settings should be set to 'noidle' when
being used and then put back to 'smart_idle' when unused. Currently this is
handled by the driver with function pointers implemented in platform code.
This however breaks in case of device tree because of missing idle handling
APIs.

Previous patches in this series added a flag HWMOD_SWSUP_SIDLE_ACTIVE which
takes care of the mentioned requirement. Hence add the flag for all UART IPs
to take advantage of feature supported by framework.

Subsequent patches removes the slave idle handling from driver code.

ca43ea345d ARM: OMAP2+: hwmod: Add a new flag to handle SIDLE in SWSUP only in active
Some IPs (like UART) need the sidle mode to be controlled in SW only
while they are active. Once they go inactive, they need the IP to be
put back in HW control so they are also wakeup capable.

The flag HWMOD_SWSUP_SIDLE takes care of IPs which need the sidle
mode to be *always* controlled in SWSUP. We now have a need to control
IPs sidle mode in SWSUP only while its active.

So define a new flag 'HWMOD_SWSUP_SIDLE_ACT' to help the framework
know about these new IP requirements.

35513171ee ARM: OMAP2+: hwmod: Fix sidle programming in _enable_sysc()/_idle_sysc()
_enable_sysc() and _idle_sysc() handle the midle mode programming correctly
and program HWMOD_IDLEMODE_SMART or HWMOD_IDLEMODE_SMART_WKUP respectively
for supported IPs (The ones which support hardware controlled midle modes)

However the same programming logic is missing when it comes to sidle mode
programming. Here they seem to just set HWMOD_IDLEMODE_SMART (Again for the
ones which support hardware controlled sidle modes)

This problem was hidden due to the fact that a call to _enable_wakeup()
in those same functions would overwrite the idlemodes and program them
correctly (to HWMOD_IDLEMODE_SMART_WKUP in the supported cases)

So fix the sidlemode handling correctly in these functions and handle the
_enable_wakeup() for SIDLEMODE supported IPs same as the way its handled
for MIDLEMODE supported ones.

a6d25f4c95 ARM: AM33XX: Add missing .clkdm_name to clkdiv32k_ick clock
It is required to enable respective clock-domain before
enabling any clock/module inside that clock-domain.

During common-clock migration, .clkdm_name field got missed
for "clkdiv32k_ick" clock, which leaves "clk_24mhz_clkdm"
unused; so it will be disabled even if childs of this clock-domain
is enabled, which keeps child modules in idle mode.

This fixes the kernel crash observed on AM335xEVM-SK platform,
where clkdiv32_ick clock is being used as a gpio debounce clock
and since clkdiv32k_ick is in idle mode it leads to below crash -

f40739faba ARM: dts: OMAP2+: Simplify NAND support
Commit 8c8a777 (ARM: OMAP2+: Add function to read GPMC settings from
device-tree) added a device-tree property "gpmc,device-nand" to indicate
is the GPMC child device is NAND. This commit should have updated the
GPMC NAND documentation (Documentation/devicetree/bindings/mtd/gpmc-nand.txt)
to list the property "gpmc,device-nand" as a required property and also
updated the example. However, this property is redundant and not needed
because the GPMC child device node for NAND is called "nand". Therefore,
remove this property.

b1dd11d60e ARM: OMAP2+: Remove bogus IS_ERR_OR_NULL checking from id.c
Commit 6770b211 (ARM: OMAP2+: Export SoC information to userspace)
had some broken return value handling as noted by Russell King:

+       soc_dev = soc_device_register(soc_dev_attr);
+       if (IS_ERR_OR_NULL(soc_dev)) {
+               kfree(soc_dev_attr);
+               return;
+       }
+
+       parent = soc_device_to_device(soc_dev);
+       if (!IS_ERR_OR_NULL(parent))
+               device_create_file(parent, &omap_soc_attr);

This is nonsense.  For the first, IS_ERR() is sufficient.  For the second,
tell me what error checking is required in the return value of this
function:

struct device *soc_device_to_device(struct soc_device *soc_dev)
{
        return &soc_dev->dev;
}

when you've already determined that the passed soc_dev is a valid pointer.
If you read the comments against the prototype:

/**
 * soc_device_to_device - helper function to fetch struct device
 * @soc: Previously registered SoC device container
 */
struct device *soc_device_to_device(struct soc_device *soc);

if "soc" is valid, it means the "previously registered SoC device container"
must have succeeded and that can only happen if the struct device has been
registered.  Ergo, there will always be a valid struct device pointer for
any registered SoC device container.  Therefore, if soc_device_register()
succeeds, then the return value from soc_device_to_device() will always be
valid and no error checking of it is required.

Simples.  The rule as ever applies here: get to know the APIs your using
and don't fumble around in the dark hoping that you'll get this stuff
right.

Fix it as noted by Russell.

e7e17c5386 ARM: OMAP2+: omap_device: use late_initcall_sync
If DEBUG_LL and earlyprintk are enabled, and omap-serial.c is compiled
as a module, the kernel boot hangs early as the clocks for serial port
are cut while earlyprintk still uses the port.

The problem is a race between the late_initcall for omap_device (which
idles devices that have no drivers) and the late_initcall in
kernel/printk.c which turns off the earlyconsole.   Any printks
that happen between this omap_device late initcall and the earlyconsole
late initcall will crash when accessing the UART.

The fix is to ensure the omap_device initcall happens after the
earlyconsole initcall.

e65f131a14 ARM: OMAP: RX-51: change probe order of touchscreen and panel SPI devices
Commit 9fdca9df (spi: omap2-mcspi: convert to module_platform_driver)
broke the SPI display/panel driver probe on RX-51/N900. The exact cause is
not fully understood, but it seems to be related to the probe order. SPI
communication to the panel driver (spi1.2) fails unless the touchscreen
(spi1.0) has been probed/initialized before. When the omap2-mcspi driver
was converted to a platform driver, it resulted in that the devices are
probed immediately after the board registers them in the order they are
listed in the board file.

Fix the issue by moving the touchscreen before the panel in the SPI
device list.

The patch fixes the following failure:

[    1.260955] acx565akm spi1.2: invalid display ID
[    1.265899] panel-acx565akm display0: acx_panel_probe panel detect error

I badly screwed up the merge in commit 6fa52ed33b ("Merge tag

incorrectly taking the arch/arm/mach-omap2/* data fully from the merge
target because the 'drivers-for-linus' branch seemed to be a proper
superset of the duplicate ARM commits.

That was bogus: commit ff931c821b ("ARM: OMAP: clocks: Delay clk inits
atleast until slab is initialized") only existed in head, and the
changes to arch/arm/mach-omap2/timer.c from that commit got list.

Re-doing the merge more carefully, I do think this part was the only
thing I screwed up.  Knock wood.

1bf25e78af ARM: arm-soc: late cleanups
These are cleanups and smaller changes that either depend on earlier
 feature branches or came in late during the development cycle.
 We normally try to get all cleanups early, so these are the exceptions:
 
 - A follow-up on the clocksource reworks, hopefully the last time
   we need to merge clocksource subsystem changes through arm-soc.
   A first set of patches was part of the original 3.10 arm-soc cleanup
   series because of interdependencies with timer drivers now moved out
   of arch/arm.
 
 - Migrating the SPEAr13xx platform away from using auxdata for DMA
   channel descriptions towards using information in device tree,
   based on the earlier SPEAr multiplatform series
 
 - A few follow-ups on the Atmel SAMA5 support and other changes
   for Atmel at91 based on the larger at91 reworks.
 
 - Moving the armada irqchip implementation to drivers/irqchip
 
 - Several OMAP cleanups following up on the larger series already
   merged in 3.10.

Merge tag 'cleanup-for-linus-2' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC late cleanups from Arnd Bergmann:
 "These are cleanups and smaller changes that either depend on earlier
  feature branches or came in late during the development cycle.  We
  normally try to get all cleanups early, so these are the exceptions:

   - A follow-up on the clocksource reworks, hopefully the last time we
     need to merge clocksource subsystem changes through arm-soc.

     A first set of patches was part of the original 3.10 arm-soc
     cleanup series because of interdependencies with timer drivers now
     moved out of arch/arm.

   - Migrating the SPEAr13xx platform away from using auxdata for DMA
     channel descriptions towards using information in device tree,
     based on the earlier SPEAr multiplatform series

   - A few follow-ups on the Atmel SAMA5 support and other changes for
     Atmel at91 based on the larger at91 reworks.

   - Moving the armada irqchip implementation to drivers/irqchip

   - Several OMAP cleanups following up on the larger series already
     merged in 3.10."
