b9f2b21a32 Devicetree changes for v3.15
Updates to devicetree core code. This branch contains the following notable changes:
 * Add reserved memory binding
 * Make struct device_node a kobject and remove legacy /proc/device-tree
 * ePAPR conformance fixes
 * Update in-kernel DTC copy to version v1.4.0
 * Preparation changes for dynamic device tree overlays
 * minor bug fixes and documentation changes
 
 The most significant change in this branch is the conversion of struct
 device_node to be a kobject that is exposed via sysfs and removal of the
 old /proc/device-tree code. This simplifies the device tree handling
 code and tightens up the lifecycle on device tree nodes.
 
 [updated: added fix for dangling select PROC_DEVICETREE]

0829f6d1f6 of: device_node kobject lifecycle fixes
After the move to having device nodes be proper kobjects the lifecycle
of the node needs to be controlled better.

At first convert of_add_node() in the unflattened functions to
of_init_node() which initializes the kobject so that of_node_get/put
work correctly even before of_init is called.

Afterwards introduce of_node_is_initialized & of_node_is_attached that
query the underlying kobject about the state (attached means kobj
is visible in sysfs)

Using that make sure the lifecycle of the tree is correct at all
times.

The same data is now available in sysfs, so we can remove the code
that exports it in /proc and replace it with a symlink to the sysfs
version.

Tested on versatile qemu model and mpc5200 eval board. More testing
would be appreciated.

75b57ecf9d of: Make device nodes kobjects so they show up in sysfs
Device tree nodes are already treated as objects, and we already want to
expose them to userspace which is done using the /proc filesystem today.
Right now the kernel has to do a lot of work to keep the /proc view in
sync with the in-kernel representation. If device_nodes are switched to
be kobjects then the device tree code can be a whole lot simpler. It
also turns out that switching to using /sysfs from /proc results in
smaller code and data size, and the userspace ABI won't change if
/proc/device-tree symlinks to /sys/firmware/devicetree/base.

v7: Add missing sysfs_bin_attr_init()
v6: Add __of_add_property() early init fixes from Pantelis
v5: Rename firmware/ofw to firmware/devicetree
    Fix updating property values in sysfs
v4: Fixed build error on Powerpc
    Fixed handling of dynamic nodes on powerpc
v3: Fixed handling of duplicate attribute and child node names
v2: switch to using sysfs bin_attributes which solve the problem of
    reporting incorrect property size.

ad54a0cfbe of: add functions to count number of elements in a property
The need to know the number of array elements in a property is
a common pattern. To prevent duplication of open-coded implementations
add a helper static function that also centralises strict sanity
checking and DTB format details, as well as a set of wrapper functions
for u8, u16, u32 and u64.

662372e42e of: restructure for_each macros to fix compile warnings
Commit 00b2c76a6a "include/linux/of.h: make for_each_child_of_node()
reference its args when CONFIG_OF=n" fixed warnings for unused
variables, but introduced variable "used uninitialized" warnings.
Simply initializing the variables would result in "set but not used"
warnings with W=1.

Fix both types of warnings by making all the for_each macros
unconditional and rely on the dummy static inline functions to
initialize and reference any variables.

b66548e2a9 of: Increase MAX_PHANDLE_ARGS
arm-smmu driver uses of_parse_phandle_with_args when parsing DT
information to determine stream IDs for a master device.
Thus the number of stream IDs per master device is bound by
MAX_PHANDLE_ARGS.

To support Calxeda ECX-2000 hardware arm-smmu driver requires a
slightly higher value for MAX_PHANDLE_ARGS as this hardware has 10
stream IDs for one master device.

Increasing it to 16 seems a reasonable choice.

40031da445 ACPI and power management updates for 3.12-rc1
1) ACPI-based PCI hotplug (ACPIPHP) subsystem rework and introduction
     of Intel Thunderbolt support on systems that use ACPI for signalling
     Thunderbolt hotplug events.  This also should make ACPIPHP work in
     some cases in which it was known to have problems.  From
     Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov.
 
  2) ACPI core code cleanups and dock station support cleanups from
     Jiang Liu and Rafael J Wysocki.
 
  3) Fixes for locking problems related to ACPI device hotplug from
     Rafael J Wysocki.
 
  4) ACPICA update to version 20130725 includig fixes, cleanups, support
     for more than 256 GPEs per GPE block and a change to make the ACPI
     PM Timer optional (we've seen systems without the PM Timer in the
     field already).  One of the fixes, related to the DeRefOf operator,
     is necessary to prevent some Windows 8 oriented AML from causing
     problems to happen.  From Bob Moore, Lv Zheng, and Jung-uk Kim.
 
  5) Removal of the old and long deprecated /proc/acpi/event interface
     and related driver changes from Thomas Renninger.
 
  6) ACPI and Xen changes to make the reduced hardware sleep work with
     the latter from Ben Guthro.
 
  7) ACPI video driver cleanups and a blacklist of systems that should
     not tell the BIOS that they are compatible with Windows 8 (or ACPI
     backlight and possibly other things will not work on them).  From
     Felipe Contreras.
 
  8) Assorted ACPI fixes and cleanups from Aaron Lu, Hanjun Guo,
     Kuppuswamy Sathyanarayanan, Lan Tianyu, Sachin Kamat, Tang Chen,
     Toshi Kani, and Wei Yongjun.
 
  9) cpufreq ondemand governor target frequency selection change to
     reduce oscillations between min and max frequencies (essentially,
     it causes the governor to choose target frequencies proportional
     to load) from Stratos Karafotis.

Pull ACPI and power management updates from Rafael Wysocki:

 1) ACPI-based PCI hotplug (ACPIPHP) subsystem rework and introduction
    of Intel Thunderbolt support on systems that use ACPI for signalling
    Thunderbolt hotplug events.  This also should make ACPIPHP work in
    some cases in which it was known to have problems.  From
    Rafael J Wysocki, Mika Westerberg and Kirill A Shutemov.

 2) ACPI core code cleanups and dock station support cleanups from
    Jiang Liu and Rafael J Wysocki.

 3) Fixes for locking problems related to ACPI device hotplug from
    Rafael J Wysocki.

 4) ACPICA update to version 20130725 includig fixes, cleanups, support
    for more than 256 GPEs per GPE block and a change to make the ACPI
    PM Timer optional (we've seen systems without the PM Timer in the
    field already).  One of the fixes, related to the DeRefOf operator,
    is necessary to prevent some Windows 8 oriented AML from causing
    problems to happen.  From Bob Moore, Lv Zheng, and Jung-uk Kim.

 5) Removal of the old and long deprecated /proc/acpi/event interface
    and related driver changes from Thomas Renninger.

 6) ACPI and Xen changes to make the reduced hardware sleep work with
    the latter from Ben Guthro.

 7) ACPI video driver cleanups and a blacklist of systems that should
    not tell the BIOS that they are compatible with Windows 8 (or ACPI
    backlight and possibly other things will not work on them).  From
    Felipe Contreras.

    Kuppuswamy Sathyanarayanan, Lan Tianyu, Sachin Kamat, Tang Chen,
    Toshi Kani, and Wei Yongjun.

 9) cpufreq ondemand governor target frequency selection change to
    reduce oscillations between min and max frequencies (essentially,
    it causes the governor to choose target frequencies proportional
    to load) from Stratos Karafotis.

183912d352 of: move of_get_cpu_node implementation to DT core library
This patch moves the generalized implementation of of_get_cpu_node from
PowerPC to DT core library, thereby adding support for retrieving cpu
node for a given logical cpu index on any architecture.

The CPU subsystem can now use this function to assign of_node in the
cpu device while registering CPUs.

It is recommended to use these helper function only in pre-SMP/early
initialisation stages to retrieve CPU device node pointers in logical
ordering. Once the cpu devices are registered, it can be retrieved easily
from cpu device of_node which avoids unnecessary parsing and matching.

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.

6fa52ed33b ARM: arm-soc driver changes for 3.10
This is a rather large set of patches for device drivers that for one
 reason or another the subsystem maintainer preferred to get merged
 through the arm-soc tree. There are both new drivers as well as
 existing drivers that are getting converted from platform-specific
 code into standalone drivers using the appropriate subsystem
 specific interfaces.
 
 In particular, we can now have pinctrl, clk, clksource and irqchip
 drivers in one file per driver, without the need to call into
 platform specific interface, or to get called from platform specific
 code, as long as all information about the hardware is provided
 through a device tree.
 
 Most of the drivers we touch this time are for clocksource. Since
 now most of them are part of drivers/clocksource, I expect that we
 won't have to touch these again from arm-soc and can let the
 clocksource maintainers take care of these in the future.
 
 Another larger part of this series is specific to the exynos platform,
 which is seeing some significant effort in upstreaming and
 modernization of its device drivers this time around, which
 unfortunately is also the cause for the churn and a lot of the
 merge conflicts.
 
 There is one new subsystem that gets merged as part of this series:
 the reset controller interface, which is a very simple interface
 for taking devices on the SoC out of reset or back into reset.
 Patches to use this interface on i.MX follow later in this merge
 window, and we are going to have other platforms (at least tegra
 and sirf) get converted in 3.11. This will let us get rid of
 platform specific callbacks in a number of platform independent
 device drivers.

bd69f73f2c of: Create function for counting number of phandles in a property
This patch creates of_count_phandle_with_args(), a new function for
counting the number of phandle+argument tuples in a given property. This
is better than the existing method of parsing each phandle individually
until parsing fails which is a horribly slow way to do the count.

Tested on ARM using the selftest code.

v3: - Rebased on top of selftest code cleanup patch
v2: - fix bug where of_parse_phandle_with_args() could behave like _count_.
    - made of_gpio_named_count() into a static inline regardless of CONFIG_OF_GPIO

d6d3c4e656 OF: convert devtree lock from rw_lock to raw spinlock
With the locking cleanup in place (from "OF: Fixup resursive
locking code paths"), we can now do the conversion from the
rw_lock to a raw spinlock as required for preempt-rt.

The previous cleanup and this conversion were originally
separate since they predated when mainline got raw spinlock (in
commit c2f21ce2e3 "locking: Implement new raw_spinlock").

So, at that point in time, the cleanup was considered plausible
for mainline, but not this conversion.  In any case, we've kept
them separate as it makes for easier review and better bisection.

50c8af4cf9 of: introduce for_each_matching_node_and_match()
The following pattern of code is tempting:

    for_each_matching_node(np, table) {
        match = of_match_node(table, np);

However, this results in iterating over table twice; the second time
inside of_match_node(). The implementation of for_each_matching_node()
already found the match, so this is redundant. Invent new function
of_find_matching_node_and_match() and macro
for_each_matching_node_and_match() to remove the double iteration,
thus transforming the above code to:

    for_each_matching_node_and_match(np, table, &match)

This patch moves the notification chain for updates to the device tree
from the powerpc/pseries code to the base OF code. This makes this
functionality available to all architectures.

Additionally the notification chain is updated to allow notifications
for property add/remove/update. To make this work a pointer to a new
struct (of_prop_reconfig) is passed to the routines in the notification chain.
The of_prop_reconfig property contains a pointer to the node containing the
property and a pointer to the property itself. In the case of property
updates, the property pointer refers to the new property.
