e6c81cce56 ARM: SoC platform updates for v4.1
Our SoC branch usually contains expanded support for new SoCs and other core
 platform code. In this case, that includes:
 
 - Support for the new Annapurna Labs "Alpine" platform
 - A rework greatly simplifying adding new platform support to the MCPM
   subsystem (Multi-cluster power management)
 - Cpuidle and PM improvements for Exynos3250
 - Misc updates for Renesas, OMAP, Meson, i.MX. Some of these could have
   gone in other branches but ended up here for various reasons.

8b283c0254 ARM: exynos4/5: convert pmu wakeup to stacked domains
Exynos has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the fact that the PMU block is actually the first
interrupt controller in the chain for RTC, kernels with this patch
applied wont have any suspend-resume facility when booted
with old DTs, and old kernels with updated DTs may not even boot.

Also, I strongly suspect that there is more than two wake-up
interrupts on these platforms, but I leave it to the maintainers
to fix their mess.

The Exynos cpuidle driver has coupled cpuidle built-in so it cannot be
built without SMP:

arch/arm/mach-exynos/pm.c: In function 'exynos_cpu0_enter_aftr':
arch/arm/mach-exynos/pm.c:246:4: error: implicit declaration of function 'arch_send_wakeup_ipi_mask' [-Werror=implicit-function-declaration]

arch/arm/mach-exynos/built-in.o: In function 'exynos_cpu1_powerdown':
../arch/arm/mach-exynos/pm.c:282: undefined reference to 'exynos_cpu_power_down'

Fix it by adding missing checks for SMP.

543c5040f5 ARM: make arrays containing machine compatible strings const
The definition

	static const char *axxia_dt_match[] __initconst = {
		...

defines a changable array of constant strings. That is you must not do:

	*axxia_dt_match[0] = 'k';

but

	axxia_dt_match[0] = "different string";

is fine. So the annotation __initconst is wrong and yields a compiler
error when other really const variables are added with __initconst.

As the struct machine_desc member dt_compat is declared as

	const char *const *dt_compat;

making the arrays const is the better alternative over changing all
annotations to __initdata.

878ba61aa9 ARM: SoC platform changes
New and updated SoC support. Also included are some cleanups where the
 platform maintainers hadn't separated cleanups from new developent in
 separate branches.
 
 Some of the larger things worth pointing out:
 
 - A large set of changes from Alexandre Belloni and Nicolas Ferre
   preparing at91 platforms for multiplatform and cleaning up quite a
   bit in the process.
 - Removal of CSR's "Marco" SoC platform that never made it out to the
   market. We love seeing these since it means the vendor published
   support before product was out, which is exactly what we want!
 
 New platforms this release are:
 
 - Conexant Digicolor (CX92755 SoC)
 - Hisilicon HiP01 SoC
 - CSR/sirf Atlas7 SoC
 - ST STiH418 SoC
 - Common code changes for Nvidia Tegra132 (64-bit SoC)
 
 We're seeing more and more platforms having a harder time labelling
 changes as cleanups vs new development -- which is a good sign that
 we've come quite far on the cleanup effort. So over time we might start
 combining the cleanup and new-development branches more.

712eddf702 cpuidle: exynos: add coupled cpuidle support for exynos4210
The following patch adds coupled cpuidle support for Exynos4210 to
an existing cpuidle-exynos driver.  As a result it enables AFTR mode
to be used by default on Exynos4210 without the need to hot unplug
CPU1 first.

The patch is heavily based on earlier cpuidle-exynos4210 driver from
Daniel Lezcano:

http://www.spinics.net/lists/linux-samsung-soc/msg28134.html

Changes from Daniel's code include:
- porting code to current kernels
- fixing it to work on my setup (by using S5P_INFORM register
  instead of S5P_VA_SYSRAM one on Revison 1.1 and retrying poking
  CPU1 out of the BOOT ROM if necessary)
- fixing rare lockup caused by waiting for CPU1 to get stuck in
  the BOOT ROM (CPU hotplug code in arch/arm/mach-exynos/platsmp.c
  doesn't require this and works fine)
- moving Exynos specific code to arch/arm/mach-exynos/pm.c
- using cpu_boot_reg_base() helper instead of BOOT_VECTOR macro
- using exynos_cpu_*() helpers instead of accessing registers
  directly
- using arch_send_wakeup_ipi_mask() instead of dsb_sev()
  (this matches CPU hotplug code in arch/arm/mach-exynos/platsmp.c)
- integrating separate exynos4210-cpuidle driver into existing
  exynos-cpuidle one

d4e1f5a14e ARM: SoC device-tree changes for 3.17
Unlike the board branch, this keeps having large sets of changes for
 every release, but that's quite expected and is so far working well.
 
 Most of this is plumbing for various device bindings and new platforms,
 but there's also a bit of cleanup and code removal for things that
 are moved from platform code to DT contents (some OMAP clock code in
 particular).
 
 There's also a pinctrl driver for tegra here (appropriately acked),
 that's introduced this way to make it more bisectable.
 
 I'm happy to say that there were no conflicts at all with this branch
 this release, which means that changes are flowing through our tree as
 expected instead of merged through driver maintainers (or at least not
 done with conflicts).
 
 There are several new boards added, and a couple of SoCs. In no particular
 order:
 
 * Rockchip RK3288 SoC support, including DTS for a dev board that they
   have seeded with some community developers.
 * Better support for Hardkernel Exynos4-based ODROID boards.
 * CCF conversions (and dtsi contents) for several Renesas platforms.
 * Gumstix Pepper (TI AM335x) board support
 * TI eval board support for AM437x
 * Allwinner A23 SoC, very similar to existing ones which mostly has
   resulted in DT changes for support. Also includes support for an Ippo
   tablet with the chipset.
 * Allwinner A31 Hummingbird board support, not to be confused with the
   SolidRun i.MX-based Hummingboard.
 * Tegra30 Apalis board support

 * More additions of Renesas shmobile platform support
 * Removal of plat-samsung contents that can be removed with S5PV210 being

 * Hisilicon X5HD2 settop box chipset is introduced
 * Mediatek MT6589 (mobile chipset) is introduced
 * Broadcom BCM7xxx settop box chipset is introduced

44c916d58b ARM: SoC cleanups for 3.17
This merge window brings a good size of cleanups on various
 platforms. Among the bigger ones:
 
 * Removal of Samsung s5pc100 and s5p64xx platforms. Both of these have
   lacked active support for quite a while, and after asking around nobody
   showed interest in keeping them around. If needed, they could be
   resurrected in the future but it's more likely that we would prefer
   reintroduction of them as DT and multiplatform-enabled platforms
   instead.
 * OMAP4 controller code register define diet. They defined a lot of registers
   that were never actually used, etc.
 * Move of some of the Tegra platform code (PMC, APBIO, fuse, powergate)
   to drivers/soc so it can be shared with 64-bit code. This also converts them
   over to traditional driver models where possible.

Merge tag 'cleanup-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Olof Johansson:
 "This merge window brings a good size of cleanups on various platforms.
  Among the bigger ones:

   - Removal of Samsung s5pc100 and s5p64xx platforms.  Both of these
     have lacked active support for quite a while, and after asking
     around nobody showed interest in keeping them around.  If needed,
     they could be resurrected in the future but it's more likely that
     we would prefer reintroduction of them as DT and
     multiplatform-enabled platforms instead.

   - OMAP4 controller code register define diet.  They defined a lot of
     registers that were never actually used, etc.

   - Move of some of the Tegra platform code (PMC, APBIO, fuse,
     powergate) to drivers/soc so it can be shared with 64-bit code.
     This also converts them over to traditional driver models where
     possible.

   - Removal of legacy gpio-samsung driver, since the last users have
     been removed (moved to pinctrl)

  Plus a bunch of smaller changes for various platforms that sort of
  dissapear in the diffstat for the above.  clps711x cleanups, shmobile

5a12a597a8 arm: Add devicetree fixup machine function
Commit 1c2f87c225
(ARM: 8025/1: Get rid of meminfo) dropped the upper bound on
the number of memory banks that can be added as there was no
technical need in the kernel. It turns out though, some bootloaders
(specifically the arndale-octa exynos boards) may pass invalid memory
information and rely on the kernel to not parse this data. This is a
bug in the bootloader but we still need to work around this.
Work around this by introducing a dt_fixup function. This function
gets called before the flattened devicetree is scanned for memory
and the like. In this fixup function for exynos, limit the maximum
number of memory regions in the devicetree.

As exynos_cpuidle_init() and exynos_cpufreq_init() functions have just
one line of code for registering platform devices. So we can move them
to exynos_dt_machine_init() and remove exynos_cpuidle_init() and
exynos_cpufreq_init(). This will help in reducing lines of code in

2e94ac4289 ARM: EXYNOS: Refactored code for using PMU address via DT
Under "arm/mach-exynos" many files are using PMU register offsets.
Since we have added support for accessing PMU base address via DT,
now we can remove PMU mapping from exynosX_iodesc. Let's convert
all these access using iomapped address.
This will help us in removing static mapping of PMU base address
as well as help in reducing dependency over machine header files.
Thus helping for migration of PMU implementation from machine to
driver folder which can be reused for ARM64 based SoC.

Also as we have removed static mappings from "regs-pmu.h" it does
not need map.h anymore. But "platsmp.c" needed this and till now it
got included indirectly. So lets move header inclusion of
"mach/map.h" from "regs-pmu.h" to "platsmp.c".

Currently, the exynos cpuidle driver works correctly only on exynos4210
and 5250. Trying to use it with just one CPU online on any other exynos
SoCs will lead to system failure, due to unsupported AFTR mode on other
SoCs. This patch fixes the problem by registering the driver only on
supported SoCs and letting others simply use default WFI mode until
support for them is added.

This solves a problem with building with CONFIG_SMP=n due to missing

The new setup method is more awkward than I'd like for it to be, but
it can't be done in init_early() since ioremap is not yet available,
but it needs to happen before SMP.

Pull ARM updates from Russell King:

 - Major clean-up of the L2 cache support code.  The existing mess was
   becoming rather unmaintainable through all the additions that others
   have done over time.  This turns it into a much nicer structure, and
   implements a few performance improvements as well.

 - Clean up some of the CP15 control register tweaks for alignment
   support, moving some code and data into alignment.c

 - DMA properties for ARM, from Santosh and reviewed by DT people.  This
   adds DT properties to specify bus translations we can't discover
   automatically, and to indicate whether devices are coherent.

 - Hibernation support for ARM

 - Make ftrace work with read-only text in modules

 - add suspend support for PJ4B CPUs

 - rework interrupt masking for undefined instruction handling, which
   allows us to enable interrupts earlier in the handling of these
   exceptions.

 - support for big endian page tables

 - fix stacktrace support to exclude stacktrace functions from the
   trace, and add save_stack_trace_regs() implementation so that kprobes
   can record stack traces.

 - Add support for the Cortex-A17 CPU.

 - Remove last vestiges of ARM710 support.

 - Removal of ARM "meminfo" structure, finally converting us solely to
   memblock to handle the early memory initialisation.

a727eaf64f ARM: SoC driver changes
SoC-near driver changes that we're merging through our tree. Mostly
 because they depend on other changes we have staged, but in some cases
 because the driver maintainers preferred that we did it this way.
 
 This contains a largeish cleanup series of the omap_l3_noc bus driver,
 cpuidle rework for Exynos, some reset driver conversions and a long
 branch of TI EDMA fixes and cleanups, with more to come next release.
 
 The TI EDMA cleanups is a shared branch with the dmaengine tree, with
 a handful of Davinci-specific fixes on top.
 
 After discussion at last year's KS (and some more on the mailing lists),
 we are here adding a drivers/soc directory. The purpose of this is
 to keep per-vendor shared code that's needed by different drivers but
 that doesn't fit into the MFD (nor drivers/platform) model. We expect
 to keep merging contents for this hierarchy through arm-soc so we can
 keep an eye on what the vendors keep adding here and not making it a
 free-for-all to shove in crazy stuff.

Merge tag 'drivers-for-3.16' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc into next

Pull ARM SoC driver changes from Olof Johansson:
 "SoC-near driver changes that we're merging through our tree.  Mostly
  because they depend on other changes we have staged, but in some cases
  because the driver maintainers preferred that we did it this way.

  This contains a largeish cleanup series of the omap_l3_noc bus driver,
  cpuidle rework for Exynos, some reset driver conversions and a long
  branch of TI EDMA fixes and cleanups, with more to come next release.

  The TI EDMA cleanups is a shared branch with the dmaengine tree, with
  a handful of Davinci-specific fixes on top.

  After discussion at last year's KS (and some more on the mailing
  lists), we are here adding a drivers/soc directory.  The purpose of
  this is to keep per-vendor shared code that's needed by different
  drivers but that doesn't fit into the MFD (nor drivers/platform)
  model.  We expect to keep merging contents for this hierarchy through
  arm-soc so we can keep an eye on what the vendors keep adding here and
  not making it a free-for-all to shove in crazy stuff"

b5b9324a62 ARM: exynos: don't run exynos4 l2x0 setup on other platforms
This was caught by a panic on Broadcom mobile platforms.

Note that this code is all going away with the pending l2x0 cleanup
series from Russell, but we need this here until that's landed so we
can enable exynos multiplatform.

- add new SoCs support
   : exynos3250, 5260, 5410 and 5800
 
 - enable multi-platform on exynos
   : consolidate exynos related Kconfig entries
 
 Note that this requires tags/samsung-cleanup and tags/samsung-clk-2
 because of mostly migration exynos specific macros into mach-exynos
 and exynos related Kconfig entries.
 
 One more merge conflict happens in arch/arm/Kconfig for ARCH_EXYNOS
 due to SRAM stuff, even though tried to sort them out. Since just
 resolving it would be better I think, please remove ARCH_EXYNOS in
 arch/arm/Kconfig when merge conflict happens.

15b0bc4041 ARM: l2c: exynos: convert to generic l2c OF initialisation (and thereby fix it)
exynos was unconditionally calling the L2 cache initialisation from an
early_initcall.  This breaks multiplatform kernels.  Thankfully,
converting to generic l2c initialisation fixes this.

The cache size should already be present in the L2 cache auxiliary
control register: it is part of the integration process to configure
the hardware IP.  Most platforms get this right, yet still many
cargo-cult program, and assume that they always need specifying to
the L2 cache code.  Remove them so we can find out which really need
this.

Since we now automatically enable early BRESP in core L2C-310 code when
we detect a Cortex-A9, we don't need platforms/SoCs to set this bit
explicitly.  Instead, they should seek to preserve the value of bit 30
