4dddfb8823 ARM: S3C64XX: Use PWM lookup table for mach-smartq
Use a PWM lookup table to provide the PWM to the pwm-backlight device.
The driver has a legacy code path that is required only because boards
still use the legacy method of requesting PWMs by global ID. Replacing
these usages allows that legacy fallback to be removed.

bd0b9ac405 genirq: Remove irq argument from irq flow handlers
Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

c5fc249862 ARM: SoC cleanups for v4.3
A large cleanup branch this release, with a healthy 10k negative line delta.
 
 Most of this is removal of legacy (non-DT) support of shmobile
 platforms. There is also removal of two non-DT platforms on OMAP,
 and the plat-samsung directory is cleaned out by moving most of the
 previously shared-location-but-not-actually-shared files from there to
 the appropriate mach directories instead.
 
 There are other sets of changes in here as well:
 
  - Rob Herring removed use of set_irq_flags under all platforms and
    moved to genirq alternatives
  - A series of timer API conversions to set-state interface
  - ep93xx, nomadik and ux500 cleanups from Linus Walleij
  - __init annotation fixes from Nicolas Pitre
  + a bunch of other changes that all add up to a nice set of cleanups

Rob Herring
e8d36d5dbb ARM: kill off set_irq_flags usage
set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

Init data marked const should be annotated with __initconst for
correctness and not __initdata.  In some cases the array gathering
references to that data has to be marked const as well. This fixes
LTO builds that otherwise fail with section mismatch errors.

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.

eeebc3bb4d ARM: cpuidle: Remove duplicate header inclusion
The cpu_do_idle() function is always used by the cpuidle drivers.

That led to have each driver including cpuidle.h and proc-fns.h, they are
always paired. That makes a lot of duplicate headers inclusion. Instead of
including both in each .c file, move the proc-fns.h header inclusion in the
cpuidle.h header file directly, so we can save some line of code.

b82b6cca48 cpuidle: Invert CPUIDLE_FLAG_TIME_VALID logic
The only place where the time is invalid is when the ACPI_CSTATE_FFH entry
method is not set. Otherwise for all the drivers, the time can be correctly
measured.

Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers
for all the states, just invert the logic by replacing it by the flag
CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle
driver, remove the former flag from all the drivers and invert the logic with
this flag in the different governor.

27873b052e ARM: samsung: make SAMSUNG_DMADEV optional
The only remaining driver using the samsung dmadev code is the broken
samsung-ac97 sound driver. However, as found by Russell's autobuilder,
the elaborate dependency chains around it cause problems with
circular dependencies.

This is an attempt to simplify those dependencies by making the
SAMSUNG_DMADEV option user-selectable. I also try to keep the
default settings for all related options unchanged, so we don't
introduce any regressions against earlier testing on linux-next.

In particular, all s3c64xx and s5p* platforms keep selecting the
pl330 and pl08x drivers they require, but the select statement
is now moved towards the main platform option, and it remains
optional by unselecting CONFIG_DMADEVICES.

Merge tag 'cleanup-3.15' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc

Pull ARM SoC cleanups from Arnd Bergmann:
 "These cleanup patches are mainly move stuff around and should all be
  harmless.  They are mainly split out so that other branches can be
  based on top to avoid conflicts.

  Notable changes are:

   - We finally remove all mach/timex.h, after CLOCK_TICK_RATE is no
     longer used (Uwe Kleine-König)
   - The Qualcomm MSM platform is split out into legacy mach-msm and
     new-style mach-qcom, to allow easier maintainance of the new
     hardware support without regressions (Kumar Gala)
   - A rework of some of the Kconfig logic to simplify multiplatform
     support (Rob Herring)
   - Samsung Exynos gets closer to supporting multiplatform (Sachin
     Kamat and others)
   - mach-bcm3528 gets merged into mach-bcm (Stephen Warren)
   - at91 gains some common clock framework support (Alexandre Belloni,
     Jean-Jacques Hiblot and other French people)"

baf64abc46 ARM: S3C64XX: mach-crag6410-module.c is not modular
Despite the name mach-crag6410-module.c, the code is built for
MACH_WLF_CRAGG_6410 -- which is bool, and hence this code is
either present or absent.  It will never be modular, so using
module_init as an alias for __initcall can be somewhat
misleading.

Fix this up now, so that we can relocate module_init from
init.h into module.h in the future.  If we don't do this, we'd
have to add module.h to obviously non-modular code, and that
would be a worse thing.

Note that direct use of __initcall is discouraged, vs. one
of the priority categorized subgroups.  As __initcall gets
mapped onto device_initcall, our use of device_initcall
directly in this change means that the runtime impact is
zero -- it will remain at level 6 in initcall ordering.

f2c73464d7 ARM: SoC cleanups for 3.14
This is the branch where we usually queue up cleanup efforts, moving
 drivers out of the architecture directory, header file restructuring,
 etc. Sometimes they tangle with new development so it's hard to keep it
 strictly to cleanups.
 
 Some of the things included in this branch are:
 
 * Atmel SAMA5 conversion to common clock
 * Reset framework conversion for tegra platforms
  - Some of this depends on tegra clock driver reworks that are shared with Mike
    Turquette's clk tree.
 * Tegra DMA refactoring, which are shared branches with the DMA tree.
 * Removal of some header files on exynos to prepare for multiplatform

d4371f94bc sound updates for 3.14-rc1
It was holiday season, so no wonder that there are little changes in
 framework level, although diffstat shows quite many changes spreaded
 over sound/* directories.  Most of changes are cleanups, code
 refactoring and fixes.
 
 Some highlights:
 
 - Removal of OSS sleep_on usages by Arnd
 
 - Simplified memalloc helper codes, drop obsoleted features;
   now it's built into PCM driver instead of an individual module
 
 - Warn if PCM buffer preallocation fails, which will show page
   allocation issues more clearly
 
 - Compress offload API updates for sample rates by Vinod
 
 - PCM glitch workaround on ctxfi emu20k1 by Sarah
 
 - Drop cs46xx DSP blobs, using firmware loader now
 
 - USB-audio quitks for Plantronics Gamecom 780, Creative VF0420,
   and Focusrite Saffire 6
 
 HD-audio specifics:
 
 - Standardize Kconfigs of HD-audio codec drivers;
   now "make localmodconfig" recognizes configs properly (finally!)
 
 - Parallel PM implementation by Mengdong
 
 - BayleyBay/ValleyView2 board fixups
 
 - Broadwell audio support
 
 - Runtime PM improvement (PantherPoint, etc)
 
 - Quirks: Dell subwooer, Gigabyte mobo jack detection oddity,
   Dell AiO click noise fixes, Dell headset mic fixes, etc
 
 - Automatic bind with HDMI codec parser without generic parser
 
 - More AD codec fixes (since 3.12 regression) including the automatic
   stereo mix support
 
 - Common Thinkpad ACPI helper for Realtek and Conexant codecs
 
 ASoC specifics:
 
 - Update to the generic DMA code to support deferred probe and managed
   resources
 
 - New drivers for BCM2835 (used in Raspberry Pi), Tegra with MAX98090
   and Analog Devices AXI I2S and S/PDIF controller IPs
 
 - Device tree support for the simple card, max98090 and cs42l52
 
 - Conversion of the Samsung drivers to native dmaengine, making them
   multiplatform compatible and hopefully helping keep them more modern
   and up to date.
 
 - More regmap conversions, including a very welcome one for twl6040
   from Peter Ujfalusi
 
 - A big overhaul of the DaVinci drivers also from Peter Ujfalusi
 
 - Lots of DMA updates from Lars-Peter
 
 - Improvements to the constraints handling code from Lars-Peter
 
 - A very helpful conversion of the TWL4030 driver to regmap from Peter
 
 - A new driver for the Freescale ESAI controller from Nicolin Chen
 
 - Conversion of some of the drivers to use params_width()
 
 - Extensions to DPCM for use with compressed audio from Liam
