Wolfram Sang a46ca32ca0 ARM: mach-msm: drop owner assignment from platform_drivers
A platform_driver does not need to set an owner, it will be populated by the
driver core.

Georgi Djakov 77cfe68e28 ARM: msm: Update the references to DEBUG_MSM_UARTx
The Kconfig options DEBUG_MSM_UART1, DEBUG_MSM_UART2, DEBUG_MSM_UART3,
MSM_DEBUG_UART1, MSM_DEBUG_UART2 and MSM_DEBUG_UART3 are removed, but
they are still referenced in the following files:
	arch/arm/mach-msm/io.c,
	arch/arm/mach-msm/board-trout.c
	arch/arm/mach-msm/board-trout-gpio.c

Fix this by updating the reference to the new Kconfig option.

Linus Walleij 262334ae21 ARM: msm: remove reference to MSM_SERIAL_DEBUGGER
This is a dangling symbol in the kernel: there is no config option

Linus Walleij 8ead9f949d ARM: msm: delete dangling mahimahi board file
This board file is not compiled, and includes header files that
do not even exist so it can't be made to compile easily either.
I assume it is a merge mistake, thus deleting it.

Linus Torvalds eb3d3ec567 Merge branch 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm into next
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.

* 'for-linus' of git://ftp.arm.linux.org.uk/~rmk/linux-arm: (142 commits)

Linus Torvalds e5c4ecdc55 USB driver patches for 3.16-rc1
Here is the big USB driver pull request for 3.16-rc1.
 
 Nothing huge here, but lots of little things in the USB core, and in
 lots of drivers.  Hopefully the USB power management will be work better
 now that it has been reworked to do per-port power control dynamically.
 There's also a raft of gadget driver updates and fixes, CONFIG_USB_DEBUG
 is finally gone now that everything has been converted over to the
 dynamic debug inteface, the last hold-out drivers were cleaned up and
 the config option removed.  There were also other minor things all
 through the drivers/usb/ tree, the shortlog shows this pretty well.
 
 All have been in linux-next, including the very last patch, which came
 from linux-next to fix a build issue on some platforms.

Linus Torvalds 825f4e0271 ARM: SoC updates for 3.16 (part 1)
A quite large set of SoC updates this cycle. In no particular order:
 
 - Multi-cluster power management for Samsung Exynos, adding support for
   big.LITTLE CPU switching on EXYNOS5
 - SMP support for Marvell Armada 375 and 38x
 - SMP rework on Allwinner A31
 - Xilinx Zynq support for SOC_BUS, big endian
 - Marvell orion5x platform cleanup, modernizing the implementation and
   moving to DT.
 - _Finally_ moving Samsung Exynos over to support MULTIPLATFORM, so
   that their platform can be enabled in the same kernel binary as most
   of the other v7 platforms in the tree. \o/ The work isn't quite complete,
   there's some driver fixes still needed, but the basics now work.
 
 New SoC support added:
 - Freescale i.MX6SX
 - LSI Axxia AXM55xx SoCs
 - Samsung EXYNOS 3250, 5260, 5410, 5420 and 5800
 - STi STIH407
 
 Plus a large set of various smaller updates for different platforms. I'm
 probably missing some important one here.

 * The Qualcomm MSM platform is split out into legacy mach-msm and

Arnd Bergmann b25a7912eb ARM: msm: export legacy DMA interfaces
The msm_sdcc MMC driver and the msm_serial_hs uart driver both
use the pre-dmaengine interfaces provided by the MSM platform.

Since these drivers can be loadable modules, we should export
the functions used in the drivers.

Arnd Bergmann d967b0100f ARM: msm: avoid calling debug_ll_addr on !MMU
MSM7X00A has an open-coded version of debug_ll_io_init so it
can use MT_DEVICE_NONSHARED as required by the platform.

However, this fails to build on no-MMU kernels because the
debug_ll_addr function is not available. Since the iotable_init
function doesn't actually do anyting in this configuration,
we can simply get away by enclosing the broken function call
in an #ifdef, which seems to be the least ugly workaround.

This makes it easy to add SMP support for new devices by keying
on a device node for the release sequence. We add the
enable-method property for the cpus property to specify that we
want to use the gcc-msm8660 release sequence (which is going to
look for the global clock controller device node to map some
Scorpion specific power and control registers). We also remove
the nr_cpus detection code as that is done generically in the DT
CPU detection code.

Linus Torvalds 0ba3307a8e ARM: driver updates for 3.14
Updates of SoC-near drivers and other driver updates that makes more sense to
 take through our tree.
 
 The largest part of this is a conversion of device registration for some
 renesas shmobile/sh devices over to use resources. This has required
 coordination with the corresponding arch/sh changes, and we've agreed
 to merge the arch/sh changes through our tree.
 
 Added in this branch is support for Trusted Foundations secure firmware,
 which is what is used on many of the commercial Nvidia Tegra products
 that are in the market, including the Nvidia Shield. The code is local
 to arch/arm at this time since it's uncertain whether it will be shared
 with arm64 longer-term, if needed we will refactor later.
 
 A couple of new RTC drivers used on ARM boards, merged through our tree
 on request by the RTC maintainer.
 
 ... plus a bunch of smaller updates across the board, gpio conversions
 for davinci, etc.

Linus Torvalds 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

The DT based MSM platforms can join the multi-platform builds, so
introduce a DT based ARCH_MSM option. This option allows DT based
MSM platforms to be built into the multi-platform kernel. Also
introduce a hidden ARCH_MSM config that both the DT and non-DT
platform support code select to avoid churn in places that depend
on CONFIG_ARCH_MSM.

This branch contains code cleanups, moves and removals for 3.12.
 
 There's a large number of various cleanups, and a nice net removal of

 Highlights worth mentioning are:
 
 - A series of patches from Stephen Boyd removing the ARM local timer API.
 - Move of Qualcomm MSM IOMMU code to drivers/iommu.
 - Samsung PWM driver cleanups from Tomasz Figa, removing legacy PWM driver
   and switching over to the drivers/pwm one.
 - Removal of some unusued auto-generated headers for OMAP2+ (PRM/CM).
 
 There's also a move of a header file out of include/linux/i2c/ to
 platform_data, where it really belongs. It touches mostly ARM platform
 code for include changes so we took it through our tree.

names. Also simplify the code by assuming that clk_prepare_enable
and clk_disable_unprepare() will properly check for NULL pointers
(it will because MSM uses the common clock framework).
