d7da1ccfa2 ARM: i.MX: remove map_io callback
There is no need to define map_io only for debug_ll_io_init() since it
is already called in devicemaps_init() if map_io is NULL.

Apart from that, for NOMMU build debug_ll_io_init() is a nop which
leads to following error:

CC      arch/arm/mach-imx/mach-imx1.o
arch/arm/mach-imx/mach-imx1.c:40:13: error: 'debug_ll_io_init' undeclared here (not in a function)
  .map_io  = debug_ll_io_init,
             ^

a051f220d6 ARM/imx/mmcd: Fix broken cpu hotplug handling
The cpu hotplug support of this perf driver is broken in several ways:

1) It adds a instance before setting up the state.

2) The state for the instance is different from the state of the
   callback. It's just a randomly chosen state.

3) The instance registration is not error checked so nobody noticed that
   the call can never succeed.

4) The state for the multi install callbacks is chosen randomly and
   overwrites existing state. This is now prevented by the core code so the
   call is guaranteed to fail.

5) The error exit path in the init function leaves the instance registered
   and then frees the memory which contains the enqueued hlist node.

6) The remove function is removing the state and not the instance.

Fix it by:

- Setting up the state before adding instances. Use a dynamically allocated
  state for it.

- Installing instances after the state has been set up

- Removing the instance in the error path before freeing memory

- Removing the instance not the state in the driver remove callback

While at is use raw_cpu_processor_id(), because cpu_processor_id() cannot
be used in preemptible context, and set the driver data after successful
registration of the pmu.

e79ab194d1 ARM: SoC platform updates for v4.10
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - Added support for the TI DRA71x family of SoCs in mach-omap2,
   this is an new variant of the the DRA72x/DRA74x automotive
   infotainment chips we already supported for a while.
 
 - Added support for the ST STM32F746 SoC, the first Cortex-M7
   based microcontroller we support, related to the smaller
   STM32F4 family.
 
 - Renesas adds support for r8a7743 and r8a7745 in mach-shmobile,
   see http://elinux.org/RZ-G
 
 - SMP is now supported on the OX820 platform
 
 - A lot of code in mach-omap2 gets removed as a follow-up to
   removing support for board files in the previous release
 
 - Davinci has some new work to improve USB support
 
 - For i.MX, the performance monitor now supports profiling the
   memory controller using 'perf'
 
 Conflicts:
 arch/arm/mach-shmobile/setup-rcar-gen2.c: rcar_gen2_clocks_init()
 is gone, calling of_clk_init(NULL) is sufficient now.

3ec5e8d82b ARM: SoC non-urgent fixes for v4.10
As usual, we queue up a few fixes that don't seem urgent enough to go in
 through -rc, or that just came a little too late given their size.
 
 The zx fixes make the platform finally boot on real hardware, the
 davinci and imx31 get the DT support working better for some of
 the machines that are still normally used with classic board files.
 One tegra fix is important for new bootloader versions, but the
 bug has been around for a while without anyone noticing.
 
 The other changes are mostly cosmetic.

8478132a87 Revert "arm: move exports to definitions"
This reverts commit 4dd1837d75.

Moving the exports for assembly code into the assembly files breaks
KSYM trimming, but also breaks modversions.

While fixing the KSYM trimming is trivial, fixing modversions brings
us to a technically worse position that we had prior to the above
change:

- We end up with the prototype definitions divorsed from everything
  else, which means that adding or removing assembly level ksyms
  become more fragile:
  * if adding a new assembly ksyms export, a missed prototype in
    asm-prototypes.h results in a successful build if no module in
    the selected configuration makes use of the symbol.
  * when removing a ksyms export, asm-prototypes.h will get forgotten,
    with armksyms.c, you'll get a build error if you forget to touch
    the file.

- We end up with the same amount of include files and prototypes,
  they're just in a header file instead of a .c file with their
  exports.

As for lines of code, we don't get much of a size reduction:
 (original commit)
 47 files changed, 131 insertions(+), 208 deletions(-)
 (fix for ksyms trimming)
 7 files changed, 18 insertions(+), 5 deletions(-)
 (two fixes for modversions)
 1 file changed, 34 insertions(+)
 3 files changed, 7 insertions(+), 2 deletions(-)
which results in a net total of only 25 lines deleted.

As there does not seem to be much benefit from this change of approach,
revert the change.

Instead of returning of_genpd_add_provider_onecell() directly,
we should check its return value and in the case of error we
should unwind the previously taken actions, which in these case are:
- Call imx6q_pm_pu_power_off()
- Set imx6q_pu_domain.reg back to NULL

Setting imx6q_pu_domain.reg to NULL in the error case is important
as it will prevent further operations in the pu_reg regulator.

This kernel crash is not observed with imx_v6_v7_defconfig because
it selects GPU and VPU drivers, which are consumers of the GPC block
and thus change the refcount of the pu_reg regulator.

imx-gpc: probe of 20dc000.gpc failed with error -22

The gpc probe fails because of_genpd_add_provider_onecell() now checks
if all the domains are initialized via pm_genpd_present() function
and it fails because not all the power domains are initialized.

In order to fix this error, initialize all the power domains from
imx_gpc_domains[], not only the imx6q_pu_domain.base one.

Pull kbuild updates from Michal Marek:

 - EXPORT_SYMBOL for asm source by Al Viro.

   This does bring a regression, because genksyms no longer generates
   checksums for these symbols (CONFIG_MODVERSIONS). Nick Piggin is
   working on a patch to fix this.

   Plus, we are talking about functions like strcpy(), which rarely
   change prototypes.

 - Fixes for PPC fallout of the above by Stephen Rothwell and Nick
   Piggin

 - fixdep speedup by Alexey Dobriyan.

 - preparatory work by Nick Piggin to allow architectures to build with
   -ffunction-sections, -fdata-sections and --gc-sections

 - CONFIG_THIN_ARCHIVES support by Stephen Rothwell

 - fix for filenames with colons in the initramfs source by me.

66f2c6d952 ARM: SoC platform updates for v4.9
These are updates for platform specific code on 32-bit ARM machines,
 essentially anything that can not (yet) be expressed using DT files.
 
 Noteworthy changes include:
 
 - We get support for running in big-endian mode on two platforms:
   sunxi (Allwinner) and s3c24xx (old Samsung).
 
 - The recently added Uniphier platform now uses standard PSCI
   methods for SMP booting and we remove support for old bootloader
   versions that did not support it yet.
 
 - In sunxi, we gain support for the "Nextthing GR8" SoC, which
   is a close relative of the Allwinner A13 and R8 chips.
 
 - PXA completes its move over to the generic dmaengine framework
   and removes its old private API
 
 - mach-bcm gains support for BCM47189/BCM53573, their first ARM
   SoC with integrated 802.11ac wireless networking.

a771151a83 ARM: SoC cleanups for v4.9
The cleanups for v4.9 are a little larger that usual, but thankfully
 that is almost exclusively due to removing a significant number of
 files that have become obsolete after the still ongoing conversion
 of old board files to devicetree.
 
 - for mach-omap2, which is still the largest platform in arch/arm/,
   the conversion to DT is finally complete after the Nokia N900 is
   now fully supported there, along with the omap3 LDP, and we can
   remove those two board files.
   If no regressions are found, another large cleanup for the platform
   will happen as a follow-up, removing dead code and restructuring
   the platform based on being DT-only.
 
 - In mach-imx, similar work is ongoing, but has not come that far.
   This time, we remove the obsolete board file for the i.MX1
   generation, which like i.MX25, i.MX5, i.MX6, and i.MX7 is now DT-only.
   The remaining board files are for i.MX2 and i.MX3 machines
   based on old ARM926 or ARM1136 cores that should work with DT
   in principle.
 
 - realview has just been converted from board files to DT, and a lot
   of code gets removed in the process. This is the last
   ARM/Keil/Versatile derived platform that was still using board
   files, the other ones being integrator, versatile and vexpress.
   We can probably merge the remaining code into a single directory
   in the near future.
 
 - clps711x had completed the conversion in v4.8, but we accidentally
   left the files in place that should have been deleted then.
 
 Conflicts: two files deleted here have been modified upstream,
 the changes can be discarded.

e13688fe61 ARM: select PCI_DOMAINS config from ARCH_MULTIPLATFORM
PCI_DOMAINS config should be selected for any SoCs
having more than a single PCIe controller. Without PCI_DOMAINS
config, only one PCIe controller gets registered.

Select PCI_DOMAINS in ARCH_MULTIPLATFORM if PCI is selected, since
it doesn't harm even if a platform has a single PCIe port.
Also remove PCI_DOMAINS being selected from other platform
specific configs.

8aade778f7 ARM: imx6: add missing BM_CLPCR_BYPASS_PMIC_READY setting for imx6sx
i.MX6SX has bypass PMIC ready function, as this function
is normally NOT enabled on the board design, so we need
to bypass the PMIC ready pin check during DSM mode resume
flow, otherwise, the internal DSM resume logic will be
waiting for this signal to be ready forever and cause
resume fail.

547e8f5269 ARM: imx: add cpuidle support for i.mx6ul
This patch enables cpuidle driver for i.MX6UL, it
reuses i.MX6SX's cpuidle driver, 3 levels of cpuidle
supported:

1. ARM WFI;
2. SOC in WAIT mode;
3. SOC in WAIT mode + ARM power off.

As i.MX6UL has cortex-A7 CORE with an internal L2
cache, so flushing it before powering down ARM platform
is necessary, flush_cache_all() in last step of cpu_suspend
has very small overhead, just call it to avoid cache
type check for different platforms.

The IS_ENABLED() macro checks if a Kconfig symbol has been enabled either
built-in or as a module, use that macro instead of open coding the same.

Using the macro makes the code more readable by helping abstract away some
of the Kconfig built-in and module enable details.
