Add support for the A4R power domain, and hook up the A3RV subdomain,
and the CEU0, TMU0, and IIC0 hardware blocks.
This domain also contains the Realtime CPU (SH-4A), Realtime CPU debug
modules, H-UDI, RT-SHwy, INTCS, RT-HPB, VIO6C, JPU, RTDMAC1/2, SSP,
MSIOF0, CMT0, ICB, DREQPAK (RT), 2DDMAC, IPMMUI, and 2DG hardware
blocks, but these are currently not used by any driver.

Add support for the D4 power domain.
This domain contains the Coresight-ETM hardware block.
As long as the ARM debug/perf code doesn't use resource management with
runtime PM support, the D4 power domain must be kept powered to avoid a
crash during resume from s2ram (dbg_cpu_pm_notify() calls
reset_ctrl_regs() unconditionally, causing an undefined instruction
oops).

Commit 68f3b875f7848f5304472184a4634148c5330cbd
"ARM: integrator: make the Integrator multiplatform"
broke allmodconfig like this:
>> arch/arm/include/asm/cmpxchg.h:114:2: error: #error
"SMP is not supported on this platform"
(etc)
This is due to the fact that as we turned on multiplatform
for the Integrator, this enabled a lot of non-applicable
CPU's to be selected for its multiplatform images, due to
a lot of "depends on ARCH_INTEGRATOR" restrictions in
arch/arm/mm/Kconfig for the different ARM CPU types.
Fix this by restricting the CPU selections to respective
multiplatform config, which now becomes a subset of the
possible Integrator configurations, or alternatively the
non-multiplatform config plus ARCH_INTEGRATOR, i.e.:
if (!ARCH_MULTIPLATFORM || ARCH_MULTI_Vx) &&
(ARCH_INTEGRATOR || ARCH_FOO ...)
Since the Integrator has been converted to multiplatform,
this will often take the short form:
if (ARCH_MULTI_Vx && ARCH_INTEGRATOR)
If no other non-multiplatform platforms are elegible.

The ux500 SoC uses the generic PM domain and requires the domains to be
specified through DT.
Currently the genpd callbacks for handling power gating|ungating are
implemented as dummy functions. To be able to enable those to perform
PM domain gating/ungating, each device that resides in the VAPE domain
must be properly handled from a runtime PM perspective.

"ARM: EXYNOS: Add support for firmware-assisted suspend/resume" patch
added to arch/arm/mach-exynos/firmware.c new references to functions
from arch/arm/mach-exynos/sleep.S causing the new CONFIG_PM_SLEEP=n
build breakages. Then "ARM: EXYNOS: Fix build with PM_SLEEP=n and
ARM_EXYNOS_CPUIDLE=y" patch tried to fix the CONFIG_PM_SLEEP=n issues
by always building sleep.S which caused the CONFIG_ARM_CPU_SUSPEND=n
build breakage. Fix it by building arch/arm/mach-exynos/sleep.o only
for CONFIG_EXYNOS_CPU_SUSPEND=y and adding appropriate IS_ENABLED()
checks to arch/arm/mach-exynos/firmware.c.

Register cpuidle platform device on Exynos4x12 SoCs allowing EXYNOS
cpuidle driver usage on these SoCs.
AFTR mode reduces power consumption on Trats2 board (Exynos4412 SoC
with secure firmware enabled) by ~12% when EXYNOS cpuidle driver is
enabled (in both cases the default exynos_defconfig config is used
and CPU1-3 are offlined).
Currently Exynos4412 SoC support is limited to Trats2 board.

Add S5P_CENTRAL_SEQ_OPTION register setup to cpuidle AFTR mode code
by moving the relevant code from exynos_pm_suspend() (used only by
suspend) to exynos_pm_central_suspend() (used by both suspend and
AFTR). Without this setup AFTR mode doesn't show any benefit over
WFI one (at least on Exynos4412 SoC). When this setup is applied
AFTR mode reduces power consumption by ~12% (as measured on Trats2
board).
This change is a preparation for adding secure firmware support to
EXYNOS cpuidle driver.

On some platforms (i.e. EXYNOS ones) more than one idle mode is
available and we need to distinguish them in firmware do_idle method.
Add mode parameter to do_idle firmware method and AFTR mode support
to EXYNOS do_idle implementation.
This change is a preparation for adding secure firmware support to
EXYNOS cpuidle driver.
This patch shouldn't cause any functionality changes.

On a numer of Exynos-based boards Linux kernel is running in non-secure
mode under a secure firmware. This means that certain operations need to
be handled in special way, with firmware assistance. System-wide
suspend/resume is an example of such operations.
This patch adds support for firmware-assisted suspend/resume by
leveraging recently introduced suspend and resume firmware operations
and modifying existing suspend/resume paths to account for presence of
secure firmware.

This patch extends the firmware_ops structure with two new callbacks:
.suspend() and .resume(). The former is intended to ask the firmware to
save all its volatile state and suspend the system, without returning
back to the kernel in between. The latter is to be called early by
very low level platform suspend code after waking up to restore low
level hardware state, which can't be restored in non-secure mode.
While at it, outdated version of the structure is removed from the
documentation and replaced with a reference to the header file.

Merge "ARM: brcmstb: SMP, Kconfig, earlyprintk and GISB fixes" from Florian
Fainelli:
This pull request contains 3 changes for the brcmstb platform and 2 changes
to the GISB bus arbiter driver
- fist patch adds earlyprintk to brcmstb platforms using the existing 8250
infrastructure
- second patch re-introduces SMP support after fixing the problems we had in
the initial implementation, for this patch to apply cleanly, I had to advance
up to "ARM: brcmstb: revert SMP support"
- third patch is dropping unused Kconfig dependencies
- fourth patch registers the ARM fault code for external aborts that the GISB
bus arbiter driver is designed to assit
- fifth patch does save/restore the GISB arbiter timeout across S3
suspend/resume cycles
Thanks!

Support for SMP bringup of the B15 CPUs on Broadcom STB chips was added
in commit 4fbe66d9903425156c193ae44c81c0f7557755c4 but was reverted in
commit fc3e825fa91636a5d1b992e769b2d8279877bfad to address some late
review comments. This reintroduces SMP support.

Pull ARM SoC cleanups from Arnd Bergmann:
"The remaining cleanups for 3.19 are to a large part result of
devicetree conversion nearing completion on two other platforms
besides AT91:
- Like AT91, Renesas shmobile is in the process to migrate to DT and
multiplatform, but using a different approach of doing it one SoC
at a time. For 3.19, the r8a7791 platform and associated "Koelsch"
board are considered complete and we remove the non-DT
non-multiplatform support for this.
- The ARM Versatile Express has supported DT and multiplatform for a
long time, but we have still kept the legacy board files around,
because not all drivers were fully working before. We have finally
taken the last step to remove the board files.
Other changes in this branch are preparation for the later branches or
just unrelated to the more interesting changes:
- The dts files for arm64 get moved into per-vendor directories for a
clearer structure.
- Some dead code removal (zynq, exynos, davinci, imx)
- Using pr_*() macros more consistently instead of printk(KERN_*) in
some platform code"

The MMCI driver, when used with a Device Tree described device, relies
on the "vmmc" voltage regulator supply to set the OCR register voltage bits,
using MMC core's mmc_regulator_get_supply() function.
Without the regulator framework present there are no valid operating
voltages reported and the device initialisation fails:
mmci-pl18x 10005000.mmci: No vmmc regulator found
mmci-pl18x 10005000.mmci: no support for card's volts
mmc0: error -22 whilst initialising SD card
