Power area A2VC0 was removed in revision ES2.0, cfr. R-Car Gen3 Hardware
User's Manual rev. 0.53E.
Hence remove it from the power area table when not running on ES1.x.
This is in line with the goal to:
1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
for now,
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
ubiquitous.

The same SoC may have different power areas, depending on SoC revision.
One option is to use different sets of power area tables for each SoC
revision. However, if the differences are small, it is much more
space-efficient to have a single set of tables, and fix those up at
runtime instead.
Hence provide a helper to NULLify power areas that do not exist on some
revisions (NULLified power areas are skipped during the registration
phase), and support for an optional initialization callback to e.g. fix
up power area tables.

The r8a7795 SYSC driver manages PM Domains, and thus is initialized from
an early_initcall(). However, this means the driver cannot check the
SoC revision, as the SoC device hasn't been registered yet.
Change renesas_soc_init() from a core_initcall() to an early_initcall()
to fix this (renesas-soc.o is listed before rcar-sysc.o in the Makefile).

On i.MX6QP, due to hardware erratum ERR009619, the PRE clocks may be
stalled during the power up sequencing of the PU power domain. As this
may lead to a complete loss of display output, the recommended
workaround is to keep the PU domain enabled during normal system
operation.
Implement this by rejecting the domain power down request on the
affected SoC.

Introduce a ti_sci_pm_domains driver to act as a generic pm domain
provider to allow each device to attach and associate it's ti-sci-id so
that it can be controlled through the TI SCI protocol.
This driver implements a simple genpd where each device node has a
phandle to the power domain node and also must provide an index which
represents the ID to be passed with TI SCI representing the device using
a single phandle cell. The driver manually parses the phandle to get the
cell value. Through this interface the genpd dev_ops start and stop
hooks will use TI SCI to turn on and off each device as determined by
pm_runtime usage.

Please note that Tegra186 does not support the flowctrl module, so
update the initialisation function such that we do not fall back and
attempt to map the 'hardcoded' address range for Tegra186. Furthermore
64-bit Tegra devices have always had the flowctrl node defined in their
device-tree and so only use the 'hardcoded' addresses for 32-bit Tegra
devices.

The flowctrl driver is required for both ARM and ARM64 Tegra devices
and in order to enable support for it for ARM64, move the Tegra flowctrl
driver into drivers/soc/tegra.
By moving the flowctrl driver, tegra_flowctrl_init() is now called by
via an early initcall and to prevent this function from attempting to
mapping IO space for a non-Tegra device, a test for 'soc_is_tegra()'
is also added.

The Makefiles currently controlling compilation of this code is:
drivers/soc/tegra/Makefile:obj-y += fuse/
drivers/soc/tegra/fuse/Makefile:obj-y += fuse-tegra.o
...meaning that it currently is not being built as a module by anyone.
Lets remove the couple traces of modularity so that when reading the
driver there is no doubt it is builtin-only.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Without providing the proper reg_defaults, the regmap registers first
read out may be always 0 if enabling cache, which results in the
following issue we met.
e.g. During driver probe in imx6_pm_domain_power_on():
regmap_read(pd->regmap, pd->reg_offs + GPC_PGC_PUPSCR_OFFS, &val);
The PGC_PUPSCR register val is always 0 but it's actually 0xf01 in HW.
Since GPC registers are tightly related to CPU bring up and may be
changed in bootloader, we don't want to provide defaults.
And the cache really does not save too much for GPC module.
Therefore, simply disable cache to fix the issue and make life easy.

The Exynos Power Management Unit (PMU) drivers contain quite large
static arrays of register values necessary for given Exynos SoC to enter
low power mode. All this data is useless for ARMv8 SoC like
Exynos5433, because the image will not be shared between ARMv7 and
ARMv8.
Add additional Kconfig symbol for selecting the SoC-specific driver
addons thus skipping the useless data in the final image (this is
similar approach to chosen for Exynos clock controller drivers):
- exynos-pmu driver will be compiled on both architectures ARMv7
and ARMv8,
- additional driver_data for ARMv7 SoCs will not be built on ARMv8
and a macro will return NULL for them in of_device_id - this should
be safe as these compatibles cannot match on ARMv7 and driver
anyway handles NULL driver_data,
- on ARMv8 compile only exynos-pmu driver which exposes the
syscon-regmap for PMU address space.

This is an almost complete re-write of the previous GPC power gating control
code found in the IMX architecture code. It supports both the old and the new
DT binding, allowing more domains to be added later and generally makes the
driver easier to extend, while keeping compatibility with existing DTBs.
As the result, all functionality regarding the power gating controller
gets removed from the IMX architecture GPC driver. It keeps only the
IRQ controller code in the architecture, as this is closely coupled to
the CPU idle implementation.

Driver updates for ARM SoCs.
A handful of driver changes this time around. The larger changes are:
- Reset drivers for hi3660 and zx2967
- AHCI driver for Davinci, acked by Tejun and brought in here due to
platform dependencies
- Cleanups of atmel-ebi (External Bus Interface)
- Tweaks for Rockchip GRF (General Register File) usage (kitchensink misc
register range on the SoCs)
- PM domains changes for support of two new ZTE SoCs (zx296718 and zx2967)

In the SoC branch we normally collect classic arch/arm/mach-* contents, i.e.
C code changes for SoC platforms. This release cycle the diffstat is quite
nice, in that we're removing 3x the amount of code that's being added.
The main reason for this is that there's a removal of camera drivers for
Freescale i.MX chips (driver was removed so the device registration isn't
needed any more). There's also removal of display initialization code for OMAP
that is no longer needed.
The rest are mostly minor tweaks and cleanups; constification on Samsung
platforms, cleanup of ux500 platform data, purge of other unused platform
data/device seutp on i.MX and other good stuff.
New SoC support this cycle is for two Allwinner platforms, H2+ and V3s.

Merge tag 'omap-for-v4.11/drivers-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers
Just a single wkup_m3_ipc clean-up for v4.11 merge window.
We don't currently have anything else for drivers/soc to
merge, but I'd expect that to change as soon as we can start
moving PM code into drivers with the recently posted SRAM
changes. Anyways, sent as a separate pull request to make
it easy to group the ARM SoC pull requests.
