Pull ARM SoC multiplatform code changes from Olof Johansson:
"The changes here belong to two main platforms:
- Atmel At91 is flipping the bit and going multiplatform. This
includes some cleanups and removal of code, and the final flip of
config dependencies
- Shmobile has several platforms that are going multiplatform, but
this branch also contains a bunch of cleanups that they weren't
able to keep separate in a good way. THere's also a removal of one
of their SoCs and the corresponding boards (sh7372 and mackerel)"

Add a device node for the System Controller, with subnodes that
represent the hardware power area hierarchy.
Hook up all devices to their respective PM domains.
Note that unlike on R-Mobile A1 (r8a7740), PM domain D4 can be powered
down without ill effects on s2ram behavior, just like on SH-Mobile AP4
(sh7372). Hence we can postpone adding a (minimal) device node for the
Coresight-ETM hardware block.
The System Controller is also used by the R-Mobile Reset driver, which
can now restart the system.

Add a node for the Private Timer and Watchdog, as found in the Cortex-A9
MPCore.
Without this, there's no clocksource available during early kernel
initialization, before cmt1 is initialized, leading to a lock-up if
CONFIG_CPU_IDLE=y.

Move the Ethernet node from the root of the device tree to the BSC node,
as it's connected to the Bus State Controller. This allows the system
to know the right position of the Ethernet node in the clock and PM
domain hierarchy, and manage the clock and PM domain appropriately.
Also rename the node's name from "lan9220" to "ethernet", to conform to
ePAPR generic name recomendations.

Add a device node for the System Controller, with subnodes that
represent the hardware power area hierarchy.
Hook up all devices to their respective PM domains.
Add a minimal device node for the Coresight-ETM hardware block, and
hook it up to the D4 PM domain, so the R-Mobile System Controller
driver can keep the domain powered, until the new Coresight code
handles runtime PM.
The System Controller is also used by the R-Mobile Reset driver, which
can now restart the system.

Currently the pin function controller (which is also a GPIO controller)
is instantiated before the interrupt controllers due to the order in the
DTS. At that time, the irq domains for the interrupt controllers
referenced by its interrupts-extended property cannot be found yet:
irq: no irq domain found for /interrupt-controller@e61c0000 !
Nevertheless, the core OF probing code ignores this failure, besides a
debug message that's not normally printed:
not all legacy IRQ resources mapped for pfc
and continues initialization of the device. Then, the sh-pfc driver
cannot find any IRQ resources, and thinks no interrupts are available,
causing gpio-keys to fail later:
gpio-keys keyboard: Unable to claim irq 0; error -22
gpio-keys: probe of keyboard failed with error -22
Move the pin function controller node after the interrupt controller
nodes it references to work around the bug in the core OF probing code.

of converting all of mach-shmobile to be multiplatform capable,
as adding pinctrl and common-clock support for it would be more
work than it's worth. As always, should any legitimate upstream
users show up in the future, we will revert this removal]

Pull ARM SoC driver updates from Olof Johansson:
"Driver updates for v4.1. Some of these are for drivers/soc, where we
find more and more SoC-specific drivers these days. Some are for
other driver subsystems where we have received acks from the
appropriate maintainers.
The larger parts of this branch are:
- MediaTek support for their PMIC wrapper interface, a high-level
interface for talking to the system PMIC over a dedicated I2C
interface.
- Qualcomm SCM driver has been moved to drivers/firmware. It's used
for CPU up/down and needs to be in a shared location for arm/arm64
common code.
- cleanup of ARM-CCI PMU code.
- another set of cleanusp to the OMAP GPMC code"

it as a syscon to be able to get a regmap.
Also declare it as a simple-mfd and its watchdog subnode.
Finally, document the watchdog compatible string.

"As always, this tends to be one of our bigger branches. There are
lots of updates this release, but not that many jumps out as something
that needs more detailed coverage. Some of the highlights are:
- DTs for the new Annapurna Labs Alpine platform
- more graphics DT pieces falling into place on Exynos, bridges,
clocks.
- plenty of DT updates for Qualcomm platforms for various IP blocks
- some churn on Tegra due to switch-over to tool-generated pinctrl
data
- misc fixes and updates for Atmel at91 platforms
- various DT updates to add IP block support on Broadcom's Cygnus
platforms
- more updates for Renesas platforms as DT support is added for
various IP blocks (IPMMU, display, audio, etc)"

All Marvell EBU SoCs (Kirkwood, Dove, Orion, Armada) have the
capability of changing the location of their internal registers (i.e
the registers for most hardware blocks inside the SoC). When coming
out of reset, the internal registers are mapped at 0xd0000000, but
since years and years, the tradition has been to have the internal
registers remapped at 0xf1000000 by the bootloader, and Linux has
since then assumed that the internal registers for the SoC were
located at 0xf1000000 on Kirkwood, Dove, Orion, etc. Linux has never
been aware that those registers are remappable (and there is no way to
know where they are mapped at runtime, since the register to configure
the address of the registers is itself within the internal registers).
Then came the Armada 370 and Armada XP, in which some of the very
early silicon steppings had an issue, which forced to use 0xd0000000:
the SoC was no longer working properly when the internal registers
were remapped at 0xf1000000. This issue is only affecting very early
silicon steppings and production steppings are not affected: the issue
has been fixed in between.
Since what we (Free Electrons) used to do the initial submission of
the Armada 370 and Armada XP platforms was evaluation boards with
those very early steppings, we submitted Device Tree that assumed the
internal registers were mapped at 0xd0000000. This is the case for
Armada 370 DB, Armada XP DB and Armada XP GP.
However, in practice, since Marvell has been shipping the evaluation
boards with production steppings of the SoC, they are shipping those
boards with bootloaders that remap the registers to 0xf1000000. We
have already changed this internal register address to 0xf1000000 for
the Armada XP DB in commit 82066bdb5a75 and for the Armada XP GP in
commit 91ed32200e6e (both merged in v3.15).
We only recently got our hand on an Armada 370 DB with a production
stepping of the SoC, which uses a bootloader that remaps internal
registers at 0xf1000000. Therefore, this commit aligns the Armada 370
DB to be like the Armada XP DB and Armada XP GP: assume that the
internal registers are mapped at 0xf1000000.
We would like to stress out the fact that the usage of 0xd0000000 as
the internal register base address was a temporary workaround for
early steppings deficiencies, and that the real long-term solution is
the usage of 0xf1000000. Having 0xd0000000 is an *accident* in the
life of the Marvell platform support in the kernel, as is confirmed by
the usage of 0xf1000000 in all previous Marvell platforms (Dove,
Kirkwood, Orion).
There are unfortunately a number of commercial devices that continue
to use 0xd0000000 even though they use production steppings of the
SoC, simply because the vendors of such devices have never bothered
using a more recent bootloader version from Marvell. There is not much
we can do about it, and we plan on keeping 0xd0000000 in the Device
Tree of such devices.
The main reason for remapping the internal registers at 0xf1000000
instead of 0xd0000000 is that it leaves more space in the 0 -> 4 GB
part of the physical address space for RAM. With registers at
0xd0000000, all RAM between 0xd0000000 to 0xffffffff is lost because
it's covered by the I/O registers.

HS400 timing values are added for SMDK5420, exynos5420-peach-pit
and exynos5800-peach-pi boards. This also adds RCLK GPIO line,
this gpio should be in pull-down state.
This also enables HS400 on peach-pi and this updates the clock
frequency to 800MHz to be set as input clock to controller.
