56c126e87e ARM: dts: exynos: Rename SysRAM node to "sram"
The device node name should reflect generic class of a device so rename
the SysRAM node from "sysram" to "sram".  The child nodes stay as before
as "smp-sysram" to match their real purpose.  This will be also in sync
with upcoming DT schema.  No functional change.

672f33198b arm: dts: exynos: Add missing cooling device properties for CPUs
The cooling device properties, like "#cooling-cells" and
"dynamic-power-coefficient", should either be present for all the CPUs
of a cluster or none. If these are present only for a subset of CPUs of
a cluster then things will start falling apart as soon as the CPUs are
brought online in a different order. For example, this will happen
because the operating system looks for such properties in the CPU node
it is trying to bring up, so that it can register a cooling device.

Add such missing properties.

Fix other missing properties (clocks, OPP, clock latency) as well to
make it all work.

387720c938 ARM: DTS: Fix register map for virt-capable GIC
Since everybody copied my own mistake from the DT binding example,
let's address all the offenders in one swift go.

Most of them got the CPU interface size wrong (4kB, while it should
be 8kB), except for both keystone platforms which got the control
interface wrong (4kB instead of 8kB).

In a few cases where I knew for sure what implementation was used,
I've added the "arm,gic-400" compatible string. I'm 99% sure that
this is what everyone is using, but short of having the TRM for
all the other SoCs, I've left them alone.

 in a way that only provides compatibility with old DT blobs on new

 are based on top of the driver changes and are now in this branch.
 
 For NXP i.MX and Samsung Exynos, the changes in here depend on
 other changes that got merged through the clk maintainer tree.

5c73cc4b6c ARM: DT updates for v4.1
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).

8b283c0254 ARM: exynos4/5: convert pmu wakeup to stacked domains
Exynos has been (ab)using the gic_arch_extn to provide
wakeup from suspend, and it makes a lot of sense to convert
this code to use stacked domains instead.

This patch does just this, updating the DT files to actually
reflect what the HW provides.

BIG FAT WARNING: because the DTs were so far lying by not
exposing the fact that the PMU block is actually the first
interrupt controller in the chain for RTC, kernels with this patch
applied wont have any suspend-resume facility when booted
with old DTs, and old kernels with updated DTs may not even boot.

Also, I strongly suspect that there is more than two wake-up
interrupts on these platforms, but I leave it to the maintainers
to fix their mess.

Use assigned-clocks/assigned-clock-parents properties for
CMU clock controller DT node to secure proper clock setup:
switching the two muxes to root oscillator clock is not only
required for proper powering down the ISP power domain,
but it also reduces the risk of accessing the ISP CMU
registers while the ISP power domain remains turned off
(i.e. through the common clock framework by clk_summary)
