The PMU module of Mali400 GPU is optional and it looks that it is not
present on Exynos4210, because any access to its registers causes external
abort. This patch removes "pmu" interrupt for Exynos4210 SoCs, so the
driver will skip the PMU module. This fixes following fault during kernel
boot:

The PMU module seems to work fine on Exynos4412 SoCs, so the patch also
moves the interrupt definitions to exynos4210.dtsi and exynos4412.dtsi
respectively, to keep only the common part in exynos4.dtsi.

Each CPU can (and does) participate in cooling down the system but the
DT only captures a handful of them, normally CPU0, in the cooling maps.
Things work by chance currently as under normal circumstances its the
first CPU of each cluster which is used by the operating systems to
probe the cooling devices. But as soon as this CPU ordering changes and
any other CPU is used to bring up the cooling device, we will start
seeing failures.
Also the DT is rather incomplete when we list only one CPU in the
cooling maps, as the hardware doesn't have any such limitations.
Update cooling maps to include all devices affected by individual trip
points.

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.

The Exynos4412 has the same watchdog as newer SoCs (e.g. Exynos5250).
Just like the others, for working it requires additional steps in Power
Management Unit: unmasking the reset request and enabling the system
reset. Without these additional steps in PMU, the watchdog will not be
able to reset the system on expiration event.
Change the compatible of Exynos4412 watchdog device node to
samsung,exynos5250-wdt which includes the additional PMU steps.
This will also fix infinite watchdog interrupt in soft mode (lack of

- TI eval board support for AM437x
- Allwinner A23 SoC, very similar to existing ones which mostly has
resulted in DT changes for support. Also includes support for an
Ippo tablet with the chipset.
- Allwinner A31 Hummingbird board support, not to be confused with
the SolidRun i.MX-based Hummingboard.
- Tegra30 Apalis board support"

This patch extends nodes of PMU system controller on Exynos4210, 4x12,
5250 and 5420 SoCs with newly defined properties used by Exynos CLKOUT
driver.

This patch cleans a arm-pmu node up for exynos4. Only exynos4412 series
boards have four pmu interrupts. Rest of exynos4 boards, except 4412, have only
two pmu interrupts. Thus, we can define two interrupts in the
exynos4.dtsi and extends the interrupts only exynos4412.dtsi.

Instead of hardcoding the SYSRAM details for each SoC,
pass this information through device tree (DT) and make
the code SoC agnostic. Generic DT SRAM bindings are
used for achieving this.

There is no need to use two cells for interrupt specifiers inside the
MCT interrupt map, so this patch simplifies the map to use one cell.

MCT is not an interrupt controller and so there is no point for device
tree nodes representing it to contain interrupt-controller
and #interrupt-cells properties.
