c9cbfd623d ARM: dts: exynos: Add opp-suspend to DMC and leftbus devfreq OPPs on Exynos4
Mark as opp-suspend required devfreq Operating Performance Points to
fix resuming issues on Exynos 4 boards.

The patch is based on earlier work by Tobias Jakobi.

670734f558 ARM: dts: exynos: Add all CPUs in cooling maps
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.

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.

edef4285af ARM: dts: exynos/s3c: Remove leading 0x and 0s from bindings notation
Improve the DTS files by removing all the leading "0x" and zeros to fix the
following dtc warnings:

    Warning (unit_address_format): Node /XXX unit name should not have leading "0x"
    Warning (unit_address_format): Node /XXX unit name should not have leading 0s

Converted using the following command:

    find arch/arm/boot/dts -type f \( -iname "*.dts" -o -iname "*.dtsi" \) -exec sed -i \
    -e "s/@\([0-9a-fA-FxX\.;:#]\+\)\s*{/@\L\1 {/g" -e "s/@0x\(.*\) {/@\1 \
    {/g" -e "s/@0\+\(.\+\) {/@\1 {/g" {} +

For simplicity, two sed expressions were used to solve each warnings separately.

To make the regex expression more robust a few other issues were resolved,
namely setting unit-address to lower case, and adding a whitespace before the
the opening curly brace: https://elinux.org/Device_Tree_Linux#Linux_conventions

This will solve also a side effect warning:

    Warning (simple_bus_reg): Node /XXX@<UPPER> simple-bus unit address format error, expected "<lower>"

This is a follow up to commit 4c9847b737 ("dt-bindings: Remove leading 0x from bindings notation")

bdc42353ba ARM: dts: exynos: Fix watchdog reset on Exynos4412
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
interrupt clear) because it is also included in samsung,exynos5250-wdt.

bb9055b274 ARM: late Exynos multiplatform changes
These continue the multiplatform support for exynos, adding support
 for building most of the essential drivers (clocksource, clk, irqchip)
 when combined with other platforms. As a result, it should become
 really easy to add full multiplatform exynos support in 3.11, although
 we don't yet enable it for 3.10.
 
 The changes were not included in the earlier multiplatform series
 in order to avoid clashes with the other Exynos updates.
 
 This also includes work from Tomasz Figa to fix the pwm clocksource
 code on Exynos, which is not strictly required for multiplatform,
 but related to the other patches in this set and needed as a bug
 fix for at least one board.

662478d060 ARM: dts: add mshc controller node for Exynos4x12 SoCs
Commit 800974ac ("ARM: dts: Add board dts file for ODROID-X") includes a node
to describe the board level properties for mshc controller. But the mshc
controller node was not added in the Exynos4x12 dtsi file which resulted
in the following warning when compiling the dtb files.

Warning (reg_format): "reg" property in /mshc@12550000/slot@0 has invalid length (4 bytes) (#address-cells == 2, #size-cells == 1)
Warning (avoid_default_addr_size): Relying on default #address-cells value for /mshc@12550000/slot@0
Warning (avoid_default_addr_size): Relying on default #size-cells value for /mshc@12550000/slot@0

Fix this by adding the mshc controller node for Exynos4x12 SoCs.
