551ed9b8c3 ARM: dts: exynos: Add mem-2-mem Scaler devices
There are 3 scaler devices in Exynos5420 SoCs, all are a part of MSCL
power domain. MSCL power domain and SYSMMU controllers (two per each
scaler device) have been already added to exynos5420.dtsi earlier,
so bind them to newly added devices.

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")

28928a3ce1 ARM: dts: exynos: Do not ignore real-world fuse values for thermal zone 0 on Exynos5420
In Odroid XU3 Lite board, the temperature levels reported for thermal
zone 0 were weird. In warm room:
	/sys/class/thermal/thermal_zone0/temp:32000
	/sys/class/thermal/thermal_zone1/temp:51000
	/sys/class/thermal/thermal_zone2/temp:55000
	/sys/class/thermal/thermal_zone3/temp:54000
	/sys/class/thermal/thermal_zone4/temp:51000

Sometimes after booting the value was even equal to ambient temperature
which is highly unlikely to be a real temperature of sensor in SoC.

The thermal sensor's calibration (trimming) is based on fused values.
In case of the board above, the fused values are: 35, 52, 43, 58 and 43
(corresponding to each TMU device).  However driver defined a minimum value
for fused data as 40 and for smaller values it was using a hard-coded 55
instead.  This lead to mapping data from sensor to wrong temperatures
for thermal zone 0.

Various vendor 3.10 trees (Hardkernel's based on Samsung LSI, Artik 10)
do not impose any limits on fused values.  Since we do not have any
knowledge about these limits, use 0 as a minimum accepted fused value.
This should essentially allow accepting any reasonable fused value thus
behaving like vendor driver.

The exynos5420-tmu-sensor-conf.dtsi is copied directly from existing
exynos4412 with one change - the samsung,tmu_min_efuse_value.

The conventions is to put SoC devices under 'soc' node. In fact other
our DTSes (like exynos3250.dtsi or exynos5410.dtsi) already follow it.
Adjust exynos5250 and exynos5420 DTSI to follow this convention. This is
also necessary for the upcoming change in exynos5410.dtsi to inherit
from common exynos5.dtsi.

94aed538e0 ARM: dts: exynos: Add async-bridge clock to MFC power domain for Exynos5420
The MFC IP is also inter-connected by an Async-Bridge so the CLK_ACLK333
has to be ungated during a power domain switch. Trying to do it when the
clock is gated will fail and lead to an imprecise external abort error
when the driver tries to access the MFC registers with the PD disabled.

For example, if the s5p-mfc module is removed and the MFC PD turned off:

[  186.835606] Power domain power-domain@10044060 disable failed
[  186.835671] s5p-mfc 11000000.codec: Removing 11000000.codec

And when the module is inserted again:

4f0d20ec19 ARM: dts: Make CPU configuration more readable on exynos542x/5800
Exynos5420 and Exynos5800 boards boot from big core (A15) but
Exynos5422 boards choose otherwise: LITTLE core (A7) (on Exynos5422 this
is property of the board - configurable by pulling up/down gpg2-1).
To make user-visible CPU ordering more consistent the 'cpus' node was
overridden by exynos5422-cpus.dtsi.

However this is a little bit ugly and error-prone. Overriding the CPU
child nodes requires to basically reverse what was done initially in
exynos5420.dtsi.

Instead, split CPU configuration entirely to separate files which should
be included by board DTS.

c07f827011 ARM: dts: Include exynos5420-pinctrl after the nodes were defined for exynos5420
The dtc compiler combines all the defined nodes that have the same path
so a device node definition can be in one file and later be extended in
another one.

That's the case of the Exynos5420 pinctrl device nodes that are defined
in the exynos5420.dtsi file and extended in exynos5420-pinctrl.dtsi.

But since the exynos5420.dtsi file includes the exynos5420-pinctrl.dtsi
before the pinctrl device nodes are actually defined, the definition of
the pinctrl device nodes happens in exynos5420-pinctrl.dtsi and are
extended in exynos5420.dtsi.

That is the opposite of the original intention so even when there is no
difference in practice, the exynos5420-pinctrl.dtsi include should be
moved at the end of the exynos5420.dtsi file after the pinctrl device
nodes have been already defined.

This will also allow to later change the exynos5420-pinctrl.dtsi file
to use labels instead of full paths to extend the pinctrl nodes. Since
keeping the include at the top, would cause a dtc build error due the
pinctrl labels not being defined yet.
