On Exynos5422/5800 the regulator supply for the A15 cores ("vdd_arm") is
coupled with the regulator supply for the SoC internal circuits
("vdd_int"), thus all operating points that modify one of those supplies
have to specify a triplet of the min/target/max values to properly work
with regulator coupling.

Fix up inconsistent usage of upper and lowercase letters in "Samsung"
and "Exynos" names.
"SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked
names. Therefore they should be written with lowercase letters starting
with capital letter.
The lowercase "Exynos" name is promoted by its manufacturer Samsung
Electronics Co., Ltd., in advertisement materials and on website.
Although advertisement materials usually use uppercase "SAMSUNG", the
lowercase version is used in all legal aspects (e.g. on Wikipedia and in
privacy/legal statements on
https://www.samsung.com/semiconductor/privacy-global/).

Add missing 2.0GHz, 1.9GHz & 1.8GHz OPPs (for A15 cores) and 1.4GHz
OPP (for A7 cores). Also update common Odroid-XU3 Lite/XU3/XU4
thermal cooling maps to account for new OPPs.
Since some new OPPs are not available on all Exynos5422/5800 boards
modify dts files for Odroid XU3 Lite (limited to 1.8 GHz / 1.3 GHz) &
Peach Pi (limited to 2.0 GHz / 1.3 GHz) accordingly.
This patch uses maximum voltages for new OPPs. This is a temporary
solution till proper Exynos ASV support is added.
Also while at it fix the number of cooling down steps for big cores
(should be 11 instead of 12 on Odroid XU3 Lite and 14 on XU3/XU4).

[mszyprow: rebased onto v5.5-rc1 and adapted to recent dts changes,
fixed removal of the 1.4GHz OPP for A7s on Peach-Pi]

Declare Exynos5422/5800 voltage ranges for OPPs for big CPUs
(Cortex-A15) and wcore bus. Couple their voltage supplies as vdd_arm
and vdd_int should be in 300 mV range.

In order to get the clock by phandle and use it with regmap it needs to be
compatible with syscon. The DMC driver uses two registers from clock
register set and needs the regmap of them.

CAM power domain contains CAMIF, 3AA and FIMC LITE devices. It is present
only in Exynos 5422/5800 SoCs. Currently there are no drivers nor the
device nodes for those devices, but instantiating its power domain allows
to turn it off and save some energy.

Compiling the DT file with W=1, DTC warns like follows:
Warning (unit_address_vs_reg): Node /opp_table0/opp@1000000000 has a
unit name, but no reg property
Fix this by replacing '@' with '-' as the OPP nodes will never have a
"reg" property.

Fix CPU operating points for Exynos5800 (it use different
voltages than Exynos5420 and supports additional frequencies).
However don't use 2000MHz & 1900MHz OPPs (for A15 cores) and
1400MHz OPP (for A7 cores) for now as they are not available
on all boards.
Based on Hardkernel's kernel for ODROID-XU3 board.

Most of the nodes of exynos5420 remains same for exynos5800.
So the exynos5420.dtsi is included in exynos5800 and the changed
node properties will be overriden.
