The arm dts directory has grown to 1559 boards which makes it a bit
unwieldy to maintain and use. Past attempts stalled out due to plans to
move .dts files out of the kernel tree. Doing that is no longer planned
(any time soon at least), so let's go ahead and group .dts files by
vendors. This move aligns arm with arm64 .dts file structure.
There's no change to dtbs_install as the flat structure is maintained on
install.
The naming of vendor directories is roughly in this order of preference:
- Matching original and current SoC vendor prefix/name (e.g. ti, qcom)
- Current vendor prefix/name if still actively sold (SoCs which have
been aquired) (e.g. nxp/imx)
- Existing platform name for older platforms not sold/maintained by any
company (e.g. gemini, nspire)
The whole move was scripted with the exception of MAINTAINERS and a few
makefile fixups.

Previously, the mshc0 alias has been necessary so that
MMC_CAP_1_8V_DDR | MMC_CAP_8_BIT_DATA are set for mshc_0/mmc_0.
However, these capabilities should be described in the device tree so
that we do not have to rely on the alias.
The property mmc-ddr-1_8v replaces MMC_CAP_1_8V_DDR, while bus_width =
<8>, which is already set for all the mshc0/mmc0 nodes, replaces
MMC_CAP_8_BIT_DATA.
Also drop other mshc aliases as they are not needed.

Commits 1019fe2c7280 ("ARM: dts: exynos: Adjust bus related OPPs to the
values correct for Exynos5422 Odroids") and 9ff416cf45a0 ("ARM: dts:
exynos: Disable frequency scaling for FSYS bus on Odroid XU3 family")
revealed that 'opp-shared' property for the Exynos bus OPPs was used
incorrectly, what had the side-effect of disabling frequency scaling for
the second and latter buses sharing given OPP-table.
Fix this by removing bogus 'opp-shared' properties from Exynos4412 bus
OPP-tables. This restores frequency scaling for the following buses:
C2C, RightBus, and MFC.

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:

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.

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

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

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.

Add CPU operating points for Exynos4412 Prime (it supports
additional 1704MHz & 1600MHz OPPs and 1500MHz OPP is just
a regular non-turbo OPP on this SoC). Also update relevant
cooling maps to account for new OPPs.
ODROID-X2/U2/U3 boards use Exynos4412 Prime SoC version so
update their board files accordingly.
Based on Hardkernel's kernel for ODROID-X2/U2/U3 boards.

Mark 800MHz OPP as a suspend opp for Exynos4412 based
boards so effectively cpufreq-dt driver behavior w.r.t.
suspend frequency matches what the old exynos-cpufreq
driver has been doing.
This patch fixes suspend/resume support on Exynos4412 based
Trats2 board and reboot hang on Exynos4412 based Odroid U3
board.

For Exynos4x12 platforms, add CPU operating points (using
opp-v2 bindings) and CPU regulator supply properties for
migrating from Exynos specific cpufreq driver to using
generic cpufreq driver.
Based on the earlier work by Thomas Abraham.
