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.

Recent changes to the thermal framework has made the trip
points (trips) for thermal zones compulsory, which made
the Ux500 DTS files break validation and also stopped
probing because of similar changes to the code.
Fix this by adding an "outer bounding box": battery thermal
zones should not get warmer than 70 degress, then we will
shut down.

This force-converts the per-device battery node into the standard
properties using "simple-battery" for the HREF machines and the
corresponding Samsung battery for the mobile phones.
This is fine to do since the battery data in the DTS files has never
been deployed or used. In commit a1149ae97554
"ARM: ux500: Disable Power Supply and Battery Management by default"
it was turned off and has not been switched back on since. In
the meantime standardized bindings for batteries have appeared
making the old AB8500 battery bindings obsolete.
The battery node which is now in the middle of an included file
is obviously a per-device piece of information so push this down
to each board. The HREF machines all have the same battery and can
share a single node in the HREF dtsi file.

The Ux500 HREF LEDs have not been probing properly for a
while as this was introduce:
ret = of_property_read_u32(np, "color", &led_color);
if (ret)
return ret;
Since the device tree did not define the new invented color
attribute, probe was failing.
Define color attributes for the LEDs so they work again.

for some machines. To clearly distinguish between the

At the moment, all 5 I2C and 6 SPI buses are probed and exposed
to user-space by default - even if they are not muxed to any pins
on the board. This means that user-space sees an I2C/SPI bus that
cannot be actually used properly.
In some cases this was used to put the corresponding pins into
a low power sleep mode - but even then the pins first need to be
configured by the board-specific device tree part.
Avoid exposing unconfigured devices to user-space by disabling
the I2C/SPI buses by default. Enable them in the board device trees
when needed.

Some components (e.g. SDI, I2C) can be used with different pin assignments.
Before we can add the alternative configurations, we need to rename the
current configurations to more generic names.
Each pin configuration usually configures one specific pin group.
Therefore we rename the configurations to use the pin group as name.
Make up for the slightly longer names by removing the "_mode" suffix.
Rename all existing uses to use the new labels.

Ux500 is regressing due to commit
a21763a0b1e5a5ab8310f581886d04beadc16616
"pinctrl: nomadik: activate strict mux mode" which disallows
Nomadik GPIO 5 to be muxed in as a level shifter voltage select
pin, as it is currently described as being used for RX on UART1.
The behaviour is correct, instead the hardware config has been
incorrecly specified: UART1 is indeed unused on HREFv60plus and
Snowball and that is why HREFv60plus can use the pins it would
normally occupy as the voltage select line for the MMC/SD
levelshifter (Snowball uses it for I2C4).
The reason UART1 was anyway enabled on these platforms was
probably to secure the port enumeration to userspace. This
can be solved by using aliases (done in a separate patch) so
we can now deactivate UART1 and let MMC/SD use it properly
on HREFv60plus. We explicitly activate it only for the
older HREFprev60 board.
To complete, we set up the pin configuration for these pins
properly in the sdi0 node.

The Ux500 boards are layered like this:
ste-snowball.dts includes ste-href.dtsi that includes
ste-dbx500.dtsi.
The dbx500.dtsi defines the PRCMU SoC regulators so the SoC will
probe and you can use ampersand references where need be.
However the HREF common dtsi and these two boards redefine the
same PRCMU SoC regulators with the very same names and properties
for no reason. This is like filling in the same line three
times instead of drawing it once. Just delete the surplus
references and have the PRCMU regulators defines in the SoC
