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.

According to gpio-hog schema, should add the suffix "-hog" to the node
names including gpio-hog to fix the following warning.
uniphier-pro4-ref.dtb: gpio@55000000: 'xirq2' does not match any of the regexes: '^.+-hog(-[0-9+)?$', 'pinctrl-[0-9]+'
From schema: Documentation/devicetree/bindings/gpio/socionext,uniphier-gpio.yaml
This applies to the devicetree for LD4, LD6b, Pro4 and sLD8 SoCs.

Since commit e69f5dc623f9 ("dt-bindings: serial: Convert 8250 to
json-schema"), the schema for "ns16550a" is checked.
Since then, 'make ARCH=arm dtbs_check' is so noisy because the
required property 'interrupts' is missing.

Add an 'aliases' property for ethernet device.
U-Boot performs a fix-up of the MAC address and will overwrite the values
from the Linux devicetree for aliased ethernet device. The MAC address can
be inherited from U-Boot by adding aliases of ethernet devices.

With commit d8e8fd0ebf8b ("mtd: rawnand: denali: decouple controller
and NAND chips"), the Denali NAND controller driver migrated to the
new controller/chip representation.
Update DT for it.
In the new binding, the number of connected chips are described in
DT instead of run-time probed.
I added just one chip to the reference boards, where we do not know
if the on-board NAND device is a single chip or multiple chips.
If we added too many chips into DT, it would end up with the timeout
error in nand_scan_ident().
I changed all the pinctrl properties to use the single CS.

According to Documentation/process/license-rules.rst, move the SPDX
License Identifier to the very top of the file. I used C++ comment
style not only for the SPDX line but for the entire block because
this seems Linus' preference [1]. I also dropped the parentheses to
follow the examples in that document.

Add NAND controller node to LD4, Pro4, sLD8, Pro5, and PXs2.

I did not enable it.

Follow the recent trend for the license description, and fix the wrongly
stated X11 to MIT.
The X11 license text [1] is explicitly for the X Consortium and has a
couple of extra clauses. The MIT license text [2] is actually what the
current DT files claim.

These UniPhier DT files are fine as long as they are compiled in the
Linux build system. It is true that Linux is the biggest user of
DT, but DT is project neutral from its concept. DT files are often
re-used for other projects. Especially for the UniPhier platform,
these DT files are re-used for U-Boot as well.
If I feed these DT files to the FDTGREP tool in U-Boot, it complains
about the node order.
FDTGREP spl/u-boot-spl.dtb
Error at 'fdt_find_regions': FDT_ERR_BADLAYOUT
/aliases node must come before all other nodes
Given that DT is not very sensitive to the order of nodes, this is a
problem of FDTGREP. I filed a bug report a year ago, but it has not
been fixed yet.
Differentiating DT is painful. So, I am up-streaming the requirement
from the down-stream project.
