Dragan Simic 296602b8e5 arm64: dts: rockchip: Move RK3399 OPPs to dtsi files for SoC variants
Rename the Rockchip RK3399 SoC dtsi files and, consequently, adjust their
contents and the contents of the affected board dts(i) files appropriately,
to "encapsulate" the different CPU and GPU OPPs for each of the supported
RK3399 SoC variants into the respective SoC variant dtsi files.

Moving the OPPs to the SoC variant dtsi files, instead of requiring the
board dts(i) files to include both the SoC variant dtsi file and the right
OPP variant dtsi file, reduces the possibility for mismatched inclusion and
improves the overall hierarchical representation of data.

These changes follow the approach used for the Rockchip RK3588 SoC variants,
which was introduced and described further in commit def88eb4d8 ("arm64:
dts: rockchip: Prepare RK3588 SoC dtsi files for per-variant OPPs").  Please
see that commit for a more detailed explanation.

No functional changes are introduced, which was validated by decompiling and
comparing all affected dtb files before and after these changes.  In more
detail, all decompiled dtb files remain exactly the same, except the files
list below, which results from all of them stemming from the same base board
dtsi file (rk3399-rock-pi-4.dtsi), while all of them include one of the three
different RK3399 SoC variant dtsi files by themselves:

  - rk3399-rock-4se.dtb
  - rk3399-rock-pi-4a.dtb
  - rk3399-rock-pi-4a-plus.dtb
  - rk3399-rock-pi-4b.dtb
  - rk3399-rock-pi-4b-plus.dtb
  - rk3399-rock-pi-4c.dtb

When compared with the decompiled original dtb files, these dtb files have
some of their blocks shuffled around a bit and some of their phandles have
different values, as a result of the changes to the order in which the
building blocks from the parent dtsi files are included into them, but they
still effectively remain the same as the originals.

The only exception to the "include only a SoC variant dtsi" is found in
rk3399-evb.dts, which includes rk3399-base.dtsi instead of rk3399.dtsi.
This is intentional, because this board dts file doesn't enable the TSADC,
so including rk3399.dtsi would enable the SoC to go into higher OPPs with
no thermal throttling in place.  Let's hope that people interested in this
board will fix this in the future.

As a side note, due to the nature of introduced changes, this commit is best
viewed using the --break-rewrites option for git-log(1).

Linux kernel
============

There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.

In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``.  The formatted documentation can also be read online at:

    https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
