[v3,00/24] sunxi: Allwinner T113s support

Hi,

this is just for the records (mailing list archives), I just sent a
pull request with that series, to still make the 2024.01 merge window.
Some smaller changes, addressing the review comments (many thanks to
Samuel!) This now embeds Sam's PSCI support patches, and also relies
on the devicetree sync from the Linux v6.6-rc6 kernel.

If you find issues with this series, then please reply to the respective
patch, or send a patch on top. We still have till the end of the year to
fix things in the repo.
Changelog below.

===================
This series adds support for the new SoC series that covers the Allwinner
D1 siblings R528 and T113s (a version with co-packaged DRAM). They all
share the same die, although the D1 and D1s use RISC-V cores, which
requires more plumbing, to use the sunxi code across two architectures.
Getting the R528 support in should help a bit in sorting out what's new
peripheral code and what is architecture dependent. IIUC, Samuel has that
running, although with some hacks, the number of which this series tries
to reduce.

The most interesting part of this is the pincontroller rework, this
tackles two issues:
- For the first time in the history of mainline Allwinner support the
  pincontroller changed the register layout. The code here tries to
  abstract the differences away, so both variants can share the code
  peacefully.
- For the above mentioned reason, the pincontroller code is quite old,
  and is mostly spread out across arch/arm, in a pre-DM style, even
  though we have real DM support in U-Boot proper. We need the non-DM
  version for the (ARM-only?) legacy SPL, so can't get rid of that
  completely. This series also tries to modernise that code, and moves
  it into drivers/gpio, where it can be more easily shared with RISC-V.

The main feature is then of course the T113s support, of which the new
pinctroller is only one part. Apart from the new pincontroller and the
usual new SoC bits (like clock and pinmux support), this includes the
DRAM controller code.
The PSCI support has been contributed by Sam (many thanks for that!).
To follow the common pattern there is first some refactoring, then the
R528/T113s bits plug on top.
With the basics in, we add support for the MangoPi MQ-R board, which
uses the T113s and seems to be a popular board. This should also serve
as a blueprint for supporting similar boards.

This series is based on top of current master, but it relies on the
Allwinner DT update series (from Linux kernel v6.6-rc6).

A branch is available at:

Cheers,
Andre
