Subject: [PATCH v2 0/4] ARM: dts: sunxi: Add MangoPi MQ-R board support

Hi,

this is v2, mostly acknowledging the fact that there is an Allwinner D1s
version of the board as well, thus splitting the board .dts into a
shared .dtsi and a stub .dts for the ARM version. I don't have the RISC-V
version, so cannot provide (nor test) this .dts file, but creation should
be easy, being based on the shared board .dtsi file.
Since the D1/D1s .dts files are now merged, this patch set should compile
cleanly now.

======================================

The MangoPi MQ-R-T113 is a small SBC with the Allwinner T113-s3 SoC.
That is a very close relative to the Allwinner D1/D1s SoCs, but with
Arm Cortex-A7 cores, and 128 MB of SIP co-packaged DDR3 DRAM.

This series introduces the missing T113-s .dtsi, which builds on top of
the D1/D1s .dtsi, but adds the ARM specific peripherals, like the CPU
cores, the arch timer, the GIC and the PMU.
This requires to add a symlink to the RISC-V DT directory in patch 1/4,
to be able to easily reference the base .dtsi from other architecture
directories.
Since there are versions of the MQ-R boards with the Allwinner D1s,
there is shared .dtsi describing the board peripherals, plus a small
stub .dts to tie together all bits for the actual board.

Cheers,
Andre

Changelog v1 ... v2:
- rebase on top of v6.3-rc3 (including now merged D1/D1s .dtsi files)
- refine board naming, stating both RISC-V and ARM versions
- move board .dts into a shared .dtsi (to cover RISC-V version)
- fix 5V regulator node name
