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

The MangoPi MQ-R 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.

After I had written most of the board .dts, I realised that the
MangoPi MQ is almost the same, minus the RISC-V/ARM difference. I am a
bit unsure if we should share more of the board .dts, though, as this
would go cross architectures. I am open to any comments here.

Please have a look!

Cheers,
Andre
