Subject[PATCH 0/7] arm64: dts: Initial RTD1395 and BPi-M4 support

This patch series adds initial Device Trees for Realtek RTD1395 SoC and
Banana Pi BPI-M4 SBC.

It is based on my RTD1195 series and James' pending RTD1619 DT bindings patch.

It starts with some refactorings to align the various SoCs and to demonstrate
to James what I meant with the r-bus node and GIC mask in RTD1619 DT v1 review.

RTD1395 family seems pretty similar to RTD1295 family, but allows for more RAM
and therefore uses #address-cells of 2 vs. 1, and it uses a different reserved
memory region for RPC. RTD1295 resets appear sufficiently compatible for now.

More details at:

Have a lot of fun!
