Subject: [RFC PATCH 0/4] split rk3568 and rk3566 device trees

This is an example patch set that addresses the split of the rk3568 and
rk3566 soc device trees.
This method attempts to avoid deleting and modifing nodes by maintaining
a common dtsi for all common items and adding in the differences in
separate dtsi files.
It also includes a basic dts for the Pine64 Quartz64 Model A board
as an example of a rk3566 device.

This series has the following prerequisite:
arm64: dts: rockchip: add pmu and qos nodes for rk3568

Peter Geis (4):
  arm64: dts: rockchip: move rk3568 dtsi to rk356x dtsi
  arm64: dts: rockchip: split rk3568 device tree
  arm64: dts: rockchip: add rk3566 dtsi
  arm64: dts: rockchip: add basic dts for Pine64 Quartz64-A
