[PATCH v5 00/12] arm64: dts: rockchip: Add NanoPi M6 board

[Joachim Eastwood]

Hi Heiko,

I guess this missed the merge window for 7.3.
Do you want me to send a new version once 7.3-rc1 is out or will you
pick up this version?

There is one very simple conflict in
arch/arm64/boot/dts/rockchip/Makefile with the LubanCat4 support
commit.


best regards,
Joachim Eastwood
