Applied, thanks!
[1/3] dt-bindings: Add doc for Fastrhino R66S / R68S
commit: b985ca5261171e559f4d9754481b5f6c6e15ad93
[2/3] arm64: dts: rockchip: Add Lunzn Fastrhino R66S
commit: ddb6cde1cf59eb57820a6c277b8b5cff45e68d68
[3/3] arm64: dts: rockchip: Add Lunzn Fastrhino R68S
commit: 5a9447fd17668c34449052e4f77eebc7a98eccf3
[v6.5-armsoc/dts64 branch, will be rebased once more after 6.4-rc1,
resorted some properties to be more alphabetically sorted
dropped one empty line at the end of the pmic node]
