[PATCH v2 0/9] arm64: dts: rockchip: NanoPi 6 series fixes and improvements

[Joachim Eastwood via B4 Relay]

This patch series contains a few fixes and miscellaneous improvements
for the NanoPi 6 series of boards.

Patch 1 fixes the voltage range on the SDMMC regulator.
Patch 2 enables HS400 mode on eMMC. Tested on my M6 board.
Patch 3 adds an IIO HWMON device to monitor the input voltage.
Patch 4 moves a regulator that only exist R6 boards to the correct dtsi.
Patch 5-9 renames DT names to match the schematics signals/nets.

If patch 5-9 is just considered churn I'll drop them. These are more
nice to have and just makes it easier to cross-reference DT and
schematics.

Schematics for the boards can be found here:
