[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:
M6: https://wiki.friendlyelec.com/wiki/images/8/85/NanoPi_M6_2405_SCH.PDF
R6C: https://wiki.friendlyelec.com/wiki/images/f/f7/NanoPi_R6C_2302_SCH.PDF

[PATCH v2 1/9] arm64: dts: rockchip: rk3588s-nanopi: fix sd min/max voltage

[Joachim Eastwood via B4 Relay]

From: Joachim Eastwood <joachim.eastwood@gmail.com>

This regulator is only a simple power switch and cannot change the
output voltage.

[Joachim Eastwood via B4 Relay]

From: Joachim Eastwood <joachim.eastwood@gmail.com>

The NanoPi 6 series all support eMMC 5.1 HS400 mode. This also matches
the vendor device tree. Also add power supplies while at it.

[PATCH v2 3/9] arm64: dts: rockchip: rk3588s-nanopi: add voltage iio-hwmon device

[Joachim Eastwood via B4 Relay]

From: Joachim Eastwood <joachim.eastwood@gmail.com>

The NanoPi 6 series have a resistor divider on the main input supply to
support voltage measurements. Hook this up as a hwmon device so it is
possible to monitor the voltage.

Output from sensors on NanoPi-M6:
vdd_usbc_iio_hwmon-isa-0000
Adapter: ISA adapter
in1:     19.80 V

[PATCH v2 4/9] arm64: dts: rockchip: rk3588s-nanopi: move vcc_3v3_s0 to nanopi-r6

[Joachim Eastwood via B4 Relay]

From: Joachim Eastwood <joachim.eastwood@gmail.com>

This regulator (power switch) is only present on R6 boards, and not M6
boards. It is regulator-always-on and regulator-boot-on because it's
controlled by the vcc_1v8_s0 power rail from the PMIC.

On R6 boards it's used by the Ethernet phy, and some VCCIO rails on the
SoC itself.

looks like we worked at the same time :-) .

As you will have seen just now, I applied your v1, so please send any
needed changes as follow up patches.


Thanks
