[PATCH v3 00/12] arm64: dts: rockchip: Add NanoPi M6 board

[Joachim Eastwood via B4 Relay]

This patch series add support for the NanoPi M6. This board is very
similar to the NanoPi R6C and R6S boards which are already supported.

Main differences:
* M.2 M-key slot with PCIe (Also present on R6C)
* M.2 E-key slot with PCIe and USB (from hub)
* 1 additional USB 2.0 port from an on-board USB hub
* RT5616 audio CODEC

Patch 1 documents the NanoPi M6 board compatibility string
Patch 2 to 10 are fixes and additions to the nanopi-r6 base DT
Patch 11 extracts the common NanoPi 6 series bits from nanopi-r6 into
nanopi.dtsi
The final patch adds support for NanoPi M6. Support for M6 has been
split into two files; one dtsi and one dts file. This makes it easier
to add support to the new M6V2 board at a later stage.

All changes have been verified using the schematics for M6, R6C and R6S.
Only M6 have been boot and runtime tested. Testers for R6x are welcome.

Changes in v3:
- Reorder patches so the DT fixes/additions are applied to
  nanopi-r6.dtsi as suggested by Jonas Karlman
- Add comment to gmac to rgmii-rxid phy-mode to explain usage
- Addition of pinctrl to sd and pcie are now marked as fixes
- Remove both always-on and boot-on from NPU regulator
- Link to v2: https://patch.msgid.link/20260711-nanopi-m6-v2-0-422675a65402@gmail.com

Changes in v2:
- Organize DT such that adding support to NanoPi M6V2 later is easier
- Use correct clk id for I2C mclk out as suggested by Diederik.
- Add a couple of acks from Krzysztof Kozlowski.
- Link to v1: https://patch.msgid.link/20260703-nanopi-m6-v1-0-8344a1559519@gmail.com
