[PATCH v1 0/2] Add FriendlyElec NanoPi M5 support for Rockchip RK3576

[PATCH v1 0/2] Add FriendlyElec NanoPi M5 support for Rockchip RK3576

[John Clark]

This series adds device tree support for the FriendlyElec NanoPi M5 board,
powered by the Rockchip RK3576 SoC (4x Cortex-A72, 4x Cortex-A53, Mali-G52
MC3 GPU, 6 TOPS NPU). The patches enable basic booting and connectivity,
including dual 1Gbps Ethernet, USB 3.2, microSD, M.2 PCIe NVMe, and HDMI.

Patch 1 updates the DT bindings in rockchip.yaml.
Patch 2 adds the NanoPi M5 device tree and Makefile entry.

No MAINTAINERS update is needed, as the new file is covered by the existing
ARM/Rockchip SoC entry.

Tested on NanoPi M5 with successful boot and feature validation.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: tags/v6.16-rc1-19-gd7ad90d22abe (exact match)

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)

apart from the schema problems, Rob's bot found, I saw some additional
nitpicks below.

nodes without addresses should get sorted by nodename
aka regulator-* before sound.

Phandles count into the sorting only below in the
&phandle {}; parts

blank lines between properties and subnodes please.
same for other regulators below and also the pmic.

comment could state a tiny bit more what is changed compared to
