[RFC PATCH 1/1] arm64: dts: rockchip: add Radxa CM5 and IO board
Joseph Kogut

Wed May 14 10:38:56 PDT 2025
Add initial support for the Radxa CM5 and the accompanying IO board,
including ethernet, USB 2.0/3.0, PCIe 2.0, HDMI output, UART2 console,
SD/eMMC, PMIC.

This is my first attempt at submitting a new device tree upstream.
Feedback is welcome on DT conventions, naming, or anything I may have
missed.
This is largely reversed from the Radxa kernel sources as a reference.
