The Orange Pi CM5 Base board is a carrier board for the Orange Pi CM5 compute module. It has 3 ethernet ports, 2 USB ports, one HDMI output and 4 CSI-2 inputs.
The device tree is split in two files, a .dtsi for the compute module and a .dts for the carrier board. All the devices present on the carrier board are enabled and tested, with the exception of the IR receiver due to missing support for input capture in the PWM device's DT binding (and driver). This work is based on a combination of the Orange Pi 5 device tree from the upstream kernel and the Orange Pi CM5 device tree from the BSP kernel. All nodes and properties have been carefully checked to the best of my abilities against the schematics of the carrier board. The schematics of the compute module is not available publicly, so the configuration of the PMIC hasn't been double-checked.
