We already have issues with am62d that needs fixing:
cpu cpu0: _of_add_opp_table_v2: no supported OPPs
cpu cpu0: OPP table can't be empty
and
Please enable defconfig for this device
arch/arm64/boot/dts/ti/k3-am62d2-evm.dts: typec_pd0: usb-power-controller@3f {
We can look at adding features for am62d after the above are done.
