As pointed out by "arm64: dts: qcom: hamoa-iot-evk: Enable display
support" this is incomplete. Adding new SoM or board is one commit. Not
two. Don't split board DTS, which is already prepared/ready, into
multiple fake commits. This is not a release early approach. This is
opposite!

Best regards,
Krzysztof
