Hey Krzysztof,
Thanks for taking time to review the series :)

What other Hamoa boards are you referring to? The series
mentions that the driver and bindings is meant for Qualcomm
Hamoa/Purwa/Glymur "reference" devices, so it only covers
CRD and IOT-EVK. It definitely does not cover all Hamoa boards
boards like you are assuming.
