I don't know what does it mean. This is v1, so we don't expect
changelog. If this is v2 (because there was RFC/RFT/RFkisses/RFhugs
which are states of patchsets, not versions), then please mark it as v2
and put changelog under ---.

Drop "Bindings for" and instead describe the hardware. You are
duplicating now title.

This won't match to anything... missing compatible. You probably want to
align with ongoing work on the lists.

Only one blank line.

You have broken indentation.

Use 4 spaces for example indentation.
