Filename based on family of devices or compatible (assuming it is
correct): nxp,w8987-bt.yaml

Hyphen is not a correct separator between vendor prefix and device name.

This is description of binding. So in description of binding for NXP
bluetooth chips you say that it describes NXP bluetooth chips. I don't
think it's useful. Describe the hardware instead.

Why "bt" suffix? Are these chips coming with other functions?

default?


No interrupts or power supplies on these chips?
