Could you update the commit description to match device tree. It looks
like the M.2 2242 socket is configured as a SATA (i.e. "sata2")
instead of NVME.

Is the M.2 slot also wired for NVME operation? If so, will you be
providing a DT overlay to use it in that mode?

Does the board support hdmi0_sound and hdmi1_sound (and the
corresponding i2s5_8ch and i2s6_8ch)?

These properties should be in alphabetical order.
