I'm thinking of using the same driver for both cases, and differentiate
between the two by compatible and `of_device_id.data`. Thus I propose to
have a "google,gs101-acpm-mbox" compatible for the ACPM SRAM case and in
the future we may add a "google,gs101-mbox" compatible for the messages
passed via the controller's data register case.

Good that you pointed it out, I was indeed wondering why this is
"acpm-mbox", not "mbox in compatible.

This needs to be fixed - you cannot have two compatibles for the same
device.

Will fix. I followed arm,mhu, which differentiates the transfer mode,
data or doorbell, via compatible.

There was a reasoning behind: different firmware.
