I need some guidance here, please. The mailbox controller can pass the
mailbox messages either via its own data registers, or via SRAM (like it
is used by the ACPM protocol).

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.

Given this, I shall use the more generic name for the bindings, thus
maybe "google,gs101-mbox.yaml"? But then exynos850 has the same
controller, shouldn't we just use "samsung,exynos.yaml"?

Thanks!
