The "compatible" property text contradicts even the example given in the MMCIF binding document itself; moreover, the Renesas MMCIF driver only matches on the generic "compatible" string and doesn't look for the SoC specific strings at all. Thus describe "renesas,sh-mmcif" as a fallback value.

I don't believe this file is the appropriate place to describe best-practice for the ordering of compatible strings which must surely be documented elsewhere.
Where? I have no idea what you mean... And let me reiterate: this text is *wrong* and needs to be fixed anyway.

Changes in version 2: - kept the SoC specific "compatible" property values mandatory and made the generic string a fallback.
