No worries! The code above is at least consistent and matches the common current case. >> No need to rework existing stuff IMO.

From my point of view that seems like an opportunity worth taking. So shall we leave the SYS-DMAC as-is or change things around? I personally don't see the point in redoing things just to change order, so keep as-is sounds good to me. For the "fallback" CMT DT compat strings I think we should follow the proposal from Geert and go with "renesas,rcar-gen2-cmt0". Regarding the per-soc CMT DT compat strings my feeling is that we should follow the same order as SYS-DMAC to keep things consistent.
