I think the plan was to get rid of the renesas,cmt-48-* bindings, as they do
not allow to differentiate between CMT0 and CMT1, which have different feature
sets.

Cfr. Magnus' series "clocksource: sh_cmt: DT binding rework V4"
(https://lkml.org/lkml/2016/3/14/433).

Magnus: What's the status of your series?

Gr{oetje,eeting}s,
