According to my copy of the documentation (v2.00) SDH, SD0 and SD1 do
not seem to be provided by the r8a7792 CPG.

It does, however, provide RCAN and ADSP which are supported by the CPG
driver. You may wish to add them now for completeness though from my point
of view they could also be added later when they are used.


I reviewed the values below. They appear to be complete and correct.
