According to my copy of the documentation (v2.00) SDH, SD0 and SD1 do
not seem to be provided by the r8a7792 CPG.
I've just downloaded and opened rev2.00 manual, and still, there's no
CPG registers other than FRQCRB on V2H.
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.
My copy of the manual says there's no ADSP on V2H, and thus no ADSP clock.
I was looking at Figure 7.1c. Perhaps it is inaccurate.
Indeed, it's the only place where the ADSP clock is mentioned for V2H, and
it looks like this is in error. I guess I'll try to verify if there's writable
ADSPCKCR and then remove the ADSP clock if not.
MBR, Sergei
