Ok, I took another look just now (aa few minutes break)
One slight thorn is that the TMIO MFDs have a 1:1 card clock mode where the divisor is disabled. Annoyingly this is set up by a bit in the CNF IO space
How do non-TMIO (eg. superH) tmio cells select this mode? or do they simply not have a 1:1 ratio available to them?
(Im trying to decide whether to have a 'set 1:1' callback, or a 'set clock' callback. The latter is thorny because it'd involve the MFD core also mapping the CTL area.
