Re: [PATCH] ARM: dts: r7s72100: fix sdhi clock define

I have no idea if the SDHI driver disables the module clock when it is
idle, but shouldn't the card detect clock be running all the time when the
driver is bound to the device?

Yes, it should. And for all instances with just one clock, this means
this main clock must be running. So, en-/disable functions are all about
suspend/resume and bind/unbind. (Huh, looks like the unbind part is
missing, though. Need to look closer).

My take is: either we implement the power saving and handle the cd clock
seperately. Or we ignore the power saving for now and handle both clocks
as virtually one, i.e. en-/disable them at the same time.

Doesn't make sense?
