pinctrl is already in Linus Walleijs tree :-)

Tomorrow I'll try to send the mmc stuff to the mmc lists, as my dw-mmc 
dependency from Dinh Nguyen also seems to go this way.

The clocks are the really hard part, simply because Mike's upcoming dt support 
for the divider and mux clocks will let me get rid of the small clocks that 
simply hold. And of course I also need the HIWORD_MASK flag for the clocks from 
the hisilicon series.

Is there some sane intermediate step for the clocks? One possibility that 
comes to mind, would be to only declare the gates and provide fixed rate 
parents to the timer and mmc and add the divs and muxes when Mikes dt patches 
are ready.

I.e. I would keep the gate clocks grouped like now to not have to declare 160 
individual gates later :-)
