Antoine,

nit: there is no gated clock for the ADC, I guess we can just always
enable it. That will save you the last patch of the series.

BTW, I have the strong feeling that moving berlin's clk drivers to
regmap will block any subsequent patches you are preparing. How about
we target the next merge window for moving the clk node but not the
drivers (except of_iomap of the _parent's_ reg property) and push the
less controversal patches (pinctrl, reset) with regmap/syscon forward?
