Which is why we may start thinking of common and generic "regmap" compatible
solution in the CCF, at least for things like gates, dividers and muxes

The approach used in qcom with regmap clocks could be a candidate for this,
don't you think ?

Syscon has been created exactly for this case where you want to create an mfd
just for sharing a register region between several, otherwise well separated,
devices, isn't it ?
