Yes I agree, I will send some RFC patches which moves the reset controller
stuff into the generic code.
For v2 of this series I've removed the reset code, as stih416 doesn't have
seperate reset line each controller, so it will mainly be
useful for stih407 SoC, which needs additional patches on top of this
set.

Ok, removed in v2

Yes, I've updated to use readl_relaxed in v2

Removed in v2

Changed to dev_info in v2
