You are trying to regroup several controllers into one with this, and it is not OK By the looks of it there are 3 different controllers, including one you did not implement in the driver. Yes, In A1, the clock registers include three regions. I agree with your opinion. I will implement the two clock drivers of peripheral and plls first in PATCH V2. And CPU clock driver will be sent after the patches are merged. +clocks = < +clock-names = "xtal"; +#clock-cells = <1>; .
