One last question: is this the location given as .grf_offset the
only thing in grf that is potentially of concern to this driver?
If it is, you can change the binding to include the register number
in the syscon reference, like
rockchip,grf = <&grf 0x154>;
and then read it from there, to simplify the code needed to get the
number from the device id.
