Should it be called "boot state" then? That idea sounds OK to me.

Stray 's' here.

Care to explain more? Presumably you mean when firmware is modifying clk
state without notifying the kernel? In which case it should be called
"hardware enable" or something like that and be a "Y/N/?" value
depending on if the value can be read or not and if it is enabled or not?
