Add code for common register bit definitions is OK, is it able to merge

into clock.h? Or maybe we can use cru.h and do some cleanup for clock.h

Can we just use cru.h as common header include by other cru_rkxx.h?

And then we can leave all the drivers including its cru_rkxx.h as-is.

The cru and grf regiesters are always different for different SoCs,

and only part of then have common  BIT definition.


Thanks,
