That looks alright.
prcm.h and prcm_sun6i.h are identical, apart from the header guards.
I could verify most of the sun50i PRCM fields by comparing to the Linux
CCU_R driver, but not all of them.
Out of curiosity, where do those offsets actually come from? Some BSP
code? And they are actually SUN50I_H6 aka. "NCAT" specific, right?
Anyway, the interesting part (R_I2C clock gate offset) is correct, so:
