Just a nit again, but if struct definitions need to be wrapped, this looks
better:

{
	.io_start = 0...,
	.aclrcfg = ...,
	.num_actlrcfg = ARR..,
}, {
	.io_start = 0..,
	.aclrcfg = ...,
	.num_actlrcfg = ARR..,
};

Noted, will wrap this to keep each member in a new line as shown.
This looks much cleaner. Thanks for this suggestion.

so, PREFETCH_SWITCH_GFX seems to actually be two things, b5 is
actually PRR_ENABLE and b3 is ??

Probably you should drop the PRR_ENABLE, and perhaps give b3 a better name

BR,
-R

only b5 is not prr related bit as I checked now, will drop b3
and use this field for PRR bit only.
