setting the performance state of Venus.

Humm, looks suspicious. This is a phyical power island in this block?
Because that's what 'power-domains' are supposed to represent. Not $os
pm-domain construct.

yes, this is used to represent the physical 'cx' power island in the SoC
(Its a shared power island, not a power island specific to this block)
that can be scaled to different 'performance levels' based on the frequency
the codec is expected to run at.

Rob, Did you have any other concerns here? Should I be re-posting this?
