Kaanapali SOC brings in the new generation of video IP i.e iris4. When
compared to previous generation, iris3x, it has,
- separate power domains for stream and pixel processing hardware blocks
(bse and vpp).
- additional power domain for apv codec.
- power domains for individual pipes (VPPx).
- different clocks and reset lines.
iommu-map include all the different stream-ids which can be possibly
generated by vpu4 hardware.
It's not how it can be defined.
Do you mean to elaborate the different entries within iommu-map or to elaborate the different stream ids and how they are grouped into different functions ?

This is totally underspecifified.
oneof would be a better approach describing the possible stream-ids.

#define the functions in the ABI, provide them in the bindings.
Ack. will introduce a new header at [1] and define these functions
