I agree with Viresh, this is patch 4 in a series where 1-2, 7- are new
things.

I can pick this from here, but I think it would have been better to send
this as 3-4 different series; 1 with DeviceTree fixes, 1 with driver
fixes, one that adds interconnect support and one that adds opp support
- the latter two with dts changes last...


And, the freq-table-hz -> opp transition in dts files must be merged
after the driver changes, so this will likely have to wait until 1
release after the driver changes.
