Add support for PIL loading of WPSS co-processor for SC7280 SOCs.
Changes from v3:
- Add separate dt-bindings file for sc7280-wpss-pil
- Fix the handling of single power domains for adsp/cdsp from v3

Add support for PIL loading of WPSS processor for SC7280
- WPSS boot will be requested by the wifi driver and hence
disable auto-boot for WPSS.
- Add a separate shutdown sequence handler for WPSS.
- Add multiple power-domain voting support

Maybe spell out WPSS so we know what the acronym means?

Are there any required properties of glink-edge? Or an empty node is all
that's required? Maybe there's a binding that can be referenced here
that describes the required properties?

Can we remove status = "disabled" from the example? It provides no
value.

What happened to converting the existing binding? Given you already
did that, please don't drop it.

Don't need minItems unless it is less than 'items' length.

ahb_bdg, ahb, rscp is sufficient. Or use the same names as prior
versions (did the h/w clocks change?).

string or string-array?

This says only 1 entry, so 'string'.

Hi Rob,
Thanks for the review.
Sure, let me post v5 with other comments on this patch-series addressed.
I will also include the yaml conversion for existing dt-bindings.
Thanks,
