Co-developed-by: Mansur Alisha Shaik <mansur@codeaurora.org>
Signed-off-by: Dikshita Agarwal <dikshita@codeaurora.org>

change since v3:
 - added firmware node back.
change since v2:
 - removed firmware node.
change since v1:
 - added rpmh power domain and opp table.

this patch depends on [1],[2] & [3].

Please remove the leading 0 after the "@" sign

Unless there was a newer revision of [1], the cx pd will most likely

be unused due to it not being specified under opp_pmdomain.

Is there a downstream kernel source available for sc7280 to compare against?

I don't see it in sm8350 releases and it's hard to tell out of thin air what values

should be in there.. Unless qcom decides to share some documentation ;)


Besides that, I don't see the driver part being merged neither in linux-next, nor media-next but I may be looking at the wrong tree.

Is this going to be resent?
