V2:
 - Add R-b/A-b tag
 - Merge V1 patch 13 to V2 patch 6
 - Drop V1 patch 15
 - Merge V1 patch 16 to V2 patch 5 and add comments in patch 5 to explain
 details
 - Add explaination in patch 8 for "why the resets are not defined"

This patchset is a pick up Lucas's gpcv2 work for i.MX8MM and several
minor changes from me to make it could work with i.MX BLK-CTL driver.

Thanks for Lucas's work and suggestion, Frieder Schrempf for collecting
all the patches, Jacky Bai on help debug issues.

It's nice to see this finally moving forward!

As you know, Hantro G2 support for i.MX8MQ (and i.MX8MP, i.MX8MM) is currently
blocked, as you have requested:

https://lore.kernel.org/driverdev-devel/5aa5700b862234895a7a6eb251ca3c80fdc1a6d3.camel@collabora.com/ (local)

So, I think we really need to include i.MX8MP and i.MX8MQ on this series.
It's been quite a while and we really need to have that. To be honest,
I fear that
if we merge this series as-is, MX8MP and MX8MP support will fall in
the oblivion,
and Hantro G2 VPU will remain unusable.

We are planning to submit Hantro G2 VP9 support soon, and we've been testing
on various platforms, but it will also be blocked by lack of power-domains.

In the future, please Cc the linux-media mailing list, as well as
Benjamin, Andrzej and myself, so we can follow this.

Thanks a lot for the hard work!
