No problem. I thought the focus would be on the 8MP,m so I went ahead
and posted a series [1] for enabling the gpcv2 for the Nano and the
power domains which don't require blk-ctl for now which include the
USB OTG, and the GPU.

If you and/or your colleagues have time to review it, it would be
appreciated. I was able to suspend and resume with USB attached, and
it continued to operate. I didn't do extensive testing yet.
I'm starting on the blk-ctl stuff now. It seems to have changed quite
a bit since the initial submission from Abel, so I'll have to spend a
bit more time porting what I had before.

Thanks again for this series. It will be nice to have the Mini, Nano
and Plus domains functional.
