Hi all,

second revision of the GPC improvements and BLK_CTRL driver to make use
of all the power-domains on the i.MX8MM. I'm not going to repeat the full
blurb from the v1 cover letter here, but if you are not familiar with
i.MX8MM power domains, it may be worth a read.

This 2nd revision fixes the DT bindings to be valid yaml, some small
failure path issues and most importantly the interaction with system
suspend/resume. With the previous version some of the power domains
would not come up correctly after a suspend/resume cycle.

Updated testing git trees here, disclaimer still applies:

I finally did some tests on my side using USB, GPU and DSI (no PCIe, VPU, CSI so far) and the results are promising. Thanks for the effort!

I will try to run some more automated suspend/resume and reboot test cycles over the weekend and report the results here afterwards.
