Subject: [PATCH 00/10] media: hantro: imx8mq/imx8mm: Let VPU decoders get controlled by vpu-blk-ctrl

Both the i.MX8MQ and i.MX8MM have G1 and G2 decoders.
The two decoders are similar, but the imx8mm lacks the
post-processor, so they will have distinct compatible flags.
Splitting the i.MX8MQ VPU into G1 and G2 makes it easier to
control them independently since the TRM of both the i.MX8MQ and
i.MX8MM list them as distinct IP blocks.  With them being split,
the power-domain can shift to the vpu-blk-ctrl which is available
on both i.MX8MQ and i.MX8MM but some of bits are different, so
they'll have separate device tree bindings.
Lastly, with the G1 and G2 operational, enable the i.MX8MM.
On the i.MX8MM, the clock speed of 600MHz was chosen to match
the default of the kernel repo from NXP and can be overwritten
by board files for anyone who under/over volts the power rail.

The repo used as the starting point was:
   git://linuxtv.org/hverkuil/media_tree.git for-v5.17e

This media hantro group has been especially helpful in helping
me get up to speed on how it works.

Fluster was run on the i.MX8M Mini at 600 MHz:

./fluster.py run -d GStreamer-VP8-V4L2SL-Gst1.0
Ran 55/61 tests successfully               in 8.299 secs

./fluster.py run -dGStreamer-H.264-V4L2SL-Gst1.0
Ran 90/135 tests successfully               in 71.200 secs

./fluster.py run -d GStreamer-VP9-V4L2SL-Gst1.0
Ran 139/303 tests successfully               in 218.079 secs
