Merge tag 'drm-msm-next-2021-12-26' of ssh://gitlab.freedesktop.org/drm/msm into drm-next
* dpu plane state cleanup in prep for multirect
* dpu debugfs cleanup (and moving things to atomic_print_state) in prep
for multirect
* dp support for sc7280
* struct_mutex removal
* include more GMU state in gpu devcore dumps
* add support for a506
* remove old eDP sub-driver (never was used in any upstream supported
devices and modern things with eDP will use DP sub-driver instead)
* debugfs to disable hw gpu hang detect for (igt tests)
* debugfs for dumping display hw state
* and the usual assortment of cleanup and bug fixes
There still seems to be a timing issue with dpu, showing up on sc7180
devices, after the bridge probe-order change. Ie. things work great if
loglevel is high enough (or enough debug options are enabled, etc).
We'll continue to debug this in the new year.
