This is rather overkill since currently all drivers call this from
hardirq (or at least timers). But maybe in the future we're going to
have thread irq handlers and what not, doesn't hurt to be prepared.
Plus this is an easy start for sprinkling these fence annotations into
shared code.
Cc: linux-
This is a bit disappointing since we need to split the annotations
over all the different parts.
I was considering just leaking the critical section into the
->atomic_commit_tail callback of each driver. But that would mean we

This is needed to signal the fences from page flips, annotate it
accordingly. We need to annotate entire timer callback since if we get
stuck anywhere in there, then the timer stops, and hence fences stop.
Just annotating the top part that does the vblank handling isn't
enough.

At some point PWM cell count was changed, but it didn't triggered any

To make sure, we are in sync with the kernel driver, remove this
property and fix the pwm consumer.

Since the encoders have been devm-allocated, they will be freed way
before drm_mode_config_cleanup() is called. To avoid use-after-free
conditions, we then must ensure that drm_encoder_cleanup() is called
before the encoders are freed.

The meta-schema recently gained a definition for the common -supply$
property, which denotes that maxItems is not a valid property. Drop this

This is the v6 series to introduce i.MX8qm/qxp Display Processing Unit(DPU)
DRM support.
DPU is comprised of a blit engine for 2D graphics, a display controller
and a command sequencer. Outside of DPU, optional prefetch engines can
fetch data from memory prior to some DPU fetchunits of blit
