The drm_ati_pcigart_init() function was originally suppose to return one
on success and zero on failure, but these days it returns a mix of
zero, one and -ENOMEM on failure.
This patch cleans it up and modifies the caller so now the function
returns zero on success and negative error codes on failure.

To quote the E-DDC spec:
"... this standard requires that the segment pointer be
reset to 00h when a NO ACK or a STOP condition is received."
Since we're going to touch this might as well consult the

On the Amlogic GXL & GXM SoCs, a bug occurs on the primary plane when

The workaround Amlogic implemented is to reset the OSD1 plane hardware
block each time the plane is (re)enabled, solving the issue.
In the reset, we still need to save the content of 2 registers which
depends on the status of the plane, in addition to reload the scaler
conversion matrix at the same time.

The TFU can copy from raster, UIF, and SAND input images to UIF output
images, with optional mipmap generation. This will certainly be
useful for media EGL image input, but is also useful immediately for
mipmap generation without bogging the V3D core down.
For now we only run the queue 1 job deep, and don't have any hang
recovery (though I don't think we should need it, with TFU). Queuing
multiple jobs in the HW will require synchronizing the YUV coefficient
regs updates since they don't get FIFOed with the job.

why TFU is AUTH, clarify the syncing docs, drop the unused TFU

vc4_plane_atomic_async_check() was only based on the

We are about to change that to properly support underscan, and, in order

In vc4_plane_atomic_async_update(), we no longer call
vc4_plane_atomic_check() since vc4_plane_mode_set() has already been
called in vc4_plane_atomic_async_check(), and we don't need to allocate
a new LBM region (we reuse the one from the current state).
Note that we now have to manually update each field of the current
plane state since it's no longer updated in place (not sure we have
to sync all of them, but it's harmless if we do).

The only remaining instance of drm_modeset_lock_all_ctx() is in
