808a4ae5fa vgaarb: Use ACPI HID name to find integrated GPU
Commit 3d42f1ddc4 ("vgaarb: Keep adding VGA device in queue") assumes
the first device is an integrated GPU. However, on AMD platforms an
integrated GPU can have higher PCI device number than a discrete GPU.

Integrated GPU on ACPI platform generally has _DOD and _DOS method, so
use that as predicate to find integrated GPU. If the new strategy
doesn't work, fallback to use the first device as boot VGA.

Originally when using pm_runtime_put, there's a chance that the runtime
suspend hook will be run after the following anx7625_bridge_mode_set
call, resulting in the display_timing_valid field to be cleared, and the
following power on fail.

Change all pm_runtime_put to pm_runtime_put_sync, so all power off
operations are guaranteed to be done after the call returns.

510b281488 drm/i915/adl_p: Tx escape clock with DSI
Today when the DSI controller is paired with the Combo-PHY it
uses the high-speed (HS) Word clock for its low power (LP)
transmit PPI communication to the DPHY. The interface signaling
only changes state at an Escape clock frequency (i.e. its
effectively running on a virtual Tx Escape clock that is controlled
by counters w/in the controller), but all the interface flops are
running off the HS clock.

This has the following drawbacks:

 * It is a deviation from the PPI spec which assumes signaling is
   running on a physical Escape clock
 * The PV timings are over constrained (HS timed to 312.5MHz vs.
   an Escape clock of 20MHz max)

This feature is proposing to change the LP Tx communication between
the controller and the DPHY from a virtual Tx Escape clock to a physical
clock.

To do this we need to program two "M" divisors. One for the usual
DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV register and one for MIPIO_DWORD8.

For DSI_ESC_CLK_DIV and DPHY_ESC_CLK_DIV registers the "M" is calculated
as following

Nt = ceil(f_link/160) (theoretical word clock)
Nact = max[3, Nt + (Nt + 1)%2] (actual word clock)
M = Nact * 8

For MIPIO_DWORD8 register, the divisor "M" is calculated as following

M = (Nact - 1)/2

835c176cb1 drm/i915: Introduce MBUS relative dbuf offsets
The dbuf slices are going to be split across several MBUS units.
The actual dbuf programming will use offsets relative to the
MBUS unit. To accommodate that we shall store the MBUS relative
offsets into the dbuf_state->ddb[] and crtc_state->plane_ddb*[].

For crtc_state->wm.skl.ddb however we want to stick to global
offsets as we use this to sanity check that the ddb allocations
don't overlap between pipes.

c61cdbdbff drm/scheduler: Fix hang when sched_entity released
Problem: If scheduler is already stopped by the time sched_entity
is released and entity's job_queue not empty I encountred
a hang in drm_sched_entity_flush. This is because drm_sched_entity_is_idle
never becomes false.

Fix: In drm_sched_fini detach all sched_entities from the
scheduler's run queues. This will satisfy drm_sched_entity_is_idle.
Also wakeup all those processes stuck in sched_entity flushing
as the scheduler main thread which wakes them up is stopped by now.

v2:
Reverse order of drm_sched_rq_remove_entity and marking
s_entity as stopped to prevent reinserion back to rq due
to race.

v3:
Drop drm_sched_rq_remove_entity, only modify entity->stopped
and check for it in drm_sched_entity_is_idle
