Sorry, only just seen this patch.
Please do not do this!
The entire lrc_desc_pool entity is being dropped as part of the update
to GuC v70. That's why there was a recent patch set to significantly
re-organise how/where it is used. That patch set explicitly said - this
is all in preparation fo
This series adds support for generic eDP panel over aux_bus.
These changes are dependent on the following series in order:

This patch adds support for generic eDP sink through aux_bus. The eDP/DP
controller driver should support aux transactions originating from the
panel-edp driver and hence should be initialized and ready.
The panel bridge supporting the panel should be ready before the bridge
connector is initializ
The source device should ensure the sink is ready before proceeding to
read the sink capability or performing any aux transactions. The sink
will indicate its readiness by asserting the HPD line. The controller
driver needs to wait for the hpd line to be asserted by the sink before
performing any a
The panel-edp enables the eDP panel power during probe, get_modes
and enable. The eDP connect and disconnect interrupts for the eDP/DP
controller are directly dependent on panel power. As eDP display can be
assumed as always connected, the controller driver can skip the eDP
connect and disconnect i
The interrupt register will still reflect the connect and disconnect
interrupt status without generating an actual HW interrupt.
The controller driver should not handle those masked interrupts.

The aux_bus support with the dp_display driver will enable the dp
resources during msm_dp_modeset_init. The host_init has to return early
if the core is already initialized to prevent putting an additional vote
for the dp controller resources.

The panel-edp driver modes needs to be validated differently from DP
because the link capabilities are not available for EDP by that time.

Two digits are swapped in the AUO B133UAN01 panel id (0x8495 instead
of 0x8594). This went initially unnoticed because the panel is still
detected, though it is set up with a conservative default timing. Fix
the digit swap.

The invalid EDID block filtering uses the number of valid EDID
