When histogram buffer is queued by driver client, during the display
commit buffer has to be submitted to hardware. Currently driver is
waiting for previous histogram to finish before submitting the new
buffer. This can cause the histogram to be invalid, change updates the

This changes the method of esd detection at tx timeout
from TE to panel status read for panels having status
read as default method.
When ESD is triggered, even if spurious TE interrupt fires
after resetting the panel gpio, driver correctly follows
the recovery after esd failure.

Reserve LM in the sequence of primary-peer and then
primary-peer again until all required LM are reserved.
Searching sequence will not change for single/dual LM
reservation. For single LM reservation it will return
right after the first primary LM is found. For dual LM
reservation it will return after the first primary-peer
pair is found.
The logic can also work for triple/quad or any number
of LM reservetion and make sure that all the reserved
LMs are in pairs except the last one if total LM number
is odd.

When a 4LM topology is used each plane attached to a CRTC
is tagged with a L/R layout value and an offset value
depending on where destination X coordinate lands on the display.
The layout information is used to determine SSPP to LM
pair mapping and local coordinate space.
This change also handles source-split and Z-order
validation checks for planes staged on different mixer
pairs.

Setup blendstages is done per LM but FETCH_PIPE_ACTIVE is per CTL.
Overloading mixer blendstage setup with fetch pipe logic can lead
to HW programming errors. Refactor the logic for setting
FETCH_PIPE_ACTIVE by adding a new op that allows caller to provide
a bitmask of all pipes required to be active on this CTL. This new
logic includes support for:
- 4LM use-cases, staging pipes for all LMs within a CRTC
- Demura fetch-pipe without need for tracking via active_cfg (removed)
Also, lower the cyclomatic complexity in setup_blendstages by moving
the logic for obtaining the mixer config settings in to a helper
function.
