The change adds register mapping of MDP_INTF_[1/2]_TEAR_INT_COUNT_VAL
register to DSI controller. This allows for the controller to read the
line count and frame count of the read pointer during trigger and
successful transfer of DMA command.
To enable the debug feature:
echo 1 > /d/<panel_name>/dsi-ctrl-0/enable_cmd_dma_stats.
To disable the debug feature
echo 0 > /d/<panel_name>/dsi-ctrl-0/enable_cmd_dma_stats.
To read line count value:
cat /d/<panel_name>/dsi-ctrl-0/cmd_dma_stats.

The change allows for configuring a command DMA window during which
the command is triggered. The DMA window must not intersect with the
MDP tear check window. Once the command transfer is successful, the
trigger control needs to reset to the default DMA trigger specified
by the panel.

The default PWM gpio pin mode was not right for PWM backlight
control. If needs to use PWM backlight, must config the

During a dynamic mode switch if the DSI clocks need to be changed,
it would result in a sequence of clock off and on operations. If
this happens after a partial update even though the commands are
sent with an asynchronous wait flag, the clock off forces the commit
thread to wait till the DSI command wait_for_done thread is
scheduled and completed. The change ensures that the clock change is
the first operation that occurs during pre kickoff.

This change add right only pu support by allowing the dsc to be
flushed when one of the dsc is getting disabled. Since the crtc
swaps the mixers in case of right only partial update, this change
fixes the active display mask passed to encoder so that always the
left only dsc gets programmed. This change also fixes layer mixer
configuration where only one layer mixer is driving the partial
update, the other mixer's configuration is disabled.

When LTM is turning off, user space will turn off LTM histogram and
then wait for LTM hist off event from driver to change the state
from offpending to off. But if device enters IPC during this time,
driver will not notify user space with LTM hist off event and LTM
will stuck in offpending state. This change remove the check
before LTM hist off event notification to avoid LTM state stuck issue.
