The simulation case uses dp_mst_sim_detect_port which
calls the drm detect port function after checking
the mst state. The non simulation case calls the drm
function directly.
This leads to cases in the disconnect path where
connectors are detected while being unregistered.
This solution merges the simulation and non simulation
cases by using the same detect port function, where a
check for mst state is performed before calling the
drm function.

LM size does not need to be reprogrammed on every frame. Add
a check to only reprogram it when the size changes (or coming
out of power collapse). Some color processing features require
an update when this happens as well (i.e. resolution switch,
partial update, or dest scaler reconfigure). This patch allows
for notifying CP of the updated dimensions when a change occurs.

This change disables the border color on the layer mixer,
based on the caller's request. This is required to totally
disconnect the layer mixer hardware when it is not
participating in blending the pixels. Having empty blendstage
but border color enabled, allows Layer mixer hw to produce
border pixels even when blend stage is empty.

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 debugfs api for mst control is a multi stage process where the
connector id is selected using the mst_con_id node, which is then
used on other commands such as edid_modes_mst for mode switch.
During mode switch control, the mode is set using the current id
for a display and then the switch is initiated through an unplug
and replug. But on an unplug the connector is destroyed and a new
id is assinged for that display on the subsequent plug. This
change detects this scenario and updates the cached connector id
with the id from the newly created connector.

On hpd low signaling, if MST is enabled, then the dp driver should
send the uevent to usermode and wait for the displays to be turned
off before destroying the connectors. In the current mst driver,
hpd low handling is a monolithic step. This change breaks this
into two separate callbacks into the mst driver so the display
driver can wait for usermode completion between these two steps.
When processing hpd low in sim mode, the mst driver uses the drm
framework's the port detection function. When hpd unplug is signaled
to the usermode, it checks the port status before disabling it. But
since the port hasn't been destroyed yet, the framework reports that
the port as still connected. This causes the driver to timeout while
waiting for the the displays to be disabled. This change adds a
wrapper which will report the port status as disconnected when hpd
low is signaled.

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.
