On an MST unplug, the MST topology manager state needs to be cleared
so it can properly destroy the current topology. But since the mst
active state is cleared prematurely in the driver, this call is
skipped and on a subsequent plug-in, the topology manager ends up
using stale topology from previous configuration. Incorrect RAD
values are used for sideband, causing them to fail.
This change fixes the order of operations, so the topology manager
state is properly updated on unplug. It also removes a duplicate
hpd notification to usermode.

The ROI commands are sent with an asynchronous command transfer wait.
If the queued CMD DMA wait for done gets scheduled before the DSI
controller timing engine programming, the later will be blocked waiting
on the ctrl_lock, which was acquired by the queued DMA wait for done work.
This effectively negates any advantage of having the async wait flag for
ROI commands blocking the main commit thread.
The change swaps this order to ensure that such a scenario never happens.

While hw resources allocation for an active display during modeset, avoid
dsc hw allocation switch by finding which dsc encoders are allocated
previously and allocate same dsc hw encoders. This helps in fixing underrun
issues in below scenario of dual display power ON/OFF.
Use case: Dual DSI display setup, both are DSC enabled, primary in video mode.
--> when both displays are in powered off, all hw block are free.
--> enable second dsi display
Since LM 0/1 marked for primary, LM 2/3 allocated along with DSC 0/1
--> enable primary display
LM 0/1 allocated with DSC 2/3 encoders
--> Now power off secondary DSI
DSC 0/1 are freed up
--> Immediate modeset on primary, DSC allocation switched
LM 0/1 and DSC 0/1 allocated. DSC 2/3 are freed up as per RM but
decoupling DSC 2/3 blocks with respective pingpong or intf is not done.
This is causing underruns on primary.
Tracking which DSC blocks are freed during resource switch and programming the
respective DSC control mux configuration is not feasible and not scalable as
any other display can allocate those blocks and would require synchronizing
across display threads. So approach taken is avoid dsc resource switch itself.

If an external display, such as DP, requests for the available
resources, resource manager (RM) will provide a count of all unused
mixers. If the primary/secondary display(s) are not active, the RM
will report the associated preferred mixers as free resources.
However, RM will not allow preferred mixers to be allocated to other
displays. DP driver could look at these available resources and assume
a high resolution mode is possible and fail during resource allocation.
This change updates the available resources info API to account for
primary/secondary preferences while exposing available resources.

MDSS INTF HW block does not generate vsync if controller
turns off the link clock prematurely. This leads to
frame trigger timeout and SDE driver triggers the retire
fence after 84ms to recover gracefully. A client may switch
source pipe from one CTL path to another CTL path based
on delayed retire fence. It can lead to other ctl path
hang. This can be resolved by resetting the lm blend
stages for each missing vsync frame trigger.

Commit Ie972a2e140adfd81c4e68df8e7bc69feaaca22e1 updated the dp
driver to extract the drm mode clock from timing parameters
instead of using the clock value provided by EDID to align the
behavior with DSI driver. But this results in incorrect clock
value if the refresh rate is not an integer value. For rates
such as 59.94 or 29.97, the calculated mode clock value would
be different from what is stipulated by EDID. This change
reverts the mode clock calculation to use the clock value
from EDID.
