As per HW recommendation, FAL10_VETO_OVERRIDE register can
be programmed to disable FAL10 in alternate to disabling
uidle at the sspp level as disabling UIDLE controller will
only disable DPU traffic shaping and will not stop the
system from entering FAL10 state. This change programs
FAL10_VETO_OVERRIDE register during uidle disable and also
sets CTL_x_UIDLE_ACTIVE register to always one to avoid
race condition between different CTL paths.

With full DSC size of 20k, RT performance issues are seen due to the
stress created during larger prefill needed to fill up the 20k DSC buffer.
Limiting DSC size to 10k helps to mitigate these RT performace issues.
This change adds support for this based on new flag has_reduced_ob_max
in sde_mdss_cfg data structure. Flag has_reduced_ob_max has be set
true only on targets where its recommended.

This change adds pp_tx during DMS switch for sim panel to
prevent WD timer getting updated in middle of the frame and
creating early vsync which might result in ppdone timeout.
For non-sim panels, this tx wait is not required and is

During a force update of DSI clocks, the state of the byte and pclks are
toggled irrespective of the ref-count. This in addition with ASYNC
command wait can result in interrupt storm, if and when the clocks are
being toggled a previous command that was triggered using the ASYNC
wait flag fires an ISR. The interrupt status doesn't get cleared if
the ISR is being serviced with the clocks are off.
The change adds a check for pending queued commands before any force
update of DSI clocks.

Below is the sequence during which issue is observed
while using stale lut values:
1) Scaler block is enabled in the VIG pipe along with the
valid lut configuration.
2) Idle work gets scheduled and GDSC is turned off erasing
the saved lut values.
3) At the same time, userspace sends a commit assuming lut
values are still valid resulting in artifacts on the
screen.
In the plane state scaler config, only lut flag will be
reset for subsequent commits and remaining properties such
as filter cfgs, lut_idx etc. remains same. This change
caches the lut flag in sde plane whenever the lut is being
set and reuses this flag to handle above issue.

In an effort to reset the DP controller states on a disconnect, the
driver is issuing a SW reset to the controller. But SW reset on
the controller doesn't necessarily restore the controller to its
full reset state. It only resets part of the logic. So if for some
reason the MST streams were not disabled properly, ie. the slot
allocations were not reset properly in the controller, then a SW
reset would result in the DP controller raising state interrupts.
Since this SW reset is issued in the tail end of the disconnect
processing, the driver turns off all the clocks and also
removes the irq handler. This results in an interrupt storm at
the MDSS top level.
This change removes the SW reset on the disconnect path and
relies on the SW reset that already exists in the connect path
to restore controller state.

For panels with higher porches exceeding default prefill lines
alternate framedrops can occur if transfer-time exceeds RSC static
waketup time as actual prefill lines are considered in RSC static
wakeup timer calculation. This change ensures transfer-time is with

This change reinitializes the sde_crtc->mixers when CTL
datapath switch occurs during mode set and RM allocation
of CTL hw block is changed. This initialization is required
for CTL_LAYER programming to trigger on the new CTL allocated
from RM.
Issue case:
1. Primary Display is using CTL_0 and it is reserved.
2. Secondary Display is using CTL_1. On suspend, RM adds
CTL_1 into the free list.
3. External Display is powered on, RM allocates CTL_1 hw blk.
4. Secondary Display is powered on, RM allocated CTL_2 hw blk.
5. External Display is suspended/unplugged, RM adds CTL_1 into
the free list.
6. When any mode_set(say fps switch) occurs on secondary, RM
allocates new resources and CTL_1 is allocated.
sde_crtc->num_mixers is non zero, so all the layer programming
happens on CTL_2, but CTL_1_FLUSH bits are programmed causing
hw timeout issue.
