d46c9286e5 disp: msm: sde: update uidle wd timer load value and fal1 threshold
Update the uidle wd timer load value to 18. This change will allow
a 15us wd timer per hardware recommendation.

Update fal1 threshold value to take the minimum of 15 or the
current setting which takes line time and target idle time into
consideration. The target idle time is also being updated from 10us to
40us.

690139ccd1 disp: msm: sde: serialize rm reserve for check only commit
During back to back mode set, current driver logic fails
atomic check during resource allocation with test only if
previous commit also with modeset, has tagged resources for
allocation but did not commit the resources yet. Since client
invoking atomic check before previous mode set commit complete
is an expected scenario now, instead of failing atomic check,
this change allows resource allocation for next commit also go
through by pollong till the first mode set is complete.

44cde01fc7 disp: msm: sde: manage vblank refcount concurrency
Vblank refcount can reach out of sync with below case
 1. event_thread triggers the vblank_enable
 2. commit_thread triggers the modeset
   2.a modeset resets the vblank refcount with mode_set
 3. event_thread triggers the vblank_disable

Event 2.a resets the vblank refcount and vblank disable
request after 2.a is going to fail. This can be fixed
by avoiding concurrency between mode_set call and vblank
request.

06ab29478d disp: msm: sde: avoid physical encoder disable(s) in trusted VM
VM switches during TUI usecase are expected to be seamless i.e without
display reset. In SDE language, this translates to respective display
drivers not tearing down the HW pipeline while releasing the HW.

In Primary VM, this taken care by keeping the DRM pipeline alive when
TUI is active.

In Trusted VM, since the client creates and destroys the display per
session, checks are needed to bypass the physical encoder disable(s).

f946219084 disp: msm: sde: update sspp multi rect programming
Current SDE driver allows staging of rect1 only configuration. When a
real plane is disabled sspp multi rect configuration is not updated.
This can lead to iommu faults and ping pong timeouts as framebuffer of
disabled plane is unmapped. This change fixes it by updating multi rect
config accordingly when a plane is disabled.

935af8104a disp: msm: sde: avoid MDSS register access during boot in trusted VM
Trusted VM will be assigned MDSS HW access dynamically only on TUI
use case start boundary. So, any HW access during the boot sequence
will result in stage2 faults. But SDE driver initializes few HW
blocks during the boot up sequence. This change fixes them by either
skipping those accesses, if those registers expected to be programmed
by the Primary VM or postponing those accesses until the HW is
assigned.
