From Kalama, the HW scheduler abstracts the low level
PP_DONE/WB_DONE interrupts and generates a common
CTL_DONE interrupt per hw ctl. This saves the software
the irq latency delays to process the frame complete
operations when multiple encoders are involved.
If supported, this change enables and waits for the
CTL_DONE interrupt instead of PP_DONE and WB_DONE.
This change adds support to wait for CTL_DONE irq in
only command mode panels as we don't drive two WB blocks
with single CTL.

Currently, writeback frame-triggers are serialized by default. Add
logic to support the different frame-trigger modes which can be set
through the connector property or encoder debugfs node.
- default: waits for frame(N-1) completion (wb-done-irq) before
configuring current frame(N) and releases the commit-thread on
frame-start (ctl-start-irq)
- posted-start: no previous frame(N-1) completion wait. Configures
frame(N) and releases the commit-thread on frame-start (ctl-start-irq)
- serialize: no previous frame(N-1) completion wait. Configures frame(N)
and releases the commit-thread on frame(N) completion (wb-done-irq)
(wb-done-irq) before configuring the next frame.
Restrict wb posted-start support only for MDSS 9.x+ targets, with older
targets defaulted to default-mode.

Avoid drm vblank on/off for virtual displays to allow drm framework to

In addition, avoid vblank callback registration for concurrent writeback
encoder.

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.

In the current code for finding the qsync min fps for a
mode, entire mode list is iterated which involves acquiring
dsi display_lock. During conn tx debugfs commands, if
qsync min fps is required, we try to acquire dsi
display_lock twice which results in hang state. This change
adds qsync min fps value in dsi_display_mode_priv_info
struct in order to get the qsync fps from the
msm_display_mode present in connector state instead of
looping through all the modes to find the mode qsync fps.

Delayed work items may touch HW registers. If these work items
run while HW is not owned by this VM it will lead to invalid
access. This happens in video mode as HAL does not disable idle
power-collapse in this mode. It can also happen with ESD status
if lastclose or TUI transition failure occurs.
Although there is a contract with user mode to turn off certain
features, kernel cannot rely on it to always do the right thing.
Prevent potential crashes from certain corner cases by
cancelling all delayed work items when the HW ownership is
transferred.
