HDCP authentication has strict timing requirements and if the
display is on static screen during this time, it is possible
that SDE removes the QOS vote when it detects static display,
thereby affecting the hdcp authentication process.
This change adds qos support in dp driver to vote exclusively
for DP. If valid QOS settings are provided in dtsi, then the
driver adds the vote when it starts authentication and removes
the vote when authentication is completed.

During an HPD, HDCP IRQ handler prints error log and exit
if HDCP state is inactive or authentication failure.
Inactive state is a benign error and auth failure will be
reported by hdcp kernel module. This change will downgrade

In ASYNC wait mode, next command kickoff can happen before previous command ISR execution is
completed in below sequence:
ASYNC command A -> triggered
dsi_ctrl_isr for command A -> fired and executed atomic_set(&dsi_ctrl->dma_irq_trig, 1);
wait_for_done for command A -> returns early as dsi_ctrl->dma_irq_trig is 1
ASYNC Command B -> triggered
wait_for_done for command B -> waiting for cmd_dma_done
dsi_ctrl_isr for command A -> executes complete_all(&dsi_ctrl->irq_info.cmd_dma_done);
wait_for_done for command B -> returns success incorrectly based on complete_all of previous
command isr and disable_status_interrupt() is not called.
This leads to refcount of dma_done going wrong and dsi_ctrl_isr is not enabled on suspend resume.
To fix this issue, mark command transfer successful only based on complete_all(cmd_dma_done). This
way disable_status_interrupt() will be always called either from dsi_ctrl_isr or wait_for_done().

If MST is enabled, the controller needs MST ACT to be
completed to successfully transition to 'Ready for Video'
state. The driver is sending ACT during the normal flow
when transitioning from link training to stream enable.
But it is not sending ACT, if a link maintenance is
triggered after stream enable. This change adds the ACT
update to the link maintenance call flow.

Currently RSC timer register programming is optimized for updating
only during timing param changes and not during RSC state changes
with same timing. Static wakeup time computation should consider
panel jitter for RSC clk state too, else it can result in RSC hang.
This change also removes extra logic for video mode prefil lines
computation for rsc config as video mode does not enable RSC solver.
Current issue scenario exposing the hang is in dual dsi display scenario
where RSC is in clock state and static wakeup time is programmed by
not considering panel jitter, after suspend/pmsuspend while waking up
if RSC switches to command state if primary enabled first and vsync
may arrive much early based on the panel jitter. RSC hw can not handle
if TE arrives earlier than static wakeup time causing RSC hang.

After an ESD failure, the PHY lanes and controller can be stuck in
an unknown state. This can result in interrupt storms and watchdog
failures, if these error states are not handled correctly. The following
change implements the below mechanism to avoid failures.
1) Disable error interrupts during an ESD reg read, which are re-enabled once
ESD check is successful.
2) On ESD failure, before turning off LP clocks, reset the PHY lanes and DSI
controller.
3) After the HS clocks are turned off, issue a PHY hard reset.
4) Before enabling/disabling error interrupts, clear the error status registers
as they are not cleared as part of controller reset.

When switching between 2 dongles/adapters it is possible
to have the same resolution with different link configuration.
Even though the pixel clock could be the same on replug, the
vco clock could be different depending on the link
configuration. Since the dp driver only exposes limited clocks
to the clock framework, in this specific scenario, the clock
driver is unable to recognize the change in source clock rate
and ends up skipping the clock reconfiguration.
This change adds support to park the pixel clocks on disable,
thereby forcing a reconfiguration on subsequent replug even
if the pixel clocks are the same.
