Currently, in dsi_display_get_modes, priv_info, rates,
front_porches and pixel_clks_khz memory is allocated for each
timing node and the same memory is copied for each supported fps.
The values of front porches calculated to maintain constant fps for
each bit clk rate gets overwritten with the values for last fps in
the dfps list. But the values of front porches should be different
in case where DFPS and dynamic clock are both supported either by
vfp approach or hfp approach. To fix this, allocate memory
separately for each fps.

It needs to enabled in both uidle enable and disable cases.
CTL_x_UIDLE_ACTIVE is set to 0 only in cases where uidle configuration

Based on panel hardware support, display brightness levels can
be very high value. This high value display brightness cooling
device levels can cause exceeding PAGE_SIZE for cooling device stat
buffer. It leads to buffer failure for cooling device stat feature.
Limit display panel mitigation level max to 255. If hardware
supports more than 255, then scale brightness levels fit
into above limit.

This change deprecates idle notify work for video mode
since idle timer will be maintained by userspace.
As part of idle notify work, syscache state is changed from
CACHE_STATE_NORMAL to CACHE_STATE_PRE_CACHE along with
notifying to the userspace. This change removes
CACHE_STATE_PRE_CACHE in the state machine and state is
updated from CACHE_STATE_NORMAL to CACHE_STATE_FRAME_WRITE
whenever the cache property is set.

If there are any uncleared DP interrupts before deinitialing
and turning off the clocks, the interrupt might get stuck at
the MDP level and can't be cleared without turning the DP
clocks back on. To avoid this situation, this change clears
all the interrupts before turning off the clocks.

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

This change sends a notification to user mode after msm_drm
driver releases the mmio and irq resources on trusted vm transition
request. This is required as user mode has no other way to know
when the resources where actually released. User mode driver earlier

releasing the hw.

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.
