Currently, during ctl reset in video mode, irq register or
unregister might result in race condition with vblank
enable/disable calls on event thread resulting in enable
cnt mismatch. This change adds mutex locks to avoid race
conditions in such cases.

In pstate_cmp the plane_state structures are accessed
without checking it is allocated or not, which leads to
null pointer dereference. To fix it NULL check is added.

Add changes to fix the null dereference in
drm_atomic_get_property caused by connector->state
being NULL. This change allows the drm_mode_config_reset
operation to happen before drm_dev_register to avoid this.
In current scenario, connector->state->crtc is being
accessed due to call to drm_mode_getconnector ioctl with
the drm_mode_config_reset operation pending.

Fix out of bound access that occurs when reading dsi
commands with custom non 4 bytes aligned payload.
When misaligned, the code is overfetching data due
to 32 bits reading constraint. This creates an offset
in receiving buffer. Using a local copy buffer large
enough to hold the extra bytes fixes the issue.

Move the hist irq handling out of callback function, i.e., the hw
interrupt irq_lock context, to avoid dead lock between crtc spin_lock
and irq_lock. This change also extends crtc spin_lock coverage in
_sde_cp_crtc_enable_hist_irq to prevent null pointer dereference on
event node, which can be deleted during crtc event de-registration.

This driver provides exposure adjustment function by Qcom SDE dim
layer without change panel hardware brightness to avoid PWM flicker
on OLED devices. Thanks to OnePlus' opensource code for inspiring
me to use dim layer.
Use expo_calc_backlight to remap brightness with hardware and SDE,
checking Disable Hardware Overlays in developer options if you face
blocks with differents brightness issue.

Add a sysfs mechanism to track the idle state of display subsystem.
This allows user space to poll on the idle state node to detect when
display goes idle for longer than the time set.

With how often these macros are used in frame commit hotpaths, the
drm_debug bitmask check adds measurably significant overhead during
continuous frame commits. Omit the debug logging code entirely if !DEBUG
and !DYNAMIC_DEBUG to fix it.

This change increases the kickoff timeout in doze and
doze suspend usecases. This avoids false timeouts seen
in doze due to rscc static wakeup configured at a different
fps from actual panel TE.

This commit was creating unnecessary wakeup sources in root with illegal names containing spaces
For example "Listen [0-9] Audio Service"
Listen [0-9] Audio Service are common dai links defined in individual SOC specific codec files
and as these dai links are registed on msm-lse-client platform they were being created as a file
in linux root with illegal spaces in their name.
So, avoid creating wakeup sources with such names as they are not needed for anything critical
Fixes: wakeup_stats denials
Side Effects: None
This reverts commit b8348e7cb7a90a82ef9d75cc605b039f6bf7e7e9.
