Unmult feature is currently using offsets from previous targets.
This leads to unexpected alpha transparency errors on screen.
This change updates the new offsets based on hw version and
retains the original offsets for backward compatibility.

When all instances of driver fd's are closed by user-space client, drm driver
will be closed. When last close of driver is called, custom reset properties
api will be called where driver should cache the properties that it wants to
clear. Current behavior of color processing driver is to clear hardware
configuration instead of caching which can cause crashes if clocks are off.
Change updates the driver to cache the pending disable and update hardware
during display commit.

Currently mode fixup function is called multiple times
in the same commit. This causes invalid combination of
DSI mode flags to be set when there is an RFI change
with proch compensation feature enabled.
This change modifies the mode switch condition for DMS
to compare internal dsi mode and flags and fixes the
dynamic clock change detection by using a single variable.

Currently when RFI is used on a video mode panel the horizontal or
vertical front porch values can be adjusted to maintain a constant FPS.
When this feature is enabled, driver is not propagating the new
htotal or vtotal values to usermode for accurate BW and MDP clock
calculation, which may lead to underrun in some usecase.
This change publishes beforehand all the RFI related timing
such as compensation type, hfp or vfp and clock values for
each mode for accurate BW and clock calculation.

The brightness value from backlight device is OS brightness, not panel

Demura memory region parsing incorrectly uses the display number
as an extraction index, causing failures in dual panel cases.
Update Demura memory region parsing to always use index 0 during
extraction as each defined region is designed to only declare

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.

In current implementation, register dump memory is allocated
separately for each range and block. When register dumps are
added to minidump, this will generate multiple minidump bin files
after a crash. Changes are made to allocate all the required
register dump memory once. When register dumps are added to
minidump, this will generate only one minidump bin file.
Use kvzalloc and kvfree to allocate and free this memory as
the memory needed to allocate is around 126 KB. Update the
allocation of debug buses also to kvzalloc and kvfree.

wb_atomic_check has set in_clone_mode to true in commit N,

In PM resume with CWB concurrency usecase, crtc pointer in
conn->state is NULL since drm_mode_config_reset operation is
performed on pm_resume. This change relies on conn_mask in
new_crtc_state for primary connector retrieval and also adds
get_num_lm_from_mode callback to DSI for LM count retrieval
from dsi panel topology. Existing get_mode_info api cannot
retrieve the topology info because mode->priv_info is NULL.
This occurs as WB encoder is added in the drm encoder_list
before primary encoder, introduced as part of commit d28ebf05f4
("disp: msm: sde: populate WB display encoder list before dsi").

When calculating the maximum bpp that can be supported for the
link configuration and mode, currently the driver is not
accounting for the FEC overhead. When FEC is enabled, the
link bandwidth available for the video stream is reduced and
therefore it needs to be included in the calculation.

FEC is a link specific configuration and should be configured before
the MST streams are enabled. Currently, the driver is configuring FEC
for each stream and in a case where the first stream is compressed and
the second stream is uncompressed, it enables FEC before the first
stream is enabled but ends up disabling FEC when the second stream is
enabled.
This change splits FEC/DSC configuration into separate functions and
skips FEC configuration for the second stream.

Some panels may require that the DSI link returns to the low-power
stop state (LP11) after transmission of every line. If a panel
requires that the DSI link returns to LP11, apply the LP11
insertion between lines feature.
This change adds support to
- Disable the command mdp burst mode
- Enable mdp idle ctrl
- Program the No. of dsi pclk cycles of idle time to
insert between command mode mdp packets. The idle time
must be long enough to cover the time link takes to
switch between HS to LP11 mode.

This change avoids upstream drm issuing drm_atomic_commit in

atomic_check failures due to atomically unstaging each fb
from plane_state and committing remaining planes on hardware.
a) This patch moves the state operations for setting crtc to
connector state to a helper api.
b) This patch clears any dim_layers present in the crtc_state
as part of null commit.
c) This patch removes any framebuffers attached to a drm_file
in msm_preclose whose refcount is not managed by composer kill
inadvertently and issues null flush to hardware in such cases.
d) This patch handles msm_preclose as part of msm_release
operation since legacy feature is not supported
