Remove DMA_ATTR_IOMMU_USE_LLC_NWA and DMA_ATTR_IOMMU_USE_UPSTREAM_HINT
attributes as they are no longer needed since io-coherency is enabled.
Passing this attribute is a no op since buffer is io-coherent and will
be mapped with a write allocate policy contradicting intention
of that attribute.

Drm file is not set to NULL after freeing it from drm
release. This can result in use-after-free issues in
some scenarios. Add a mutex lock and other proper null
checks to prevent such issues.

Early wakeup ioctls from perf HAL driver can access display HW
registers and come as a sideband to atomic commits. Since the
atomic validate checks are not part of this code path it's
possible for HW access to occur during a trusted UI session.
Prevent this whenever the HW is not under this VM's ownership.
Also, move the VM ownership check for the register/deregister
event ioctl to cover both the CRTC and connector events since
new connector events are being added which can access HW.

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.

frame complete timeouts are fixed and can be much lower than
a vsync incase of low refresh rate display. Compute timeouts
based on refresh rate for low refresh rate displays.

SDE IRQ callback can run in parallel thread to modeset after removing
pp_done wait before pre_modeset.
If cur_master is cleared in encoder enable function and irq callback
is triggered at the same time, the irq callback could not be handled
properly as cur_master is NULL.
So remove clearing cur_master in encoder enable function to avoid the
race condition between modeset and irq callback.

Currently the DP driver always uses a compression ratio of 3, if
DSC is enabled. So if the sink supports 30bpp, the compressed
output is set to 10bpp. But since the hardware supports
compressing this to 8bpp, it would require less link bandwidth
than 10bpp compressed output. For compliance testing, the
test equipment limits the link bandwidth based on the most
efficient compression ratio and for some resolutions there
is not enough link bandwidth for 3:1 compression.
This change always sets the compression output to 8bpp to
minimize the link bandwidth utilization.

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.

dma_buf_get_flags is deprecated. Rather than using its updated API, avoid
checking flags and instead default to non secure context bank always.
Logic is already in place to detach from non secure and attach to secure
if needed based on plane property.
This change also removes the check for cached buffers since moving forward
all buffers will be cached so there is no need for this.
