262099e94a disp: msm: replace kzfree with kfree
This change replaces kzfree with kfree as kzfree has been
renamed.

While moving to the latest 5.10 tip, additional small changes
were required to resolve compilation issues:

set_dma_ops has moved from dma-mapping to dma-map-ops header.
This change includes the new header file required.

drm_panel_add returns void, this change removes the expected
return value check.

drm_prime_pages_to_sg takes an additional parameter. This change
passes in the drm_device pointer the function is looking for.

Remove an unused variable in sde_crtc vblank function.

d3d3f808d4 disp: msm: sde: use pp dsc api only if hw supports
This change checks the capabilities of pingpong block to
check if it needs to call the pingpong api to enable or
disable the dsc. Certain hw versions do not have support
in pingpong block to enable/disable the dsc instead the
dsc block itself have the hooks to control the DSC.

6daf1c58e7 disp: msm: sde: use wr_ptr interrupt instead of ctl_start
SDE driver triggers the frame and waits for the
ctl_start interrupt for command mode display. This interrupt
provides confirmation that hardware has picked up the
frame. Retire fence signaling is associated with
this interrupt and it is sent at the rd_ptr interrupt
after ctl_start. Due to lut dma delay, ctl_start interrupt
may be trigger before rd_ptr or after rd_ptr. SW manages
this complexity and handle retire fence for different cases
with 500us threshold logic.

This change replaces the ctl_start interrupt with wr_ptr
interrupt by programming it to trigger at 1st write line
count. This is guaranteed to come every time and it is close
to rd_ptr interrupt. That allows retire fence trigger at
wr_ptr interrupt and simplifies the SW logic. CRTC commit
thread would be held slightly longer with this change
as the wr_ptr is always close to rd_ptr and after
ctl_start.

734a80305a drm/msm/sde: Add global dither memory dump range
The global dither memory range can not be accessed from outside.
So the patch fixs this issue through add global dither memory range
to valid range.
