SDE plane src/dst size is uninitialized and programmed to hw when
only color format is changed. This change will only configure hw
when src/dst size is calculated.

This change will wrap the 'hpd_off' flag with pluggable displays.
In non-pluggable display case 'hpd_off' flag prevents disabling
of HPD clocks and hence display subsystem doesn't got into suspend
state.

If the splash clean up is trigger, the MDP core power on call should
be skipped. MDP core already turned on in sde_kms_hw_init() if splash

This change fixes an unclocked hdmi register access while going
to suspend state.
When splash is enabled on HDMI interface & we are going to turn
on the hdmi bridge power. Context of sde_hdmi connector is found
to be NULL because connector was not initialized yet and we never
called sde_hdmi_core_enable which enables hpd clocks.
Now when going to suspend system would be calling clock unprepare
for clocks which were never enabled. Hence hdmi clock gets unbalanced
and resulted in unclocked access to one of the hdmi register during
disabling vblank.
Adding struct sde_hdmi as a member of struct sde_hdmi_bridge and remove
dependency on sde connector to get the hdmi display object.

Update the sde_dbg_dump function to only dump event log
entries up to the time the dump is initiated, and increase
the number of recorded event log entries.
This places a limit on the total number of entries that are
output to the dmesg log even if more entries would have been
added while the dump is executing (e.g., interrupt events),
while still allowing the extra events to be recorded properly.

This change adds debugfs nodes for debugging underruns,
after this change following commands are supported:
1. To enable the underrun ftrace:
echo 1 > /d/tracing/events/sde/sde_encoder_underrun/enable
2. To enable feature that disables the ftraces once the
underrun happens:
echo 1 > /d/dri/0/debug/dbg_ctrl
3. To enable the panic in the device when underrun happens:
echo 2 > /d/dri/0/debug/dbg_ctrl
4. To enable both of the above options:
echo 3 > /d/dri/0/debug/dbg_ctrl

In concurrency test, smmu map failure appears in a low possibility.
This is caused by virtual address conflict. Display driver calls
different smmu map APIs to do map with the same domain, while the
virtual address allocation happens separately, one in dmp-mapping.c,
and another one is in msm_gem_vam.c. This could not gurantee the
virtual addresses by different callers are different in the same
mmu domain, if they are the same, the virtual address will possibily
be mapped twice, hence conflict happens.
The change is to fix this:
1. Remove the map calling for early splash buffer from msm_smmu_map.
2. Introduce one new map API early_splash_map/unmap, dedicated for
memory mapping for early splash usercase.

Display thread processes the work assigned by HAL for
screen update. Current logic selects the thread priority
to default and causes the frame drop. This patch moves
the display thread to realtime priority to process the display
work items at realtime. Event thread must follow the
display thread priority to avoid frame_pending counters
beyond 2.

In the function ttm_page_alloc_init, kzalloc call is made for variable
_manager, we need to check its return value, it may return NULL.

[ Upstream commit a121027d2747168df0aac0c3da35509eea39f61c ]
On my GP107 when I load nouveau after unloading it, for some reason the
GPU stopped sending or the CPU stopped receiving interrupts if MSI was
enabled.
Doing a rearm once before getting any interrupts fixes this.

commit 458d876eb869d5a88b53074c6c271b8b9adc0f07 upstream.
We only support vga_switcheroo and runtime pm on PX/HG systems
so forcing runpm to 1 doesn't do anything useful anyway.
Only call vga_switcheroo_init_domain_pm_ops() for PX/HG so
that the cleanup path is correct as well. This mirrors what
radeon does as well.
v2: rework the patch originally sent by Lukas (Alex)

commit 06998a756a3865817b87a129a7e5d5bb66dc1ec3 upstream.
Similar to commit e10aec652f31 ("drm/edid: Add 6 bpc quirk for display
AEO model 0."), the EDID reports "DFP 1.x compliant TMDS" but it support
6bpc instead of 8 bpc.
Hence, use 6 bpc quirk for this panel.

The sde encoder merges the flush for both controller but
does not configure the split_flush_enable on mdp_top.
This causes stage-1 fault or vsync_failure because right
side lm/sspp are not getting updated on each update. This
patch enables the split_flush only for pingpong split case
and also checks the vsync status on correct register.
