[Why]
DCN3 has two gamut remap matrices. When using CSC adjustment the CM
remap is set to bypass and MPCC remap is used. However to bypass CM
some state in the context is modified and not restored correctly
resulting in subsequent calls to disable MPCC remap as well.
[How]
Fix logic for save/restore of remap enable flag when programming MPCC
remap matrix.

[Why]
Soft hangs occur when FreeSync is engaged since we utilize VUPDATE
(which doesn't fire when holding the pipe lock) to send back vblank
events when FreeSync is active.
[How]
The alternative (working) interrupt source for this mechanism is
VUPDATE_NO_LOCK. We already use this all other DCN revisions so align
dcn30 with those as well.

the page frame number of system memory mapped by the CPU. In preparation
for supporting large pages to be mapped by the GPU, process faults one

corner case where the input hmm_pfns array is not reinitialized after
hmm_range_fault() returns -EBUSY and must be called again.

It doesn't hurt to add the bridge in the global bridge list also for
platform specific dw-hdmi drivers which are based on the component
framework. This can be achieved by moving the drm_bridge_add() function
call from dw_hdmi_probe() to __dw_hdmi_probe(). A counterpart movement
for drm_bridge_remove() is also needed then. Moreover, since drm_bridge_add()
initializes &bridge->hpd_mutex, this may help those platform specific
dw-hdmi drivers(based on the component framework) avoid accessing the
uninitialized mutex in drm_bridge_hpd_notify() which is called in
dw_hdmi_irq(). Putting drm_bridge_add() in __dw_hdmi_probe() just before
it returns successfully should bring no logic change for platforms based
on the DRM bridge API, which is a good choice from safety point of view.
Also, __dw_hdmi_probe() is renamed to dw_hdmi_probe() since dw_hdmi_probe()
does nothing else but calling __dw_hdmi_probe(). Similar renaming applies
to the __dw_hdmi_remove()/dw_hdmi_remove() pair.

If the HW throws a curve ball and reports either en event before it is
possible, or just a completely impossible event, we have to grin and
bear it. The first few events, we will likely not notice as we would be
expecting some event, but as soon as we stop expecting an event and yet
they still keep coming, then we enter into undefined state territory.
In which case, bail out, stop processing the events, and reset the
engine and our set of queued requests to recover.
The sporadic hangs and warnings will continue to plague CI, but at least
system stability should not be compromised.

v3: Customised user facing message for forced resets from internal errors.

Perf implements a GPU delay (noa_wait) by looping until the CS timestamp
has passed a certain point. This use MI_MATH and the general purpose
registers of the user's context, and since it is clobbering the user
state it must carefully save and restore the user's data around the
noa_wait. We can verify this by loading some values in the GPR that we
know will be clobbered by the noa_wait, and then inspecting the GPR after
the noa_wait completes and confirming that they have been restored.

Apparently there are EDIDs in the wild with multiple DispID extension
blocks. Iterate through them all.
In one particular case the tile information is specicied in the
second DispID ext block, and since the current parser only looks
at the first DispID ext block we don't notice that we're dealing
with a tiled display.
While at it change a few functions to return void since we have
no use for the errno.

Apparently EDIDs with multiple DispID ext blocks is a thing, so prepare
for iterating through multiple ext blocks of the same type by
passing the starting ext block index to drm_find_edid_extension(). Well
also have drm_find_edid_extension() update the index to point to the
next ext block on success. Thus we should be able to call
drm_find_edid_extension() in loop.
