[Why & How]
Due to how pmfw fills out the table when dcfclk states are disabled,
using dcfclk based clk table would cause a no read situation.
Revert the change to prevent underflow until a better solution is coded.

[WHy & How]
Unbounded requesting is unsupported on pipe split modes
and this change prevents us running into such a situation
with wide modes.

Workstation application ANSA/META v21.1.4 get this error dmesg when
running CI test suite provided by ANSA/META:
[drm:amdgpu_gem_va_ioctl [amdgpu]] *ERROR* Couldn't update BO_VA (-16)
This is caused by:
1. create a 256MB buffer in invisible VRAM
2. CPU map the buffer and access it causes vm_fault and try to move
it to visible VRAM
3. force visible VRAM space and traverse all VRAM bos to check if
evicting this bo is valuable
4. when checking a VM bo (in invisible VRAM), amdgpu_vm_evictable()
will set amdgpu_vm->evicting, but latter due to not in visible
VRAM, won't really evict it so not add it to amdgpu_vm->evicted
5. before next CS to clear the amdgpu_vm->evicting, user VM ops
ioctl will pass amdgpu_vm_ready() (check amdgpu_vm->evicted)
but fail in amdgpu_vm_bo_update_mapping() (check
amdgpu_vm->evicting) and get this error log
This error won't affect functionality as next CS will finish the
waiting VM ops. But we'd better clear the error log by checking
the amdgpu_vm->evicting flag in amdgpu_vm_ready() to stop calling
amdgpu_vm_bo_update_mapping() later.
Another reason is amdgpu_vm->evicted list holds all BOs (both
user buffer and page table), but only page table BOs' eviction
prevent VM ops. amdgpu_vm->evicting flag is set only for page
table BOs, so we should use evicting flag instead of evicted list
in amdgpu_vm_ready().
The side effect of this change is: previously blocked VM op (user
buffer in "evicted" list but no page table in it) gets done
immediately.
v2: update commit comments.

[Why]
Currently, we don't have code path to release remote dc_sink when unplug
MST hub from the system. After few times hotplug, we hit the limition of
maximum number of remote dc_sink and can't light up new connected monitor
anymore.
[How]
Releasing all remote dc_sink at dm_helpers_dp_mst_stop_top_mgr() was
removed by previous patch. Restore it.

[Why]
When hotplug or unplug happens, each stream disabled one by one, and then
enable any alived streams. Link phy and payload table is cleared when 1st
stream is disabled. That causes the error message pops up when disable 2nd
stream. There is no active stream after link_rate is cleared.
After all streams are disabled, link will be trained again and link rate is
assigned to any alived streams.
Therefore there is no harm for the error message that represents invalid
link rate value in the atomic reset transitional time period.
[How]
Downgrade the log level from ERROR to DEBUG.

[Why]
Hotplugging the VGA side of some DP/VGA adapters caused the display to
light up with the wrong (non-native) resolution.
This is caused by the adapter misbehaving by reporting the wrong number
of downstream ports when the VGA side is unplugged (reports 1 instead of
0), but only if the SINK_COUNT DPCD register is read more than once.
[How]
To work around the adapter behavior, remove the sink if link is
detected, but EDID cannot be read.

TGL+ and newer platforms don't support RPS up and low interruption
limits.
It is not used for broadwell and newer plaforms that supports
execlist but here making sure that it is explicit not used even in
debug scenarios.

In the past we had a need to differentiate TGL U and TGL Y, there
was a different voltage swing table for each subplatform and some PCI
ids of this subplatforms are shared but it turned out that it was a
specification mistake and the voltage swing table was indeed the same
but we went ahead with that patch because we needed to differentiate
TGL U and Y from TGL H and by that time TGL H was embargoed so that
was the perfect way to land it upstream.
Now the embargo for TGL H is long past and now we even have
INTEL_TGL_12_GT1_IDS with all TGL H ids, so we can drop this PCI root
check and only rely in the PCI ids to differentiate TGL U and Y from
TGL H that actually has code differences.
Besides the simplification this will fix issues in virtualization
environments where the PCI root is virtualized and don't have the same
id as actual hardware.
v2:
- add and set INTEL_SUBPLATFORM_UY

In order to fill the drm_display_info structure each time an EDID is
read, the code currently will call drm_add_display_info with the parsed
EDID.
drm_add_display_info will then call drm_reset_display_info to reset all
the fields to 0, and then set them to the proper value depending on the
EDID.
In the color_formats case, we will thus report that we don't support any
color format, and then fill it back with RGB444 plus the additional
formats described in the EDID Feature Support byte.
However, since that byte only contains format-related bits since the 1.4
specification, this doesn't happen if the EDID is following an earlier
specification. In turn, it means that for one of these EDID, we end up
with color_formats set to 0.
The EDID 1.3 specification never really specifies what it means by RGB
exactly, but since both HDMI and DVI will use RGB444, it's fairly safe
to assume it's supposed to be RGB444.
Let's move the addition of RGB444 to color_formats earlier in
drm_add_display_info() so that it's always set for a digital display.

panels
Some devices use e.g. a portrait panel in a standard laptop casing made
for landscape panels. efifb calls drm_get_panel_orientation_quirk() and
sets fb_info.fbcon_rotate_hint to make fbcon rotate the console so that
it shows up-right instead of on its side.
When switching to simpledrm the fbcon renders on its side. Call the
drm_connector_set_panel_orientation_with_quirk() helper to add
a "panel orientation" property on devices listed in the quirk table,
to make the fbcon (and aware userspace apps) rotate the image to
display properly.

Currently we just leave the old gunk lying around in the crtc
state when userspace asks us to fully disable the crtc. That
doesn't match what the state would be had we never even enabled
the crtc in the first place. So let's make this consistent and
call intel_crtc_prepare_cleared_state() for disabled crtcs as well
(excluding bigjoiner slaves of course which have had their state
copied from the master).
I actually already did this once in commit fff13e63a141 ("drm/i915:
Clear most of crtc state when disabling the crtc") but then
commit 19f65a3dbf75 ("drm/i915: Try to make bigjoiner work in atomic
check") undid it all :(
