[WHY & HOW]
Newer ASICs have different PSP footer sizes which lead to driver
failing to locate the DMCUB FW meta info, which in turn causes
improper DMCUB FW loading and causes DMCUB to crash.
Add support for custom PSP footer sizes and check 512B by default
as well.

The function dereferences amdgpu_dm_connector->dc_link early to
initialize verified_link_cap and dc, but later still checks
amdgpu_dm_connector->dc_link for NULL in the analog path.
This late NULL check is redundant, introduce a local dc_link pointer,
use it consistently, and drop the superfluous NULL check while using
dc_link->link_id.id instead.
The function uses dc_link at the very beginning without checking if it
is NULL. But later in the code, it suddenly checks if dc_link is NULL.
This check is too late to be useful, because the code has already used
dc_link earlier. So this NULL check does nothing.
We simplify the code by storing amdgpu_dm_connector->dc_link in a local
dc_link variable and using it throughout the function. Since dc_link is
already dereferenced early, the later NULL check is unnecessary and is
removed.
Fixes the below:
amdgpu_dm_connector_get_modes():
variable dereferenced before check 'amdgpu_dm_connector->dc_link'

[Why]
Some monitors perform rapid “autoscan” HPD re‑assertions right after a
disconnect or powersaving mode enablement. These appear as a quick
disconnect→reconnect with an identical EDID. Since Linux has no HDMI
hotplug detection (HPD) filter, these quick reconnects are seen as hotplug
events, which can unintentionally wake a system with DPMS off.
An example: https://gitlab.freedesktop.org/drm/amd/-/issues/2876
Such 'fake reconnects' are considered when the interval between a
disconnect and a connect is within 1500ms (experimentally chosen using
several monitors), and the two connections have the same EDID.
[How]
Implement a time-based debounce mechanism:
1. On HDMI disconnect detection, instead of immediately processing the
HPD event, save the current sink and schedule delayed work (default 1500ms)
2. If another HDMI disconnect HPD event arrives during the debounce period,
it reschedules the pending work, ensuring only the final state is processed.
3. When the debounce timer expires, re-detect the display and compare the
new sink with the cached one using EDID comparison.
4. If sinks match (same EDID), this was a spontaneous HPD toggle:
- Update connector state internally
- Skip hotplug event to prevent desktop rearrangement
If sinks differ, this was a real display change:
- Process normally with the hotplug event
The debounce delay is configurable via module parameter
'hdmi_hpd_debounce_delay_ms'.

Adds the missing @aconnector, @connector, and @force descriptions:
@aconnector – This is the DM (Display Manager) connector. It gives
access to the DRM connector, the DC link, and hotplug/poll state. The
code uses it to check the link, update the sink, and manage connector
state changes.
@connector – This is the main DRM connector given by the DRM core.
Inside the detect function, it is converted to amdgpu_dm_connector so we
can run DC link detection, either light or full.
@force – This flag tells the function whether to run a full detect
again. If false, we avoid heavy DAC load detect steps to prevent
flicker. If true, we force a re-detect even when we normally skip it.

commit 978fa2f6d0 ("drm/amd/display: Use scaling for non-native
resolutions on eDP") started using the GPU scaler hardware to scale
when a non-native resolution was picked on eDP. This scaling was done
to fill the screen instead of maintain aspect ratio.
The idea was supposed to be that if a different scaling behavior is
preferred then the compositor would request it. The not following
aspect ratio behavior however isn't desirable, so adjust it to follow
aspect ratio and still try to fill screen.
Note: This will lead to black bars in some cases for non-native
resolutions. Compositors can request the previous behavior if desired.

When a connection is established through DAC load detection,

commit 0887054d14 ("drm/amd: Drop abm_level property") dropped the
abm level property in favor of sysfs control. Since then there have
been discussions that compositors showed an interest in modifying
a vendor specific property instead.
So re-introduce the abm level property, but with different semantics.
Rather than being an integer it's now an enum. One of the enum options
is 'sysfs', and that is because there is still a sysfs file for use by
userspace when the compositor doesn't support this property.
If usespace has not modified this property, the default value will
be for sysfs to control it. Once userspace has set the property stop
allowing sysfs control.
The property is only attached to non-OLED eDP panels.

[Why]
The main reason common modes are added is for compatibility with
clone mode when a laptop is connected to a projector or external
monitor. Since commit 978fa2f6d0 ("drm/amd/display: Use scaling
for non-native resolutions on eDP") when non-native modes are picked
for eDP the GPU scalar will be used. This is because it is inconsistent
whether eDP panels have the capability to actually drive non-native
resolutions. With panels connected to other connectors this limitation
generally doesn't exist as we the EDID will advertise support for a
number of resolutions and monitors will use built in scaling hardware.
Comparing DC and non-DC code paths the non-DC code path only adds
common modes for LVDS and eDP whereas the DC codepath does it for
all connector types.
In the past there was an experiment done to disable common mode adding
for eDP and LVDS from commit 6d396e7ac1 ("drm/amd/display: Disable
common modes for LVDS") and commit 7948afb46a ("drm/amd/display:
Disable common modes for eDP") but this was reverted in
commit a8b79b0918 ("drm/amd: Re-enable common modes for eDP and
LVDS") because it caused problems with Xorg.
[How]
Only add common modes for eDP and LVDS for DC, matching the behavior
of non-DC.

Don't update DC stream color components during atomic check. The driver

stream color components. The DC stream color state will only be
programmed at commit time in the `atomic_setup_commit` stage.
It fixes gamma LUT loss reported by KDE users when changing brightness
quickly or changing Display settings (such as overscan) with nightlight
on and HDR. As KWin can do a test commit with color settings different
from those that should be applied in a non-test-only commit, if the
driver changes DC stream color state in atomic check, this state can be
eventually HW programmed in commit tail, instead of the respective state
set by the non-blocking commit.

On clients that utilize AMD_PRIVATE_COLOR properties for HDR support,
brightness sliders can include a hardware controlled portion and a
gamma-based portion. This is the case on the Steam Deck OLED when using
gamescope with Steam as a client.
When a user sets a brightness level while HDR is active, the gamma-based
portion and/or hardware portion are adjusted to achieve the desired
brightness. However, when a modeset takes place while the gamma-based
portion is in-use, restoring the hardware brightness level overrides the
user's overall brightness level and results in a mismatch between what
the slider reports and the display's current brightness.
To avoid overriding gamma-based brightness, only restore HW backlight
level after boot or resume. This ensures that the backlight level is
set correctly after the DC layer resets it while avoiding interference
with subsequent modesets.
