Many monitor supports two or more interfaces, such as HDMI and VGA.
They may also have two EDIDs: one for analog display and the other
for digital display. However, the analog one may not include the
information about bpc and color format. For example, the HP P24v
G4 Monitor has two EDIDs:
Analog:

For the display route: eDP -> TR5521 -> VGA, the color format and bpc
information can not be parsed from the analog EDID. To adapt to this
case, we set the default bpc to 8 and the default color format to
DRM_COLOR_FORMAT_RGB444.

The filter function helps to filter out the interfering signals in
the input waveform, whose width is less than the filter window with
specific width in nansecond.

The filter function helps to filter out the interfering signals in
the input waveform, whose width is less than the filter window with
specific width in nansecond.
For pwm v1, one controller can only enable filter for one channel
at the same time. It can be used for capture and IR input modes.
For pwm v4, each channel can independently enable filter function.
It can be applied in capture, biphasic counter and IR input modes.

If a new wb commit is too close to the timing of wb dma complete,
clearing the wb intr status will lose the wb dma complete status.
In this case, the software process is as follows:
vop2_wb_commit() -> vop2_wb_irqs_enable() -> Clear wb intr ->
vop3_sys_isr()/vop2_isr() -> vop2_read_and_clear_wb_irqs()
Since we had cleared the intr in vop2_wb_irqs_enable(), the value read
by vop2_read_and_clear_wb_irqs() is 0, and we have lost the interrupt
status.

The drm_writeback_queue_job() function takes ownership of the passed
job and requires the caller to manually set the connector state
writeback_job pointer to NULL.
Therefore, there is no need to clear the writeback_job again.

possible_clones is used to indicate which other encoders can share
a CRTC with the current encoder. The default logic is that an encoder
can exclusively occupy one CRTC. However, in scenarios such as writeback
or connector mirroring, we can support multiple encoders sharing one
CRTC, hence this logic is introduced.
If less this commit, the writeback or connector mirror will commit
failed at the drm_atomic_check_valid_clones(), which is introduced by
the following commit:

to load the link, the link will be reset and the RC side needs to
