Thanks for the reviews, patches 1-3
`strncpy` is deprecated for use on NUL-terminated destination strings [1].
We should prefer more robust and less ambiguous string interfaces.
A suitable replacement is `strscpy_pad` due to the fact that it
guarantees NUL-termination on the destination buffer whilst maintaining
the NUL-padding
[WHY]
edid_override and drm_edid_override_connector_update, according to drm
documentation, should not be referred outside drm_edid.
[HOW]
Remove and replace them accordingly. This can tested by IGT's
kms_hdmi_inject test.

In order to generalize the node names, the DMA-related nodes
corresponding to MT8183 MDP3 need to be corrected.

Modeset mutex unlock is missing in drm_dp_mst_detect_port function.
This will lead to deadlock if calling the function multiple times in
an atomic operation, for example, getting imultiple MST ports status
for a DP MST bonding scenario.

Certain chips can combine several components to form complex virtual
units with advanced functions.
These components require simultaneous configuration of their MODs and
clocks.

Hello,
Upgrading to Linux 6.5 on a Lenovo ThinkPad L570 (Integrated Intel HD
Graphics 620 (rev 02), Intel(R) Core(TM) i7-7500U) results in a blank
screen after boot until the display manager starts... if it does start
at all. Using the nomodeset kernel parameter seems to be a workaround.
Similarly to the drm_exec_test module, the drm_modes_test
shows the following output on dmesg on load:
[ 5556.674834] KTAP version 1
[ 5556.674841] 1..1
[ 5556.675317] KTAP version 1
[ 5556.675321] # Subtest: drm_modes_analog_tv
[ 5556.675323] # module: drm_modes_test
[ 5556.675327]
After setting up the second set of MMSYS (VPPSYS1), it is necessary
to have a corresponding second set of MUTEX (MUTEX2) to assist in
handling SOF/EOF.

The Monolithic Power (MPS) MP3309C is a WLED step-up converter, featuring a
programmable switching frequency to optimize efficiency.
The brightness can be controlled either by I2C commands (called "analog"
mode) or by a PWM input signal (PWM mode).
This driver supports both modes.

The amount of MDP3 driver probes is determined by the registered
clocks of MMSYS.
Since MT8195 MDP3 utilizes VPPSYS0 and VPPSYS1, it's necessary to
prevent multiple driver registrations.
