MIPI DSI:
- Add "vsys_lcm_reg" regulator support and setup the "mt6357_vsim1_reg",
to power the pannel plugged to the DSI connector.
- Setup the Display Parallel Interface.
  - Add the startek kd070fhfid015 pannel support.

HDMI:
- Add HDMI connector support.
- Add the "ite,it66121" HDMI bridge support, driven by I2C1.
- Setup the Display Parallel Interface.

status is always okay, unless it's disabled.

Can we please get an actually readable name for this node?

Just a suggestion (you're free to rename however you want)

drive-strength = <4> is just fine....! :-)

extra blank line, please remove.

Did you run dtbs_check?!? :-)

Yes without error, here my command:
dt-validate -s Documentation/devicetree/bindings arch/arm64/boot/dts/mediatek/mt8365-evk.dtb

Also I've done a "make dtbs_check" just to be sure, nothing wrong on mt8365-evk.dtb.

For you, what is the issue please ?
