[PATCH 1/2] arm64: dts: qcom: monaco: add lt8713sx bridge with displayport

[Vishnu Saini]

Monaco-evk has LT8713sx which act as DP to 3 DP output
converter. Edp PHY from monaco soc is connected to lt8713sx
as input and output of lt8713sx is connected to 3 mini DP ports.

Two ports are available in mainboard and one port
is available on Mezz board.

lt8713sx is connected to soc over i2c0 and with reset gpio
connected to pin6 of ioexpander5.

Enable the edp nodes from monaco and enable lontium lt8713sx
bridge node.

The labels should be unique, is there any silkscreen or similar that would
be a good candidate?

Wrongly placed, at least at next I am checking now. Look at Kconfig or
just run savedefconfig.

Cross checked this few rescent changes were added configs in same file.
verified added config is present in generated .config file and lt8713sx driver is compiled with it.
Let me know if need to add this config is another file or at different place.

So did you run `make savedefconfig`? If you do not understand review
then at least follow what I asked for...

This generate a minimal defconfig containing only non‑default options.
A defconfig file is generated in my root dir, CONFIG_DRM_LONTIUM_LT8713SX is part of this generated defconfig.
shall i update arch/arm64/configs/defconfig with generated defconfig and verify ?

In which place is the config entry present in defconfig and is it the

Thank you for the clarity, I thought lexicographical order is followed here.
savedefconfig generated in below order, i will follow same in v4 patch.
Sorry Krzysztof i completely misunderstood the question.

CONFIG_DRM_LONTIUM_LT8912B=m
