[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.

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
same as the one in your patch? That was the question that Krzysztof
asked in the first email, which you seem to ignore.

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.

[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 of these 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 or ioexpander5.

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

Comment start/stop markers should have a space after/before them

dt-bindings already describe what it is

Similarly, you can move these settings to monaco.dtsi and keep them as
defaults since 99.99% of I2C users will share them

Is it ok if i update this in a different series, similar other nodes like qup_i2c1_default
added in monaco-evk.dts?

No, I don't want you to introduce something "wrong" only because you
don't want to run git commit --amend

I see you've now sent a v2 just 7 minutes after asking this question.
Should I interpret that as you expecting me to drop everything and rush
to respond to your queries immediately, or do you not care about my
feedback anyway?

Apologies, for quickly raising the new patch, i thought of correcting this
in next V3 patch if you ask for.
I am new contributor to the upstream community, just now i setup mutt and learned a bit about
sending reply to the emails and V2 patch was already validated that's why i submitted it.

monaco.dtsi already have below node except drive-strength and  bias-pull-up.
tlmm {
	qup_i2c0_data_clk: qup-i2c0-data-clk-state {
		pins = "gpio17", "gpio18";
		function = "qup0_se0";
	};
};
I will add drive-strength and  bias-pull-up in monaco-evk.dts, let me know if this is ok?

It's okay. Just please try not to do it again - it's really an anti-pattern.

That should be fine. Other SoC DTSIs do that already

This is good, you're describing the role of LT8713sx and how it's
connected on the board. Thank you for taking the time to do so!

I think one aspect that's worth pointing out on its own is the
placement of the mini DP ports. You do capture it, but the fact that
we have two on the EVK and one on the expansion board is "hidden" there
in the middle of the paragraph.
I think extracting this part of the message into its own paragraph would
improve the commit message further.

Would it be possible to add dp-connector nodes and wire them up to the
&lt8713sx, like I did in sa8295-adp.dts?

This should be bridge@4f.

Also, unless we need to reference this from a overlay there's no need to
give it a label.

This comment explains what "lontium,lt8713sx" is. The binding call tell
me that, so the value of this comment would be for you to tell us what
it is used for on this particular board - and if that's obvious you can
omit the comment.

In addition to using an of_graph to describe the connectors that this is
wired to, it would be nice to have a port describing the relationship to
the DP controller here as well - so we know where the signal is coming
from.

Would that be possible to add?
