Why is there a mismatch between your author name and signed off name?

Is label mandatory? Doesn't seem so?

Rest LGTM.

Please don't thread new versions off existing version. b4 helps you with
getting these things right, please check go/upstream for more details.

Even if it's clear what this is, I would prefer if you described the
hardware a little bit in your commit message.
"Rb3Gen2 has a HDMI connector, connected to DSI via a LT on i2cX.... reset and
irq pins comes from x and y. Describe this."

There's a stray tab here, please run checkpatch --strict on your

We want to keep nodes sorted (by address if applicable, otherwise
alphabetically on node names and on labels). "mdss_dsi" < "mdss_edp".

So please move this up where it belongs.

I'd expect a 2 here, so please document why this is 8.

My internal gitconfig is not configured correctly. Fixed in v3.

Moved the dsi nodes on top of edp. Didn't realise this.

No. V3 was still sent as a reply. Please fix the way you are sending
the patches. It has nothing to do with the git config.

The choice is either fix the dts or fix the binding.

My bot found new DTB warnings on the .dts files added or changed in this
series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings
are fixed by another series. Ultimately, it is up to the platform
maintainer whether these warnings are acceptable or not. No need to reply
unless the platform maintainer has comments.

If you already ran DT checks and didn't see these error(s), then
make sure dt-schema is up to date:

  pip3 install dtschema --upgrade


New warnings running 'make CHECK_DTBS=y qcom/qcs6490-rb3gen2.dtb' for jr3ble6sxr5mr6cvm6ldvpyk5j4rucj3xy6vbha6ttoecte3d7@llu6qf6oasuc:
