[PATCH v6 0/2] arm64: dts: qcom: add initial support for Samsung Galaxy S22

[Violet]

Changes in v6:
- Remove debug features (bootargs, etc) that slipped in the v5 DTS
- Format and organize nodes correctly based on existing DTS, 
 move "status = "okay";" to the bottom always
- Solve "ddr_device_type" and "qcom,rmtfs-mem" warnings, the rest are
 from existing SoC .dtsi
- Disable buttons, ufs and other features for later revision

This is an automated instruction, just in case, because many review tags
are being ignored. If you know the process, you can skip it (please do
not feel offended by me posting it here - no bad intentions intended).
If you do not know the process, here is a short explanation:

Please add Acked-by/Reviewed-by/Tested-by tags when posting new versions
of patchset, under or above your Signed-off-by tag, unless patch changed
significantly (e.g. new properties added to the DT bindings). Tag is
"received", when provided in a message replied to you on the mailing
list. Tools like b4 can help here. However, there's no need to repost
patches *only* to add the tags. The upstream maintainer will do that for
tags received on the version they apply.

Do you know what these are connected to?

We tend to document it, see e.g. x1-crd.dtsi

Is that a hardware limitation? I thought these phones had the necessary
pins connected (for DeX)..

A newline before 'status' is good practice, file-wide

Thank you, I'll fix these issues on the next patchset. Indeed it is not a

hardware limitation, I just kept it USB 2.0 for now to avoid any

potential issues with 3.0.

How this can be v6? Someone (you?) sent last time v2?

Where is the rest of changelog? v1, v2, v3, v4, v5? Or at least lore
links to previous discussions and changelogs?

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


This patch series was applied (using b4) to base:
 Base: attempting to guess base-commit...
 Base: failed to guess base

If this is not the correct base, please add 'base-commit' tag
(or use b4 which does this automatically)
