[PATCH V3 0/4] Add UFS support for x1e80100 SoC

[PATCH V3 0/4] Add UFS support for x1e80100 SoC

[Pradeep P V K]

Add UFSPHY, UFSHC compatible binding names and UFS devicetree
enablement changes for Qualcomm x1e80100 SoC.

Changes in V3:
- Update all dt-bindings commit messages with concise and informative
  statements [Krzysztof]
- keep the QMP UFS PHY order by last compatible in numerical ascending
  order [Krzysztof]
- Remove qcom,x1e80100-ufshc from select: enum: list of
  qcom,sc7180-ufshc.yaml file [Krzysztof]
- Update subject prefix for all dt-bindings [Krzysztof]
- Add RB-by for SoC dtsi [Konrad, Abel, Taniya]
- Add RB-by for board dts [Konrad]
- Link to V2:

[PATCH V3 1/4] dt-bindings: phy: qcom,sc8280xp-qmp-ufs-phy: Add QMP UFS PHY compatible

[Pradeep P V K]

Document QMP UFS PHY compatible for x1e80100 SoC. Use SM8550 as a
fallback since x1e80100 is fully compatible with it.

"jedec,ufs-2.0" was set to const in dt-bindings, dropping now will lead

No, it is not ok. You cannot have errors/warnings and I think it is
obvious that you need to fix everything, not only DTS.

incorrect from the start anyway, so there is no ABI breakage. But make sure you
justify it in the description.
