- Link to V4:
  https://lore.kernel.org/all/20260106154207.1871487-1-pradeep.pragallapati@oss.qualcomm.com

Changes in V4:
- Update ufs@ with ufshc@ in SoC dtsi [Mani]
- Retain complete change history in cover letter [Dmitry]
- Remove "jedec,ufs-2.0" compatible from ufshc dt-bindings
  and SoC dtsi files [Krzysztof, Mani]
- Remove RB-by tag from Krzysztof and AB-by tag from Mani on
  UFSHC dt-binding file as it has changes and needs re-review.
- Add RB-by for QMP UFS PHY dt-binding [Krzysztof]
- Add RB-by for SoC dtsi [Konrad, Abel, Taniya, Mani]
- Add RB-by for board dts [Konrad]
- Link to V3:
  https://lore.kernel.org/all/0689ae93-0684-4bf8-9bce-f9f32e56fe06@oss.qualcomm.com
 
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:
  https://lore.kernel.org/all/20251231101951.1026163-1-pradeep.pragallapati@oss.qualcomm.com

Changes in V2:
- Update all dt-bindings commit messages to explain fallback
  to SM8550 [Krzysztof]
- Pad register addresses to 8-digit hex format [Konrad]
- Place one compatible string per line [Konrad]
- Replace chip codenames with numeric identifiers throughout [Konrad]
- Fix dt_binding_check error in UFSHC dt-bindings [Rob]

- This series is rebased on GCC bindings and driver changes:

[PATCH V5 1/3] dt-bindings: ufs: qcom,sc7180-ufshc: Add UFSHC compatible for x1e80100

[Pradeep P V K]

Add UFS Host Controller (UFSHC) compatible for x1e80100 SoC. Use
SM8550 as a fallback since x1e80100 is fully compatible with it.

Qualcomm UFSHC is no longer compatible with JEDEC UFS-2.0 binding.
Avoid using the "jedec,ufs-2.0" string in the compatible property.

NAK

You CANNOT take DTS patches. This is different subsysytem - look at the
subject prefix.
