[PATCH v2 0/2] scsi: ufs: dt-bindings: Add compatibles for Nord UFS controller

[Shawn Guo]

This series documents the UFS host controller on Qualcomm Nord SoC.

Nord is a Qualcomm SoC series. Its UFS controller has a multi-queue
command (MCQ) register range in addition to the standard one,
both of which are required.

Nord also has an automotive variant, SA8797P, where the platform
firmware implements an SCMI server and manages UFS resources such as
the PHY, clocks, regulators and resets. As a result, SA8797P shares
the minimal OS-visible DT interface of SA8255P and uses it as the
fallback compatible

Changes in v2:
 - Keep the newline between compatible and reg in SA8797P patch
 - Link to v1: https://lore.kernel.org/all/20260420100416.1252983-1-shengchao.guo@oss.qualcomm.com/

[PATCH v2 1/2] scsi: ufs: dt-bindings: Add compatible for Nord UFS Host Controller

[Shawn Guo]

Document UFS Host Controller on Qualcomm Nord SoC. Like the Eliza SoC,
Nord has a multi-queue command (MCQ) register range in addition to
the standard one, making both reg entries required.

[PATCH v2 2/2] scsi: ufs: dt-bindings: Add compatible for SA8797P UFS Host Controller

[Shawn Guo]

From: Deepti Jaggi <deepti.jaggi@oss.qualcomm.com>

SA8797P is the automotive variant of the Nord SoC. Like SA8255P, its
platform firmware implements an SCMI server that manages UFS resources
such as the PHY, clocks, regulators and resets via the SCMI power
protocol. As a result, the OS-visible DT only describes the controller's
MMIO, interrupt, IOMMU and power-domain interfaces, making SA8255P the
appropriate fallback compatible.

Applied to 7.2/scsi-staging, thanks!
