Merge patch series "ufs: Add support for AMD Versal Gen2 UFS"

2025-10-30T03:03:15Z

Ajay Neeli says: This patch series adds support for the UFS driver on the AMD Versal Gen 2 SoC. It includes: - Device tree bindings and driver implementation. - Secure read support for the secure retrieval of UFS calibration values. The UFS host driver is based upon the Synopsis DesignWare (DWC) UFS architecture, utilizing the existing UFSHCD_DWC and UFSHCD_PLATFORM drivers.

scsi: ufs: amd-versal2: Add UFS support for AMD Versal Gen 2 SoC

2025-10-30T03:00:49Z

Add support for the UFS host controller on the AMD Versal Gen 2 SoC, built on the Synopsys DWC UFS architecture, using the UFSHCD DWC and UFSHCD platform driver. This controller requires specific configurations like M-PHY/RMMI/UniPro and vendor specific registers programming before doing the UIC_LINKSTARTUP.

scsi: ufs: host: mediatek: Adjust sync length for FASTAUTO mode

2025-10-22T01:36:45Z

Set the sync length for FASTAUTO G1 mode in the UFS Mediatek driver. This ensures the sync length meets minimum values for high-speed gears, improving stability during power mode changes.

scsi: ufs: ufs-sysfs: Expose UFS power info

2023-11-15T15:23:55Z

Having UFS power info available in sysfs makes it easier to tell the state of the link during runtime considering we have a bunch of power saving features and various combinations for backward compatibility.

scsi: ufs: Split the drivers/scsi/ufs directory

2022-05-20T00:27:37Z

Split the drivers/scsi/ufs directory into 'core' and 'host' directories under the drivers/ufs/ directory. Move shared header files into the include/ufs/ directory. This separation makes it clear which header files UFS drivers are allowed to include (include/ufs/*.h) and which header files UFS drivers are not allowed to include (drivers/ufs/core/*.h). Update the MAINTAINERS file. Add myself as a UFS reviewer.
