scsi: ufs: rockchip,rk3576-ufshc: dt-bindings: Add new mphy reset item

2026-05-23T11:09:14+00:00

[ Upstream commit bdce3a69c578090dd5e3c77bcdaaca10c3a41e34 ] Add the mphy reset property to the devicetree bindings for the Rockchip RK3576 UFS host controller. The mphy reset signal is used to reset the physical adapter. Resetting other components while leaving the mphy unreset may occasionally prevent the UFS controller from successfully linking up with the device. This addresses an intermittent hardware bug where the UFS link fails to establish under specific timing conditions with certain chips. While difficult to reproduce initially, this issue was consistently observed in downstream testing and requires explicit mphy reset control for full stability. Although this change increases the maxItems for resets and adds a new entry (which technically alters the binding ABI), it does not break compatibility for existing Linux systems. The driver uses devm_reset_control_array_get_exclusive() to manage resets, allowing it to function correctly with both older Device Trees (without the mphy entry) and newer ones.

scsi: ufs: dt-bindings: Document bindings for SA8255P UFS Host Controller

2026-01-24T03:04:32+00:00

Document the device tree bindings for UFS host controller on Qualcomm SA8255P platform which integrates firmware-managed resources. The platform firmware implements the SCMI server and manages 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. The generic "qcom,ufshc" and "jedec,ufs-2.0" compatible strings are removed from the binding, since this firmware managed design won't be compatible with the drivers doing full resource management.

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

2025-10-30T03:03:15+00:00

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.
