2026-03-02drivers: ufs: remove unused ufs_post_bind() declarationJulien Stephan
Commit 067c1b033282 ("ufs: Call ufs_scsi_bind() from uclass .post_bind") inlined ufs_scsi_bind() into ufs_post_bind() as trivial device_bind_driver() call. ufs_scsi_bind() is no longer referenced anywhere in the codebase, so drop its declaration from include/ufs.h. Drivers used to include <ufs.h> to include prototype of ufs_scsi_bind() function, so we can now safely remove such includes.

2026-03-02ufs: Disable UTP command timeout in slow modePadmarao Begari
When the UFS controller is operating in slow (PWM) mode, the driver is disabled the timeout for UTP send commands. In high-speed mode, the timeout remains enabled to detect stalled or failed transfers. This change ensures reliable operation in slow mode, where command completion may take longer and timeouts are not required.

2026-01-27scsi: ufs: renesas: Replace init data by init codeYoshihiro Shimoda
Since initialization of the UFS controller on R-Car S4-8 ES1.0 requires only static values, the driver uses initialization data stored in the const ufs_param[] array. However, other UFS controller variants (R-Car S4-8 ES1.2) require dynamic values, like those obtained from E-FUSE. Refactor the initialization code to prepare for this. This also reduces kernel size by almost 30 KiB.

This patch has the goal to add support for DesignWare UFS Controller specific operations. This is based on linux kernel commit: "drivers/scsi/ufs/ufshcd-dwc.c: ufs: add support for DesignWare Controller" (sha1: 4b9ffb5a353bdee49f1f477ffe2b95ab3f9cbc0c) It is ported from linux kernel 6.11-rc1.

2024-10-14ufs: core: remove link_startup_again logicNeil Armstrong
The link_startup_again logic was added in Linux to handle device that were set in LinkDown state, which should not be the case since U-boot doesn't set LinkDown state are init, and Linux sets the device active in ufshcd_init() for the first link startup. ufshcd_set_ufs_dev_active(hba) is called at ufshcd_init() right before scheduling an ufshcd_async_scan that will call ufshcd_device_init() then ufshcd_link_startup(). The comment in probe says: /* * We are assuming that device wasn't put in sleep/power-down * state exclusively during the boot stage before kernel. * This assumption helps avoid doing link startup twice during * ufshcd_probe_hba(). */ we can assume the same from U-Boot. While it worked to far, it breaks link startup for Qualcomm Controllers v5, let's just remove the logic.

2024-10-14ufs: Add missing memory barriersBhupesh Sharma
Add missing wmb() and mb() barriers in the u-boot UFS core framework driver to allow registers updates to happen before follow-up read operations. This makes the barrier placement similar to the Linux UFS driver, synced from the Linux v6.9 release. Starting from the v6.10 release, the barriers were replaced with a register read-back in [1], this will ported to u-boot in a second time.
