drivers: ufs: remove unused ufs_post_bind() declaration

2026-03-02T14:20:02Z

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 to include prototype of ufs_scsi_bind() function, so we can now safely remove such includes.

ufs: Disable UTP command timeout in slow mode

2026-03-02T14:19:17Z

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.

scsi: ufs: renesas: Remove register control helper function

2026-01-27T20:46:44Z

After refactoring the code, ufs_renesas_reg_control() is no longer needed, because all operations are simple and can be called directly. Remove the ufs_renesas_reg_control() helper function, and call udelay() directly. Ported from Linux kernel commit 855bde8ce5bc ("scsi: ufs: renesas: Remove register control helper function") with replaced readl_poll_timeout_atomic() with readl_poll_sleep_timeout().

scsi: ufs: renesas: Add register read to remove save/set/restore

2026-01-27T20:46:44Z

Add support for returning read register values from ufs_renesas_reg_control(), so ufs_renesas_set_phy() can use the existing ufs_renesas_write_phy() helper. Remove the now unused code to save to, set, and restore from a static array inside ufs_renesas_reg_control().

scsi: ufs: renesas: Replace init data by init code

2026-01-27T20:46:44Z

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.
