Merge patch series "scsi: ufs: renesas: Add support for R-Car S4-8 ES1.2"

2025-03-11T01:36:30Z

Geert Uytterhoeven says: Hi all, Initialization of the UFS controller on R-Car S4-8 ES1.0 requires only static values. However, other UFS controller variants (R-Car S4-8 ES 1.2) require dynamic values, like those obtained from E-FUSE, and downloading firmware. Hence this patch series refactors the initialization code to prepare for this, and adds support for the UFS controller on R-Car S4-8 ES1.2. The accompanying DTS change is available at [1]. This has been tested on: - Renesas Spider with R-Car S4-8 ES1.0 (broken before/after), - Renesas S4 Starter Kit with R-Car S4-8 ES1.2 (works after). Thanks for your comments!

dt-bindings: ufs: Correct indentation and style in DTS example

2025-01-23T21:11:11Z

DTS example in the bindings should be indented with 2- or 4-spaces and aligned with opening '- |', so correct any differences like 3-spaces or mixtures 2- and 4-spaces in one binding. No functional changes here, but saves some comments during reviews of new patches built on existing code.
