Geert Uytterhoeven <geert+renesas@glider.be> 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!
