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!
