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!

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
