Chanho Park cc52e15397 scsi: ufs: ufs-exynos: Support ExynosAuto v9 UFS
Add support for the ExynosAuto v9 SoC. This requires controlling the UFS IP
shareability register via syscon and regmap.  The offset of the register
can be different according to the UFS instance and SoC specific offset
value. As a result, we need to get the offset value from DT property.

Unlike exynos7, this implementation has a different M-PHY setting which
must be configured via exynosauto_ufs_pre_link.

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 Restructured Text 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.
