Introduce functions to manipulate UFS inline encryption hardware in line with the JEDEC UFSHCI v2.1 specification and to work with the block keyslot manager. The UFS crypto API will assume by default that a vendor driver doesn't support UFS crypto, even if the hardware advertises the capability, because a lot of hardware requires some special handling that's not specified in the aforementioned JEDEC spec. Each vendor driver must explicitly set hba->caps |= UFSHCD_CAP_CRYPTO before ufshcd_hba_init_crypto_capabilities() is called to opt-in to UFS crypto support.

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.
