There are several vendor-specific versions of the DW SPI controllers, each of which may have some peculiarities with respect to the original IP-core. Seeing it has already caused adding flags and a callback into the DW SPI private data, let's introduce a generic capabilities interface to tune the generic DW SPI controller driver up in accordance with the particular controller specifics. It's done by converting a simple Alpine-specific CS-override capability into the DW SPI controller capability activated by setting the DW_SPI_CAP_CS_OVERRIDE flag.

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.
