mainlining shenanigans
49d7d695ca
By design of the currently available native set_cs callback, the CS de-assertion will be done only if it's required by the corresponding controller capability. But in order to pre-fill the Tx FIFO buffer with data during the SPI memory ops execution the SER register needs to be left cleared before that. We'll also need a way to explicitly set and clear the corresponding CS bit at a certain moment of the operation. Let's alter the set_cs function then to also de-activate the CS, when it's required.

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.
