Merge series from Louis Chauvet <louis.chauvet@bootlin.com>: This series adds the support for the omap-mcspi multi mode which allows sending SPI messages with a shorter delay between CS and the message. One drawback of the multi-mode is that the CS is raised between each word, so it can only be used with messages containing 1 word transfers and asking for cs_change. Few devices, like FPGAs, may easily workaround this limitation. The first patch removes the current implementation, which is working, but don't comply with what is asked in the spi transfer (The CS is raised by the hardware regardless of cs_change state). No drivers or board file use this implementation upstream. The second patch adds the implementation of the multi-mode, which complies with what is asked in the SPI message. The third patch is the suggested optimization for using MULTI mode in more situations.
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.
