The Altera SPI driver currently uses the spi-bitbang infrastructure for transfer queue management, but non of the bitbang functionality itself. This is because when the driver was written this was the only way to not have to do queue management in the driver itself. Nowadays transfer queue management is available from the SPI driver core itself and using the bitbang infrastructure just adds an additional level of indirection. Switch the driver over to using the core queue management directly. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
