commit3e5ec1db8bupstream. When improving the CS GPIO support at core level, the SPI_CS_HIGH has been enabled for all the CS lines used for a given SPI controller. However, the SPI framework allows to have on the same controller native CS and GPIO CS. The native CS may not support the SPI_CS_HIGH, so they should not be setup automatically. With this patch the setting is done only for the CS that will use a GPIO as CS Fixes:f3186dd876("spi: Optionally use GPIO descriptors for CS GPIOs") Cc: <stable@vger.kernel.org> Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com> Link: https://lore.kernel.org/r/20191018152929.3287-1-gregory.clement@bootlin.com Signed-off-by: Mark Brown <broonie@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
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.
