Since spi-rockchip enables use_gpio_descriptors and the SPI_CONTROLLER_GPIO_SS flag, the spi subsytem may call set_cs() for spi devices with indexes above ROCKCHIP_SPI_MAX_CS_NUM Remove array cs_asserted[] which held a shadow copy of the state of the chip select lines with the only purpose of optimizing out rewriting a chip select line to the current state (no-op) This case is already handled by spi.c Signed-off-by: Luis de Arquer <luis.dearquer@inertim.com> Link: https://lore.kernel.org/r/d0a0c4b94f933f7f43973c34765214303ee82b77.camel@gmail.com Signed-off-by: Mark Brown <broonie@kernel.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.
