Add minimal driver for Fairchild FXL6408 8-bit I2C-controlled GPIO expander using the generic regmap based GPIO driver (GPIO_REGMAP). The driver implements setting the GPIO direction, reading inputs and writing outputs. In addition to that the FXL6408 has the following functionalities: - allows to monitor input ports for data transitions with an interrupt pin - all inputs can be configured with pull-up or pull-down resistors Datasheet: https://www.onsemi.com/download/data-sheet/pdf/fxl6408-d.pdf Signed-off-by: Emanuele Ghidoli <emanuele.ghidoli@toradex.com> Co-developed-by: Francesco Dolcini <francesco.dolcini@toradex.com> Signed-off-by: Francesco Dolcini <francesco.dolcini@toradex.com> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> [Bartosz: order includes alphabetically] Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@linaro.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.
