gpio: add GPIO support for F71882FG and F71889F
This patch adds support for the GPIOs found on the Fintek super-I/O chips F71882FG and F71889F. A super-I/O is a legacy I/O controller embedded on x86 motherboards. It is used to connect the low-bandwidth devices. Among others functions the F71882FG/F71889F provides: a parallel port, two serial ports, a keyboard controller, an hardware monitoring controller and some GPIO pins. Note that this super-I/Os are embedded on some Atom-based LaCie NASes. The GPIOs are used to control the LEDs and the hard drive power. Changes since v3: - Use request_muxed_region to protect the I/O ports against concurrent accesses. Changes since v2: - Remove useless NULL setters for driver data. Changes since v1: - Enhance the commit message by describing what is a Super-I/O. - Use self-explanatory names for the GPIO register macros. - Add a comment to explain the platform device and driver registration. - Fix gpio_get when GPIO is configured in input mode. I only had the hardware to check this mode recently... Signed-off-by: Simon Guinot <simon.guinot@sequanux.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
