| * gpio: return -ENOTSUPP if debounce cannot be setLinus Walleij2013-09-041-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It appears some drivers are using gpio_set_debounce() opportunistically, i.e. without knowing whether it works or not. (Example: input/keyboard/gpio_keys.c) to account for this use case, return -ENOTSUPP and do not print any warnings in this case. Took a round over the other gpio_set_debounce() consumers to make sure that none of them are relying on the returned error code to be something specific.

| * gpio: improve error path in gpiolibLinus Walleij2013-09-031-16/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At several places the gpiolib will proceed to handle a GPIO descriptor even if it's ->chip member is NULL and no gpiochip is associated. Fix this by checking that both the descriptor cookie *and* the chip pointer are valid. Also bail out earlier with more specific diagnostic messages on missing operations for setting as input/output or debounce. ChangeLog v1->v2: - Also return -EIO on gpiod_set_debounce() with missing operations in the vtable - Fix indentations.

| * gpio: add GPIO support for F71882FG and F71889FSimon Guinot2013-08-303-0/+480
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=16004 Registers 'IdeaPad Slidebar' input device and /sys/devices/platform/ideapad_slidebar/slidebar_mode for switching slidebar's modes. Now works on: IdeaPad Y550, Y550P. May work on (testing and adding new models is needed): Ideapad Y560, Y460, Y450, Y650, and, probably, some others.
