2014-02-10pinctrl: at91: use gpiolib API to mark a GPIO used as an IRQJean-Jacques Hiblot1-0/+27
When an IRQ is started on a GPIO line, mark this GPIO as IRQ in the gpiolib so we can keep track of the usage centrally. Signed-off-by: Jean-Jacques Hiblot <jjhiblot@traphandler.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

2013-12-04gpio/pinctrl: make gpio_chip members typed booleanLinus Walleij1-1/+1
This switches the two members of struct gpio_chip that were defined as unsigned foo:1 to bool, because that is indeed what they are. Switch all users in the gpio and pinctrl subsystems to assign these values with true/false instead of 0/1.

2013-08-28pinctrl: Pass all configs to driver on pin_config_set()Sherman Yin1-19/+29
When setting pin configuration in the pinctrl framework, pin_config_set() or pin_config_group_set() is called in a loop to set one configuration at a time for the specified pin or group. This patch 1) removes the loop and 2) changes the API to pass the whole pin config array to the driver. It is now up to the driver to loop through the configs. This allows the driver to potentially combine configs and reduce the number of writes to pin config registers. All c files changed have been build-tested to verify the change compiles and that the corresponding .o is successfully generated.

2013-08-07pinctrl: at91: choose appropriate handler for level interruptsBoris BREZILLON1-2/+14
The current implementation handle both edge and level interrupts with the 'handle_simple_irq' handler. Level interrupts are active as long as the pin stays at the configured level (low or high). In this case we have to use 'handle_level_irq' which mask the interrupt until the handle has treated it.
