mmc: extend and rename cd-gpio helpers to handle more slot GPIO functions

2012-07-11T03:04:04Z

GPIOs can be used in MMC/SD-card slots not only for hotplug detection, but also to implement the write-protection pin. Rename cd-gpio helpers to slot-gpio to make addition of further slot GPIO functions possible. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Chris Ball

mmc: simplify mmc_cd_gpio_request() by removing two parameters

2012-03-27T16:20:14Z

Calculate the IRQ number, using gpio_to_irq() and use fixed flags: trigger on both edges. This makes two out of four arguments of the mmc_cd_gpio_request() function redundant. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Chris Ball

mmc: add a generic GPIO card-detect helper

2012-01-12T04:58:45Z

This patch adds a primitive helper to support card hotplug detection on platforms, where a GPIO, capable of producing interrupts, is used for detection of card-insertion and -removal events. Signed-off-by: Guennadi Liakhovetski Signed-off-by: Chris Ball
