H Hartley Sweeten	5ca6518832	mmc: cd-gpio: Include header to pickup exported symbol prototypes ... Include the linux/mmc/cd-gpio.h header to pickup the prototypes for the two exported symbols. This quiets the sparse warnings: warning: symbol 'mmc_cd_gpio_request' was not declared. Should it be static? warning: symbol 'mmc_cd_gpio_free' was not declared. Should it be static?

Guennadi Liakhovetski	c9b0546a59	mmc: simplify mmc_cd_gpio_request() by removing two parameters ... 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.

Guennadi Liakhovetski	349ab52446	mmc: add a generic GPIO card-detect helper ... 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.
