2012-07-21mmc: core: add WP pin handler to slot functionsGuennadi Liakhovetski1-0/+4
Card Write-Protect pin is often implemented, using a GPIO, which makes it simple to provide a generic handler for it. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Chris Ball <cjb@laptop.org>
2012-07-21mmc: add CD GPIO polling support to slot functionsGuennadi Liakhovetski1-0/+2
A simple extension of mmc slot functions add support for CD GPIO polling for cases where the GPIO cannot produce interrupts, or where this is not desired for some reason. Signed-off-by: Guennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: Chris Ball <cjb@laptop.org>
2012-07-10mmc: extend and rename cd-gpio helpers to handle more slot GPIO functionsGuennadi Liakhovetski1-0/+18
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 <g.liakhovetski@gmx.de> Signed-off-by: Chris Ball <cjb@laptop.org>
