H A D | host.h | 28f52482 Tue Jun 17 09:17:15 CDT 2008 Anton Vorontsov <avorontsov@ru.mvista.com> mmc: add support for card-detection polling
Some hosts (and boards that use mmc_spi) do not use interrupts on the CD line, so they can't trigger mmc_detect_change. We want to poll the card and see if there was a change. 1 second poll interval seems resonable.
This patch also implements .get_cd() host operation, that could be used by the hosts that are able to report card-detect status without need to talk MMC.
