hi, every one I browse the MMC/SD driver of kernel 2.6.10 and one question confused me very much. How the driver detect the MMC card state,I mean whether card insert or pull out? I think there should be a gpio interrupt to detect the card insert & pull out action. then the ISR will notice MMC driver to do right process. In driver /mmc/davinci_mmc.c there is only one interrupt that is IRQ_MMCINT.This interrupt is not used for card detect. It is an internal interrupt tfor the data transfer.
while in another file driver/mmc/omap.c there are two interrupt , one is mmc_omap_switch_irq which used for detect the cover open or close. and another one is mmc_omap_irq which used for data transfer. Could anybody tell me the reason? Thanks ! _______________________________________________ Davinci-linux-open-source mailing list [email protected] http://linux.davincidsp.com/mailman/listinfo/davinci-linux-open-source
