Looks like a patch for the gpiolib is also > needed... ok. Take your time. It turns out that the infos I had were a bit misleading. I've been told the mmc driver was using some gpios and the gpios are GPIO_1_0/1_1 and GPIO_1_7/1_8... which are in fact the esdhc1 and esdhc2 CD and WP. This means : - with proper iomux configuration, WP detection is working fine - I should still be able to test WP on GPIO Thanks, Arnaud -- To unsubscribe from this list: send the line "unsubscribe linux-mmc" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
