These are controlled through sysfs. Just tested with "i2cdetc -y -r 0" that crashes with "BUG: soft lockup - CPU#0 stuck for 22s!" according to the docs (IMX23RM.pdf) the interrupts for I2C are 26 and 27 that why I assigned these two in the dts. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
