You might want to check for updates in the omap tree though, or even ask on an omap-specific list: someone might have already implemented it but not pushed it to mainstream yet. -- Jean Delvare -- To unsubscribe from this list: send the line "unsubscribe linux-i2c" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
