We could do something like what the AT91SAM9G20 platform does with ifdefed code for the mic (in that case there's no mic support in the hardware but the CODEC is in a low density package so it's relatively common for users to lift pins to flying wire in a mic) I guess. -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
