It's enabled because the initial bringup of the device uses the write sequencer which relies on the MCLK, and more practically because devices of the era that the driver was written were rarely able to manage the external clock. For the initial driver submission I suggest fixing the MCLK rate for 44.1kHz and leaving it on all the time under the control of the machine driver, I'll make sure someone from Wolfson enhances the WM8903 driver so that the machine driver can be made more flexible. -- 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
