andrewm@0 2 * I2c_Codec.h
andrewm@0 3 *
andrewm@0 4 * Handle writing the registers to the TLV320AIC310x
andrewm@0 5 * series audio codecs, used on the BeagleBone Audio Cape.
andrewm@0 6 * This code is designed to bypass the ALSA driver and
andrewm@0 7 * configure the codec directly in a sensible way. It
andrewm@0 8 * is complemented by code running on the PRU which uses
andrewm@0 9 * the McASP serial port to transfer audio data.
