Initial commit.

+/*
+ * I2c_Codec.h
+ *
+ * Handle writing the registers to the TLV320AIC310x
+ * series audio codecs, used on the BeagleBone Audio Cape.
+ * This code is designed to bypass the ALSA driver and
+ * configure the codec directly in a sensible way. It
+ * is complemented by code running on the PRU which uses
+ * the McASP serial port to transfer audio data.
+ *
