This patch adds support for the Analog Devices ADAU1361 and ADAU1761 CODECs. The device is a a low-power, 24-bit stereo audio CODEC with multiple analog input and outputs, one digital microphone input and an I2S interface. The device can be controlled either via I2C or SPI. The main difference between the two variants is that the ADAU1761 has a built-in SigmaDSP, while the ADAU1361 has not.
