From: Joerg Schambacher joerg@hifiberry.com

Adds a minimum component driver to run the amplifier in I2S master mode only from standard audio clocks. Therefore, it only allows 44.1, 88.2, 176.4, 48, 96 and 192ksps with 16, 20, 24 and 32 bits sample size. Digital volume control and the -6dB switch are supported.
