/*
 * Definitions for Allo Piano DAC (2.0/2.1) boards
 *
 * NB. The Piano DAC 2.1 board contains 2x TI PCM5142 DAC's. One DAC is stereo
 * (left/right) and the other provides a subwoofer output, using DSP on the
 * chip for digital high/low pass crossover.
 * The initial support for this hardware, that doesn't require any codec driver
 * modifications, uses only one DAC chip for stereo (left/right) output, the
 * chip with 0x4c slave address. The other chip at 0x4d is currently ignored!
