The AMP4 Pro is a I2S master mode capable amplifier with clean onboard clock generators. We can share the card driver between TAS575x amplifiers and the PCM512x DACs as they are SW compatible. From a HW perspective though we need to limit the sample rates to the standard audio rates to avoid running the onboard clocks through the PLL. Using the PLL would require even a different HW. DAI/stream name are also set accordingly to allow the user a convenient identification of the soundcard Needs the pcm512x driver with TAS575x support (already in upstream kernel).

The AMP4 Pro uses a TI TAS5756 amplifier in master mode and requires the DAC Plus card driver and the pcm512x component driver with TAS support. Signed-off-by: Joerg Schambacher <[email protected]>
