* SiRF atlas6 and prima2 internal audio codec and port based audio setups
Required properties:
- compatible: "sirf,sirf-audio-card"
- sirf,audio-platform: phandle for the platform node
- sirf,audio-codec: phandle for the SiRF internal codec node
Optional properties:
- hp-pa-gpios: Need to be present if the board need control external
headphone amplifier.
