Dove Audio 0: - I2S in - I2S out - No SPDIF Dove Audio 1: - I2S in - I2S out - SPDIF out only Both these variants occur on the same SoC. Kirkwood: - I2S in - SPDIF in - I2S out - SPDIF out Preconditions: 1. Only one input can be used at any one time. 2. One output can be used or both if enabled simultaneously. -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
