 668 * The mc13783 has two SSI ports, both of them can be routed either
 669 * to the voice codec or the stereo DAC. When two different SSI ports
 670 * are used for the voice codec and the stereo DAC we can do different
 671 * formats and sysclock settings for playback and capture
 672 * (mc13783-hifi-playback and mc13783-hifi-capture). Using the same port
 673 * forces us to use symmetric rates (mc13783-hifi).
