+ * Xonar DG/DGX
+ * ------------
+ *
+ * CS4245 and CS4361 both will mute all outputs if any clock ratio
+ * is invalid.
+ *
+ * CMI8788:
+ *
+ *   SPI 0 -> CS4245
+ *
+ *   Playback:
+ *   I²S 1 -> CS4245
+ *   I²S 2 -> CS4361 (center/LFE)
+ *   I²S 3 -> CS4361 (surround)
+ *   I²S 4 -> CS4361 (front)
+ *   Capture:
+ *   I²S ADC 1 <- CS4245
+ *
+ *   GPIO 3 <- ?
+ *   GPIO 4 <- headphone detect
+ *   GPIO 5 -> enable ADC analog circuit for the left channel
+ *   GPIO 6 -> enable ADC analog circuit for the right channel
+ *   GPIO 7 -> switch green rear output jack between CS4245 and and the first
+ *             channel of CS4361 (mechanical relay)
+ *   GPIO 8 -> enable output to speakers
+ *
+ * CS4245:
+ *
+ *   input 0 <- mic
+ *   input 1 <- aux
+ *   input 2 <- front mic
+ *   input 4 <- line
+ *   DAC out -> headphones
+ *   aux out -> front panel headphones
