* 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 -> route input jack to line-in (0) or mic-in (1)
* GPIO 6 -> route input jack to line-in (0) or mic-in (1)
* GPIO 7 -> enable rear headphone amp
* 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/mic
* input 4 <- line
* DAC out -> headphones
* aux out -> front panel headphones
