 * CS4245 and CS4361 both will mute all outputs if any clock ratio

 *
 * 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
