 * 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
