  * CMI8788:

  *   I²S 1 -> CS4245

  *   I²S 4 -> CS4361 (front)
+ *   Capture:

  *   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

  *   GPIO 8 -> enable output to speakers
  *
  * CS4245:

  *   input 2 <- front mic
- *   input 4 <- line/mic
+ *   input 4 <- line
  *   DAC out -> headphones
  *   aux out -> front panel headphones
