|
|
* ------------
|
|
*
|
|
* 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 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
