| 13 | * Notes: |
| 14 | * The AIC3X is a driver for a low power stereo audio |
| 15 | * codecs aic31, aic32, aic33. |
| 16 | * |
| 17 | * It supports full aic33 codec functionality. |
| 18 | * The compatibility with aic32, aic31 is as follows: |
| 19 | * aic32 | aic31 |
| 20 | * --------------------------------------- |
| 21 | * MONO_LOUT -> N/A | MONO_LOUT -> N/A |
| 22 | * | IN1L -> LINE1L |
| 23 | * | IN1R -> LINE1R |
| 24 | * | IN2L -> LINE2L |
| 25 | * | IN2R -> LINE2R |
| 26 | * | MIC3L/R -> N/A |
| 27 | * truncated internal functionality in |
| 28 | * accordance with documentation |
| 29 | * --------------------------------------- |
| 30 | * |
| 31 | * Hence the machine layer should disable unsupported inputs/outputs by |
