| 2 | * Apple Onboard Audio driver for Onyx codec |
| 3 | * |
| 4 | * Copyright 2006 Johannes Berg <johannes@sipsolutions.net> |
| 5 | * |
| 6 | * GPL v2, can be found in COPYING. |
| 7 | * |
| 8 | * |
| 9 | * This is a driver for the pcm3052 codec chip (codenamed Onyx) |
| 10 | * that is present in newer Apple hardware (with digital output). |
| 11 | * |
| 12 | * The Onyx codec has the following connections (listed by the bit |
| 13 | * to be used in aoa_codec.connected): |
| 14 | * 0: analog output |
| 15 | * 1: digital output |
| 16 | * 2: line input |
| 17 | * 3: microphone input |
| 18 | * Note that even though I know of no machine that has for example |
| 19 | * the digital output connected but not the analog, I have handled |
| 20 | * all the different cases in the code so that this driver may serve |
| 21 | * as a good example of what to do. |
| 22 | * |
| 23 | * NOTE: This driver assumes that there's at most one chip to be |
| 24 | * used with one alsa card, in form of creating all kinds |
| 25 | * of mixer elements without regard for their existence. |
| 26 | * But snd-aoa assumes that there's at most one card, so |
| 27 | * this means you can only have one onyx on a system. This |
| 28 | * should probably be fixed by changing the assumption of |
| 29 | * having just a single card on a system, and making the |
| 30 | * 'card' pointer accessible to anyone who needs it instead |
| 31 | * of hiding it in the aoa_snd_* functions... |
| 32 | * |
