| 33 | * Acer Labs M5455 audio driver |
| 34 | * |
| 35 | * Acer provides data sheets after signing an NDA, so this is guess work. |
| 36 | * The chip behaves somewhat like the Intel i8x0, so this driver |
| 37 | * is loosely based on the auich driver. Additional information taken from |
| 38 | * the ALSA intel8x0.c driver (which handles M5455 as well). |
| 39 | * |
| 40 | * As an historical note one can observe that the auich driver borrows |
| 41 | * lot from the first NetBSD PCI audio driver, the eap driver. But this |
| 42 | * is not attributed anywhere. |
