Jarod Wilson | 66e8952 | 2010-06-01 17:32:08 -0300 | [diff] [blame] | 5 | * |
| 6 | * Based on the original lirc_mceusb and lirc_mceusb2 drivers, by Dan |
| 7 | * Conti, Martin Blatter and Daniel Melander, the latter of which was |
| 8 | * in turn also based on the lirc_atiusb driver by Paul Miller. The |
| 9 | * two mce drivers were merged into one by Jarod Wilson, with transmit |
| 10 | * support for the 1st-gen device added primarily by Patrick Calhoun, |
| 11 | * with a bit of tweaks by Jarod. Debugging improvements and proper |
| 12 | * support for what appears to be 3rd-gen hardware added by Jarod. |
| 13 | * Initial port from lirc driver to ir-core drivery by Jarod, based |
| 14 | * partially on a port to an earlier proposed IR infrastructure by |
| 15 | * Jon Smirl, which included enhancements and simplifications to the |
| 16 | * incoming IR buffer parsing routines. |
| 17 | * |

| 19 | * remote/transceiver requirements and specification document, found at |
