| 7 | * This driver was based on the work of Greg Wickham and Adrian |
| 8 | * Dewhurst. It was substantially rewritten to support correct signal |
| 9 | * gaps and now maintains a delay buffer, which is used to present |
| 10 | * consistent timing behaviour to user space applications. Without the |
| 11 | * delay buffer an ugly hack would be required in lircd, which can |
| 12 | * cause sluggish signal decoding in certain situations. |
