| Input: sysrq reset sequence | |
| A simple binding to represent a set of keys as described in | |
| include/uapi/linux/input.h. This is to communicate a sequence of keys to the | |
| sysrq driver. Upon holding the keys for a specified amount of time (if | |
| specified) the system is sync'ed and reset. | |
| Key sequences are global to the system but all the keys in a set must be coming | |
| from the same input device. | |
| The /chosen node should contain a 'linux,sysrq-reset-seq' child node to define | |
| a set of keys. | |
| Required property: | |
| sysrq-reset-seq: array of Linux keycodes, one keycode per cell. | |
| Optional property: | |
| timeout-ms: duration keys must be pressed together in milliseconds before | |
| generating a sysrq. If omitted the system is rebooted immediately when a valid | |
| sequence has been recognized. | |
| Example: | |
| chosen { | |
| linux,sysrq-reset-seq { | |
| keyset = <0x03 | |
| 0x04 | |
| 0x0a>; | |
| timeout-ms = <3000>; | |
| }; | |
| }; | |
| Would represent KEY_2, KEY_3 and KEY_9. |
