1 Input: sysrq reset sequence
3 A simple binding to represent a set of keys as described in
4 include/uapi/linux/input.h. This is to communicate a sequence of keys to the
5 sysrq driver. Upon holding the keys for a specified amount of time (if
6 specified) the system is sync'ed and reset.
8 Key sequences are global to the system but all the keys in a set must be coming
9 from the same input device.
11 The /chosen node should contain a 'linux,sysrq-reset-seq' child node to define
15 sysrq-reset-seq: array of Linux keycodes, one keycode per cell.
18 timeout-ms: duration keys must be pressed together in milliseconds before
19 generating a sysrq. If omitted the system is rebooted immediately when a valid
20 sequence has been recognized.
25 linux,sysrq-reset-seq {
33 Would represent KEY_2, KEY_3 and KEY_9.
