1Input: sysrq reset sequence2 3A simple binding to represent a set of keys as described in4include/uapi/linux/input.h. This is to communicate a sequence of keys to the5sysrq driver. Upon holding the keys for a specified amount of time (if6specified) the system is sync'ed and reset.7 8Key sequences are global to the system but all the keys in a set must be coming9from the same input device.10 11The /chosen node should contain a 'linux,sysrq-reset-seq' child node to define12a set of keys.13 14Required property:15keyset: array of Linux keycodes, one keycode per cell.16 17Optional property:18timeout-ms: duration keys must be pressed together in milliseconds before19generating a sysrq. If omitted the system is rebooted immediately when a valid20sequence has been recognized.21 22Example:23 24 chosen {25 linux,sysrq-reset-seq {26 keyset = <0x0327 0x0428 0x0a>;29 timeout-ms = <3000>;30 };31 };32 33Would represent KEY_2, KEY_3 and KEY_9.34
