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.
