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: |
|
keyset: 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.
