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.

/*
* Currently tested and works on:
* Lenovo IdeaPad Y550
* Lenovo IdeaPad Y550P
*
* Other models can be added easily. To test,
* load with 'force' parameter set 'true'.
*
* LEDs blinking and input mode are managed via sysfs,
* (hex, unsigned byte value):
* /sys/devices/platform/ideapad_slidebar/slidebar_mode
*
* The value is in byte range, however, I only figured out

*
* Possible states:
*
* STD_INT, ONMOV_INT, OFF_INT, LAST_POLL, OFF_POLL
*
* Meaning:
* released touched
* STD 'heartbeat' lights follow the finger
* ONMOV no lights lights follow the finger
* LAST at last pos lights follow the finger
* OFF no lights no lights
*
* INT all input events are generated, interrupts are used
* POLL no input events by default, to get them,
* send 0b10000000 (read below)
*
* Commands: write
