+ * Currently tested and works on:

+ *
+ * LEDs blinking and input mode are managed via sysfs,

+ * /sys/devices/platform/ideapad_slidebar/slidebar_mode
+ *
+ * The value is in byte range, however, I only figured out

+ * Possible states:

+ *
+ * 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
