1STMicroelectronics STPMIC1 Onkey
2
3Required properties:
4
5- compatible = "st,stpmic1-onkey";
6- interrupts: interrupt line to use
7- interrupt-names = "onkey-falling", "onkey-rising"
8 onkey-falling: happens when onkey is pressed; IT_PONKEY_F of pmic
9 onkey-rising: happens when onkey is released; IT_PONKEY_R of pmic
10
11Optional properties:
12
13- st,onkey-clear-cc-flag: onkey is able power on after an
14 over-current shutdown event.
15- st,onkey-pu-inactive: onkey pull up is not active
16- power-off-time-sec: Duration in seconds which the key should be kept
17 pressed for device to power off automatically (from 1 to 16 seconds).
