1Device-Tree Bindings for a PPS Signal on GPIO
2
3These properties describe a PPS (pulse-per-second) signal connected to
4a GPIO pin.
5
6Required properties:
7- compatible: should be "pps-gpio"
8- gpios: one PPS GPIO in the format described by ../gpio/gpio.txt
9
10Optional properties:
11- assert-falling-edge: when present, assert is indicated by a falling edge
12                       (instead of by a rising edge)
13
14Example:
15	pps {
16		pinctrl-names = "default";
17		pinctrl-0 = <&pinctrl_pps>;
18
19		gpios = <&gpio1 26 GPIO_ACTIVE_HIGH>;
20		assert-falling-edge;
21
22		compatible = "pps-gpio";
23	};
