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 compatible = "pps-gpio"; 17 gpios = <&gpio2 6 0>; 18 19 assert-falling-edge; 20 }; 21
