1Generic GPIO bit-banged PWM driver 2 3Required properties: 4 - compatible: should be "pwm-gpio" 5 - #pwm-cells: should be 3, see pwm.txt in this directory for a general 6 description of the cells format. 7 - pwm-gpio: one gpio describing the used gpio, see the gpio bindings for the used gpio driver. 8 9Example: 10#include <dt-bindings/gpio/gpio.h> 11 12 pwm-gpio { 13 compatible = "pwm-gpio"; 14 #pwm-cells = <3>; 15 pwm-gpio = <&pio 7 1 GPIO_ACTIVE_HIGH>; 16 }; 17
