1NXP PCA9685 16-channel 12-bit PWM LED controller 2================================================ 3 4Required properties: 5 - compatible: "nxp,pca9685-pwm" 6 - #pwm-cells: Should be 2. See pwm.yaml in this directory for a description of 7 the cells format. 8 The index 16 is the ALLCALL channel, that sets all PWM channels at the same 9 time. 10 11Optional properties: 12 - invert (bool): boolean to enable inverted logic 13 - open-drain (bool): boolean to configure outputs with open-drain structure; 14 if omitted use totem-pole structure 15 16Example: 17 18For LEDs that are directly connected to the PCA, the following setting is 19applicable: 20 21pca: pca@41 { 22 compatible = "nxp,pca9685-pwm"; 23 #pwm-cells = <2>; 24 reg = <0x41>; 25 invert; 26 open-drain; 27};
