| NXP PCA9685 16-channel 12-bit PWM LED controller |
| ================================================ |
| |
| Required properties: |
| - compatible: "nxp,pca9685-pwm" |
| - #pwm-cells: Should be 2. See pwm.txt in this directory for a description of |
| the cells format. |
| The index 16 is the ALLCALL channel, that sets all PWM channels at the same |
| time. |
| |
| Optional properties: |
| - invert (bool): boolean to enable inverted logic |
| - open-drain (bool): boolean to configure outputs with open-drain structure; |
| if omitted use totem-pole structure |
| |
| Example: |
| |
| For LEDs that are directly connected to the PCA, the following setting is |
| applicable: |
| |
| pca: pca@41 { |
| compatible = "nxp,pca9685-pwm"; |
| #pwm-cells = <2>; |
| reg = <0x41>; |
| invert; |
| open-drain; |
| }; |
