8 | The index 16 is the ALLCALL channel, that sets all PWM channels at the same |
9 | time. | |
10 | ||
11 | Optional 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 | |

16 | Example: | |
17 | ||
18 | For LEDs that are directly connected to the PCA, the following setting is | |
19 | applicable: | |
20 | ||
21 | pca: pca@41 { | |
22 | compatible = "nxp,pca9685-pwm"; | |
23 | #pwm-cells = <2>; | |
24 | reg = <0x41>; | |
25 | invert; | |
26 | open-drain; | |
