3*c66ec88fSEmmanuel Vadot
4*c66ec88fSEmmanuel VadotRequired properties:
5*c66ec88fSEmmanuel Vadot  - compatible: "nxp,pca9685-pwm"
6*c66ec88fSEmmanuel Vadot  - #pwm-cells: Should be 2. See pwm.yaml in this directory for a description of
7*c66ec88fSEmmanuel Vadot    the cells format.
8*c66ec88fSEmmanuel Vadot    The index 16 is the ALLCALL channel, that sets all PWM channels at the same
9*c66ec88fSEmmanuel Vadot    time.
10*c66ec88fSEmmanuel Vadot
11*c66ec88fSEmmanuel VadotOptional properties:
12*c66ec88fSEmmanuel Vadot  - invert (bool): boolean to enable inverted logic
13*c66ec88fSEmmanuel Vadot  - open-drain (bool): boolean to configure outputs with open-drain structure;
14*c66ec88fSEmmanuel Vadot		       if omitted use totem-pole structure
