title: NXP PCA963x LED controllers

maintainers:
  - Laurent Pinchart <laurent.pinchart@ideasonboard.com>

description: |
  The NXP PCA963x are I2C-controlled LED drivers optimized for
  Red/Green/Blue/Amber (RGBA) color mixing applications. Each LED is
  individually controllable and has its own PWM controller.

  nxp,hw-blink:
    type: boolean
    description:
      Use hardware blinking instead of software blinking

  nxp,inverted-out:
    type: boolean
    description:
      Invert the polarity of the generated PWM.

  nxp,period-scale:
    $ref: /schemas/types.yaml#/definitions/uint32
    description:
      In some configurations, the chip blinks faster than expected. This
      parameter provides a scaling ratio (fixed point, decimal divided by 1000)
      to compensate, e.g. 1300=1.3x and 750=0.75x.

  nxp,totem-pole:
    type: boolean
    description:
      Use totem pole (push-pull) instead of open-drain (pca9632 defaults to
      open-drain, newer chips to totem pole).
