description: |
  Google's ChromeOS EC PWM is a simple PWM attached to the Embedded Controller
  (EC) and controlled via a host-command interface.
  An EC PWM node should be only found as a sub-node of the EC node (see
  Documentation/devicetree/bindings/mfd/cros-ec.txt).

properties:
  compatible:
    const: google,cros-ec-pwm
  "#pwm-cells":
    description: The cell specifies the PWM index.
    const: 1

required:
  - compatible
  - '#pwm-cells'

additionalProperties: false

    spi {
        #address-cells = <1>;
        #size-cells = <0>;
