Kernel-4.18.0-80.el8_google,cros-ec-pw

• PWM controlled by ChromeOS EC

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).

Required properties:

• compatible: Must contain “google,cros-ec-pwm”
• #pwm-cells: Should be 1. The cell specifies the PWM index.

Example:
cros-ec@0 {
compatible = “google,cros-ec-spi”;

    ...

    cros_ec_pwm: ec-pwm {
        compatible = "google,cros-ec-pwm";
        #pwm-cells = <1>;
    };
};
