* 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>;
|
|
};
|
|
};
