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
doc/device-tree-bindings/misc/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>;
};
};
