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>; | |
}; | |
}; |
