allows monitoring of temperature sensors and fans attached to the
EC.

+Chromium Embedded Controller EC temperature and fan control
+-----------------------------------------------------------
+
+Google's Chromium EC HWMON is a hwmon implemented byimplemented by the Chromium EC
+firmware attached to the Embedded Controller (EC) and controlled via a host-command
+interface.
+
+An EC HWMON 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-hwmon"
+
+Example:
+	embedded-controller@1e {
+		reg = <0x1e>;
+		compatible = "google,cros-ec-i2c";
+		interrupts = <0 IRQ_TYPE_LEVEL_LOW>;
+		interrupt-parent = <&gpio0>;
+
+		hwmon {
+			compatible = "google,cros-ec-hwmon";
+		};
+};
