+Netronix Embedded Controller
+
+This EC is found in e-book readers of multiple brands (e.g. Kobo, Tolino), and
+is typically implemented as a TI MSP430 microcontroller.
+
+
+Required properties:
+- compatible: should be "netronix,ntxec"
+- reg: The I2C address of the EC
+
+Optional properties:
+- system-power-controller:
+  See Documentation/devicetree/bindings/power/power-controller.txt
+- interrupts or interrupts-extended
+- interrupt-controller
+- #interrupt-cells: Should be 1
+
+Optional subnodes:
+
+Sub-nodes are identified by their compatible string.
+
+ compatible string              | description
+--------------------------------|--------------------------------------
+ netronix,ntxec-pwm             | PWM (used for backlight)
+ netronix,ntxec-rtc             | real time clock
+
+
+Example:
+
+&i2c3 {
+	pinctrl-names = "default";
+	pinctrl-0 = <&pinctrl_i2c3>;
+	status = "okay";
+
+	ec: embedded-controller@43 {

+		pwm {

+			interrupts-extended = <&ec 15>;
+			interrupt-names = "alarm";
