+Atmel PWM controller
+
+Required properties:
+  - compatible: should be one of:
+    - "atmel,at91sam9rl-pwm"
+    - "atmel,sama5d3-pwm"
+  - reg: physical base address and length of the controller's registers
+  - #pwm-cells: Should be 3. See pwm.txt in this directory for a
+    description of the cells format.
+
+Example:
+
+	pwm0: pwm@f8034000 {
+		compatible = "atmel,at91sam9rl-pwm";
+		reg = <0xf8034000 0x400>;
+		#pwm-cells = <3>;
+	};
+
+	pwmleds {
+		compatible = "pwm-leds";
+
+		d1 {
+			label = "d1";
+			pwms = <&pwm0 3 5000 0>
+			max-brightness = <255>;
+		};
+
+		d2 {
+			label = "d2";
+			pwms = <&pwm0 1 5000 1>
+			max-brightness = <255>;
+		};
+	};

+Marvell PWM controller
+
+Required properties:
+- compatible: should be one or more of:
+  - "marvell,pxa250-pwm"
+  - "marvell,pxa270-pwm"
+  - "marvell,pxa168-pwm"
+  - "marvell,pxa910-pwm"
+- reg: Physical base address and length of the registers used by the PWM channel
+  Note that one device instance must be created for each PWM that is used, so the
+  length covers only the register window for one PWM output, not that of the
+  entire PWM controller.  Currently length is 0x10 for all supported devices.
+- #pwm-cells: Should be 1.  This cell is used to specify the period in
+  nanoseconds.
+
+Example PWM device node:
+
+pwm0: pwm@40b00000 {
+	compatible = "marvell,pxa250-pwm";
+	reg = <0x40b00000 0x10>;
+	#pwm-cells = <1>;
+};
+
+Example PWM client node:
+
+backlight {
+	compatible = "pwm-backlight";
+	pwms = <&pwm0 5000000>;
+	...
+}
