+arcxcnn bindings
+
+Required properties:
+  - compatible: "arc,arcxcnn", "arc,arc2c0608"
+  - reg: I2C slave address (u8)
+
+Optional properties:
+  - bl-name: Backlight device name (string)
+  - init-brt: Initial value of backlight brightness (u32) low 16 bits used
+  - pwm-period: PWM period value. Set only PWM input mode used (u32)
+  - prg-addr: Register address of ROM area to be updated (u32) low 8 bits used
+  - prg-val: Register value to be updated (u32) low 8 bits used
+
+Example:
+
+	/* ARC2C0608 */
+	backlight@30 {
+		compatible = "arc,arc2c0608";
+		reg = <0x30>;
+
+		init-brt = <123>;
+
+		/* LED0+1 string enabled */
+		prg_06h {
+			prg-addr = <0x06>;
+			prg-val = <0x83>;
+		};
+
+	};
