+Nuvoton NPCM USB Device controller.
+
+This DT-binding describe Nuvoton NPCM USB Device controller (UDC) device node.
+The UDC is based on Chipidea Subsystem Device Controller IP.
+
+Required properties:
+- compatible : "nuvoton,npcm750-udc" for Poleg NPCM7XX.
+ "nuvoton,npcm845-udc" for Arbel NPCM8XX.
+- reg : Offset and length of the register set for the device,
+ Offset and length of the DTD buffer.
+- interrupts : Contain the UDC interrupt.
+- clocks : phandle of UDC reference clock.
+- clock-names : Should be "clk_usb_bridge".
+
+Note: Each npcm-udc which should have an alias correctly numbered
+in "aliases" node.
+
+e.g.
+aliases {
+ udc1 = &udc1;
+};
+
+Example:
+ udc0:udc@f0830000 {
+ compatible = "nuvoton,npcm750-udc";
+ reg = <0xf0830000 0x1000
+ 0xfffd0000 0x800>;
+ interrupts = <GIC_SPI 51 IRQ_TYPE_LEVEL_HIGH>;
+ status = "disabled";
+ clocks = <&clk NPCM7XX_CLK_SU>;
+ clock-names = "clk_usb_bridge";
+ };
+
