+Nuvoton NPCM7XX I2C bus
+
+The NPCM750x includes sixteen I2C busses
+
+Required properties:
+- compatible : must be "nuvoton,npcm750-i2c-bus"
+- reg : Offset and length of the register set for the device.
+- interrupts : Contain the I2C interrupt with flags for falling edge.
+- clocks : phandle of I2C reference clock.
+
+Optional:
+- bus-frequency : Contain the I2C bus frequency,
+ the default I2C bus frequency is 100000.
+- pinctrl-0 : must be <&smbX_pins>, X is module number
+ (on NPCM7XX it's 0 to 15)
+- pinctrl-names : should be set to "default"
+Example:
+
+ i2c0: i2c-bus@80000 {
+ compatible = "nuvoton,npcm750-i2c-bus";
+ reg = <0x80000 0x1000>;
+ clocks = <&clk NPCM7XX_CLK_APB2>;
+ bus-frequency = <100000>;
+ interrupts = <GIC_SPI 64 IRQ_TYPE_LEVEL_HIGH>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&smb0_pins>;
+ };
