Nuvoton NPCM7XX I2C Controller
NPCM7xx includes 16 I2C contollers. This driver operates the controller.
This module also includes a slave mode, which will be submitted later on.

Any feedback would be appreciated.

+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>;
+	};
