+Broadcom iProc I2C controller
+
+Required properties:
+
+- compatible:
+    Must be "brcm,iproc-i2c"
+
+- reg:
+    Define the base and range of the I/O address space that contain the iProc
+    I2C controller registers
+
+- interrupts:
+    Should contain the I2C interrupt
+
+- clock-frequency:
+    This is the I2C bus clock. Need to be either 100000 or 400000
+
+- #address-cells:
+    Always 1 (for I2C addresses)
+
+- #size-cells:
+    Always 0
+
+Example:
+	i2c0: i2c@18008000 {
+		compatible = "brcm,iproc-i2c";
+		reg = <0x18008000 0x100>;
+		#address-cells = <1>;
+		#size-cells = <0>;
+		interrupts = <GIC_SPI 85 IRQ_TYPE_NONE>;
+		clock-frequency = <100000>;
+
+		codec: wm8750@1a {
+			compatible = "wlf,wm8750";
+			reg = <0x1a>;
+		};
+	};
