+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>;
+ };
+ };
