+Broadcom Kona Family I2C
+=========================
+
+This I2C controller is used in the following Broadcom SoCs:
+
+ BCM11130
+ BCM11140
+ BCM11351
+ BCM28145
+ BCM28155
+
+Required Properties
+-------------------
+- compatible: "brcm,bcm11351-i2c", "brcm,kona-i2c"
+- reg: Physical base address and length of controller registers
+- interrupts: The interrupt number used by the controller
+- clocks: clock specifier for the kona i2c external clock
+- clock-frequency: The I2C bus frequency in Hz
+- #address-cells: Should be <1>
+- #size-cells: Should be <0>
+
+Refer to clocks/clock-bindings.txt for generic clock consumer
+properties.
+
+Example:
+
+i2c@3e016000 {
+ compatible = "brcm,bcm11351-i2c","brcm,kona-i2c";
+ reg = <0x3e016000 0x80>;
+ interrupts = <GIC_SPI 103 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&bsc1_clk>;
+ clock-frequency = <400000>;
+ #address-cells = <1>;
+ #size-cells = <0>;
+};
