+Broadcom BCM2835 I2C controller
+
+Required properties:
+- compatible : Should be "brcm,bcm2835-i2c".
+- reg: Should contain register location and length.
+- interrupts: Should contain interrupt.
+- clocks : The clock feeding the I2C controller.
+
+Recommended properties:
+- clock-frequency : desired I2C bus clock frequency in Hz.
+
+Example:
+
+i2c@20205000 {
+ compatible = "brcm,bcm2835-i2c";
+ reg = <0x7e205000 0x1000>;
+ interrupts = <2 21>;
+ clocks = <&clk_i2c>;
+ clock-frequency = <100000>;
+};
