+Broadcom BCM2835 I2C controller
+
+Required properties:
+- compatible : Should be one of:
+	"brcm,bcm2711-i2c"
+	"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@7e205000 {
+	compatible = "brcm,bcm2835-i2c";
+	reg = <0x7e205000 0x1000>;
+	interrupts = <2 21>;
+	clocks = <&clk_i2c>;
+	clock-frequency = <100000>;
+};
