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>;

};
