Cadence I2C controller Device Tree Bindings
-------------------------------------------

Required properties:
- compatible		: Should be "cdns,i2c-r1p10" or "xlnx,zynq-spi-r1p10".
- reg			: Physical base address and size of I2C registers map.
- interrupts		: Property with a value describing the interrupt
			  number.
- interrupt-parent	: Must be core interrupt controller
- clocks		: Clock phandles (see clock bindings for details).

Optional properties:
- fifo-depth		: To specify the FIFO depth of the controller.

Example:
	i2c0: i2c@e0004000 {
		compatible = "cdns,i2c-r1p10";
		reg = <0xe0004000 0x1000>;
		clocks = <&clkc 38>;
		interrupts = <0 25 4>;
		interrupt-parent = <&intc>;
		fifo-depth = <32>;
		status = "disabled";
	};
