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