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";
};
