1* Altera I2C Controller
2* This is Altera's synthesizable logic block I2C Controller for use
3* in Altera's FPGAs.

5Required properties :
6 - compatible : should be "altr,softip-i2c-v1.0"
7 - reg        : Offset and length of the register set for the device
8 - interrupts : <IRQ> where IRQ is the interrupt number.
9 - clocks     : phandle to input clock.
10 - #address-cells = <1>;
11 - #size-cells = <0>;
12
13Recommended properties :
14 - clock-frequency : desired I2C bus clock frequency in Hz.
15
16Optional properties :
17 - fifo-size : Size of the RX and TX FIFOs in bytes.
18 - Child nodes conforming to i2c bus binding

25		interrupt-parent = <&intc>;
26		interrupts = <0 43 4>;
27		clocks = <&clk_0>;
28		clock-frequency = <100000>;
29		#address-cells = <1>;
30		#size-cells = <0>;
31		fifo-size = <4>;
