1	* Synopsys DesignWare I2C
2	
3	Required properties :
4	
5	 - compatible : should be "snps,designware-i2c"
6	 - reg : Offset and length of the register set for the device
7	 - interrupts : <IRQ> where IRQ is the interrupt number.
8	
9	Recommended properties :
10	
11	 - clock-frequency : desired I2C bus clock frequency in Hz.
12	
13	Optional properties :
14	 - i2c-sda-hold-time-ns : should contain the SDA hold time in nanoseconds.
15	   This option is only supported in hardware blocks version 1.11a or newer.
16	
17	Example :

19		i2c@f0000 {
20			#address-cells = <1>;
21			#size-cells = <0>;
22			compatible = "snps,designware-i2c";
23			reg = <0xf0000 0x1000>;
24			interrupts = <11>;
25			clock-frequency = <400000>;
26		};

28		i2c@1120000 {
29			#address-cells = <1>;
30			#size-cells = <0>;
31			compatible = "snps,designware-i2c";
32			reg = <0x1120000 0x1000>;
33			interrupt-parent = <&ictl>;
34			interrupts = <12 1>;
35			clock-frequency = <400000>;
36			i2c-sda-hold-time-ns = <300>;
