1* Synopsys DesignWare I2C
2
3Required 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
9Recommended properties :
10
11 - clock-frequency : desired I2C bus clock frequency in Hz.
12
13Optional 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.

17Example :
18
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 };
27
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>;
37 };
