1Actions Semiconductor Owl I2C controller
2
3Required properties:
4
5- compatible        : Should be one of the following:
6		      - "actions,s700-i2c" for S700 SoC
7		      - "actions,s900-i2c" for S900 SoC
8- reg               : Offset and length of the register set for the device.
9- #address-cells    : Should be 1.
10- #size-cells       : Should be 0.
11- interrupts        : A single interrupt specifier.
12- clocks            : Phandle of the clock feeding the I2C controller.
13
14Optional properties:
15
16- clock-frequency   : Desired I2C bus clock frequency in Hz. As only Normal and
17                      Fast modes are supported, possible values are 100000 and
18                      400000.
19Examples:

21        i2c0: i2c@e0170000 {
22                compatible = "actions,s900-i2c";
23                reg = <0 0xe0170000 0 0x1000>;
24                #address-cells = <1>;
25                #size-cells = <0>;
26                interrupts = <GIC_SPI 25 IRQ_TYPE_LEVEL_HIGH>;
27                clocks = <&clock CLK_I2C0>;
28                clock-frequency = <100000>;
29        };
