2* Marvell MV64XXX I2C controller
3
4Required properties :
5
6 - reg             : Offset and length of the register set for the device
7 - compatible      : Should be either:
8                     - "allwinner,sun4i-a10-i2c"
9                     - "allwinner,sun6i-a31-i2c"
10                     - "marvell,mv64xxx-i2c"
11                     - "marvell,mv78230-i2c"
12                     - "marvell,mv78230-a0-i2c"
13                       * Note: Only use "marvell,mv78230-a0-i2c" for a
14                         very rare, initial version of the SoC which
15                         had broken offload support.  Linux
16                         auto-detects this and sets it appropriately.
17 - interrupts      : The interrupt number
18
19Optional properties :
20
21 - clock-frequency : Desired I2C bus clock frequency in Hz. If not set the
22default frequency is 100kHz
23
24 - resets          : phandle to the parent reset controller. Mandatory
25                     whenever you're using the "allwinner,sun6i-a31-i2c"
26                     compatible.

28Examples:
29
30	i2c@11000 {
31		compatible = "marvell,mv64xxx-i2c";
32		reg = <0x11000 0x20>;
33		interrupts = <29>;
34		clock-frequency = <100000>;
35	};
36
37For the Armada XP:
38
39	i2c@11000 {
40		compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c";
41		reg = <0x11000 0x100>;
42		interrupts = <29>;
43		clock-frequency = <100000>;
44	};
