2 * Marvell MV64XXX I2C controller
3
4 Required 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
19 Optional properties :
20
21  - clock-frequency : Desired I2C bus clock frequency in Hz. If not set the
22 default 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.
27
28  - clocks:         : pointers to the reference clocks for this device, the
29                      first one is the one used for the clock on the i2c bus,
30                      the second one is the clock used to acces the registers
31                      of the controller
32
33  - clock-names     : names of used clocks, mandatory if the second clock is
34                      used, the name must be "core", and "reg" (the latter is
35                      only for Armada 7K/8K).

37 Examples:
38
39         i2c@11000 {
40                 compatible = "marvell,mv64xxx-i2c";
41                 reg = <0x11000 0x20>;
42                 interrupts = <29>;
43                 clock-frequency = <100000>;
44         };
45
46 For the Armada XP:
47
48         i2c@11000 {
49                 compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c";
50                 reg = <0x11000 0x100>;
51                 interrupts = <29>;
52                 clock-frequency = <100000>;
53         };
54
55 For the Armada 7040:
56
57         i2c@701000 {
58                 compatible = "marvell,mv78230-i2c";
59                 reg = <0x701000 0x20>;
60                 interrupts = <29>;
61                 clock-frequency = <100000>;
62                 clock-names = "core", "reg";
63                 clocks = <&core_clock>, <&reg_clock>;
64         };
