2 * Marvell MV64XXX I2C controller
4 Required properties :
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
19 Optional properties :
21  - clock-frequency : Desired I2C bus clock frequency in Hz. If not set the
22 default frequency is 100kHz
24  - resets          : phandle to the parent reset controller. Mandatory
25                      whenever you're using the "allwinner,sun6i-a31-i2c"
26                      compatible.
28 Examples:
30         i2c@11000 {
31                 compatible = "marvell,mv64xxx-i2c";
32                 reg = <0x11000 0x20>;
33                 interrupts = <29>;
34                 clock-frequency = <100000>;
35         };
37 For the Armada XP:
39         i2c@11000 {
40                 compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c";
41                 reg = <0x11000 0x100>;
42                 interrupts = <29>;
43                 clock-frequency = <100000>;
44         };
