* Marvell MV64XXX I2C controller
Required properties :
- reg : Offset and length of the register set for the device
- compatible : Should be either:
- "allwinner,sun4i-i2c"
- "allwinner,sun6i-a31-i2c"
- "marvell,mv64xxx-i2c"
- "marvell,mv78230-i2c"
- "marvell,mv78230-a0-i2c"
* Note: Only use "marvell,mv78230-a0-i2c" for a
very rare, initial version of the SoC which
had broken offload support. Linux
auto-detects this and sets it appropriately.
- interrupts : The interrupt number
Optional properties :
- clock-frequency : Desired I2C bus clock frequency in Hz. If not set the
default frequency is 100kHz
- resets : phandle to the parent reset controller. Mandatory
whenever you're using the "allwinner,sun6i-a31-i2c"
compatible.
Examples:
i2c@11000 {
compatible = "marvell,mv64xxx-i2c";
reg = <0x11000 0x20>;
interrupts = <29>;
clock-frequency = <100000>;
};
For the Armada XP:
i2c@11000 {
compatible = "marvell,mv78230-i2c", "marvell,mv64xxx-i2c";
reg = <0x11000 0x100>;
interrupts = <29>;
clock-frequency = <100000>;
};
