* Freescale MXS Inter IC (I2C) Controller
Required properties:
- compatible: Should be "fsl,<chip>-i2c"
- reg: Should contain registers location and length
- interrupts: Should contain ERROR interrupt number
- clock-frequency: Desired I2C bus clock frequency in Hz.
Only 100000Hz and 400000Hz modes are supported.
- dmas: DMA specifier, consisting of a phandle to DMA controller node
and I2C DMA channel ID.
Refer to dma.txt and fsl-mxs-dma.txt for details.
- dma-names: Must be "rx-tx".
Examples:
i2c0: i2c@80058000 {
#address-cells = <1>;
#size-cells = <0>;
compatible = "fsl,imx28-i2c";
reg = <0x80058000 2000>;
interrupts = <111>;
clock-frequency = <100000>;
dmas = <&dma_apbx 6>;
dma-names = "rx-tx";
};
