-* 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";
-};
