1* Freescale MXS Inter IC (I2C) Controller 2 3Required properties: 4- compatible: Should be "fsl,<chip>-i2c" 5- reg: Should contain registers location and length 6- interrupts: Should contain ERROR interrupt number 7- clock-frequency: Desired I2C bus clock frequency in Hz. 8 Only 100000Hz and 400000Hz modes are supported. 9- dmas: DMA specifier, consisting of a phandle to DMA controller node 10 and I2C DMA channel ID. 11 Refer to dma.txt and fsl-mxs-dma.txt for details. 12- dma-names: Must be "rx-tx". 13 14Examples: 15 16i2c0: i2c@80058000 { 17 #address-cells = <1>; 18 #size-cells = <0>; 19 compatible = "fsl,imx28-i2c"; 20 reg = <0x80058000 2000>; 21 interrupts = <111>; 22 clock-frequency = <100000>; 23 dmas = <&dma_apbx 6>; 24 dma-names = "rx-tx"; 25}; 26
