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 and DMA interrupts
7- clock-frequency: Desired I2C bus clock frequency in Hz.
8 Only 100000Hz and 400000Hz modes are supported.
9- fsl,i2c-dma-channel: APBX DMA channel for the I2C
