2013-04-04i2c: i2c-mxs: move to use generic DMA helperShawn Guo
With the generic DMA device tree helper supported by mxs-dma driver, client devices only need to call dma_request_slave_channel() for requesting a DMA channel from dmaengine.

2012-10-08MXS: Implement DMA support into mxs-i2cMarek Vasut
This patch implements DMA support into mxs-i2c. DMA transfers are now enabled via DT. The DMA operation is enabled by default.

2012-07-13i2c: mxs: Set I2C timing registers for mxs-i2cMarek Vasut
This patch configures the I2C bus timing registers according to information passed via DT. Currently, 100kHz and 400kHz modes are supported. The TIMING2 register value is wrong in the documentation for i.MX28!
