A number of patches to impove or add the implementation
for the spi-imx driver related to Freescale IMX51, IMX53 and IMX6.
It would also possible some of patches can be applied for other
Freescale controllers using spi-imx driver but could not be tested
due to lack of hardware.

Changes since V3:
 Addressed comments from V3 review, simplified timeout calculation

Anton Bondarenko (7):
  spi: imx: Fix DMA transfer
  spi: imx: replace fixed timeout with calculated one
  spi: imx: add support for all SPI word width for DMA transfer
  spi: imx: add function to check for IMX51 family controller
  spi: imx: Add support for loopback for ECSPI controllers
  spi: imx: return error from dma channel request
  spi: imx: defer spi initialization, if DMA engine is pending
