ChangeLog v7->v8:
- The dts part of the patch that added the devicetree support for the imx35 was
moved here.
- The space in the nfc node was removed.
- A whitespace issue was fixed in imx35-pingrp.h
- fsl,ssi-dma-events was removed from the ssi node.
- The board specific iomuxc pins group configuration were removed.
ChangeLog v5->v6:
- The dependency on pdata clocks has been removed,
and the dtsi adapted accordinly.
- Adaptation to the for-next branch of Shawn Guo at
git://git.linaro.org/people/shawnguo/linux-2.6.git for-next
- imx35-dt.c: very small whitespace cleanup.
- Kconfig: The selection of IMX_HAVE_PLATFORM_* has been removed.
- dtsi: The nodes were reordered alphabetically.
- dtsi: The aliases have been reordered alphabetically.
- Shawn Guo was added in the Cc.
