Merge tag 'davinci-for-v3.11/soc-v2' of... 

Merge tag 'davinci-for-v3.11/soc-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/soc

From Sekhar Nori:

DaVinci SoC changes for v3.11

This pull request moves DaVinci EDMA library to
arch/arm/common so it can be used by OMAP based AM335x.
This is a temporary step until all drivers are converted
to use the dmaengine driver in drivers/dma/edma.c.

Several drivers like SPI, MMC/SD have already been converted.
Some like audio are pending.

The other two patches in the pull request are cleanup in nature.

* tag 'davinci-for-v3.11/soc-v2' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
  ARM: edma: remove unused transfer controller handlers
  ARM: davinci: move private EDMA API to arm/common
  ARM: davinci: remove __init atrribute from function declaration
