Merge tag 'ux500-fixes-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson into fixes

From Linus Walleij <linus.walleij@stericsson.com>:

Fixes boot regressions on Device Tree:
- Get TCPM and TCDM locations from the device tree
- Skip passing the ios_handler for the MMCI
- Enable the ethernet clock for Snowball

* tag 'ux500-fixes-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-stericsson:
  ARM: ux500: Enable the clock controlling Ethernet on Snowball
  ARM: ux500: Stop passing ios_handler() as an MMCI power controlling call-back
  ARM: ux500: Apply the TCPM and TCDM locations and sizes to dbx5x0 DT
