Merge tag 'tegra-for-3.10-fixes-for-mmc' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into mmc-next
ARM: tegra: DT-related fixes needed by the MMC tree
In order to convert the Tegra MMC driver to using mmc_of_parse(), some
bugs in the Tegra device-tree content need to be fixed first; it's
currently wrong but unused, and mmc_of_parse() causes that data to be
used for the first time.
