Merge tag 'davinci-for-v3.10/dt' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci into next/soc
From Sekhar Nori <nsekhar@ti.com>:
v3.10 DT updates for DaVinci
The pull request adds support for MMC/SD and regulator on DA850 EVM.
* tag 'davinci-for-v3.10/dt' of git://git.kernel.org/pub/scm/linux/kernel/git/nsekhar/linux-davinci:
ARM: davinci: da850: override mmc DT node device name
ARM: davinci: da850: add mmc DT entries
mmc: davinci_mmc: add DT support
ARM: davinci: da850: add tps6507x regulator DT data
ARM: regulator: add tps6507x device tree data
Merged into soc branch rather than DT branch to avoid circular dependencies.
