Merge branch 'i2c-embedded/for-next' of git://git.pengutronix.de/git/wsa/linux
Pull embedded i2c changes from Wolfram Sang:
"Changes for the "embedded" part of the I2C subsystem:
- lots of devicetree conversions of drivers (and preparations for
that)
- big cleanups for drivers for OMAP, Tegra, Nomadik, Blackfin
- Rafael's struct dev_pm_ops conversion patches for I2C
- usual driver cleanups and fixes
All patches have been in linux-next for an apropriate time and all
patches touching files outside of i2c-folders should have proper acks
from the maintainers."
