Merge tag 'tegra-for-3.7-drivers-i2c' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/drivers

From Stephen Warren:

ARM: tegra: i2c driver enhancements mostly related to clocking

This branch contains a number of fixes and cleanups to the Tegra I2C
driver related to clocks. These are based on the common clock conversion
in order to avoid duplicating the clock driver changes before and after
the conversion. Finally, a bug-fix related to I2C_M_NOSTART is included.

This branch is based on previous pull request tegra-for-3.7-common-clk.
