Merge branch 'i2c/for-next' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"Highlights from the I2C subsystem for 3.18:
- new drivers for Axxia AM55xx, and Hisilicon hix5hd2 SoC.
- designware driver gained AMD support, exynos gained exynos7 support
The rest is usual driver stuff. Hopefully no lowlights this time"
