Merge branch 'i2c/for-mergewindow' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
"I2C has a smaller pull reuest this time:
- new driver for I2C virtio
- removal of PMC SMP driver because platform is already gone
- IRQ probing and DMAENGINE API cleanups
- add SI metric prefix definitions to units.h
- beginning of i801 refactorization
- a few driver improvements"
