Merge branch 'i2c/for-5.2' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux
Pull i2c updates from Wolfram Sang:
- API for late atomic transfers (e.g. to shut down via PMIC). We have a
seperate callback now which is called under clearly defined
conditions. In-kernel users are converted, too.
- new driver for the AMD PCIe MP2 I2C controller
- large refactoring for at91 and bcm-iproc (both gain slave support due
to this)
- and a good share of various driver improvements anf fixes
