Merge branch 'i2c/for-mergewindow' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux

Pull i2c updates from Wolfram Sang:
 "Mostly driver updates and refactorization.

  The removal of the XLR driver and the i801 refactoring stand out a
  little. In the core, we enabled async suspend/resume for I2C
  controllers and their clients. No issues were reported during the test
  phase in -next. We will see how this goes for mainline"

+  define USI node in device tree file, choosing "i2c" configuration. Please see
+  Documentation/devicetree/bindings/soc/samsung/exynos-usi.yaml for details.
