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

Pull i2c fixes from Wolfram Sang:
 "Two I2C driver bugfixes.

  The 'VLLS mode support' patch should have been entitled 'reconfigure
  pinctrl after suspend' to make the bugfix more clear. Sorry, I missed
  that, yet didn't want to rebase"

* 'i2c/for-current' of git://git.kernel.org/pub/scm/linux/kernel/git/wsa/linux:
  i2c: imx-lpi2c: add VLLS mode support
  i2c: i2c-cadence: Initialize configuration before probing devices
