Subject: [PATCH v2 0/2] Qualcomm Universal Peripheral (QUP) I2C controller

Picking up Ivans i2c-qup submission from a few months back, as I've now
tested and corrected some minor things. I also introduced changes based
on the review of v1.

Changes from v1:
 - Cleaned up device tree binding example.
 - Refrased device tree bindings.
 - Following changes in the i2c framework.
 - Use the core clock to calculate divider for the bus clock, instead of
   explicitly setting it.
 - Remove explicit pinctrl settting.
 - Split/renamed qup_i2c_enable(bool) into enable/disable functions.
 - Return value was overwritten on error in write_one/read_one.
 - Initialize the i2c core every time, so that we actually can execute
   more than 1 transmission per xfer.

  i2c: qup: Add device tree bindings information
  i2c: New bus driver for the QUP I2C controller
