[PULL REQUEST] i2c for 4.1

[Wolfram Sang]

Linus,

here is the i2c pull request for 4.1. Most notable:

* introducing the i2c_quirk infrastructure. Now, flaws of I2C
  controllers can be described and the core will check if the
  flaws collide with the messages to be sent

* wait_for_completion return type cleanup series

* new drivers for Digicolor, Netlogic XLP, Ingenic JZ4780

* updates to the I2C slave framework which include API changes. Its
  only user was updated, too. Documentation was finally added

* changed dynamic bus numbering for the DT case. This could change bus
  numbers for users. However, it fixes a collision where dynamic and
  static busses request the same id.

* driver bugfixes, cleanups

Please pull.

Thanks,

   Wolfram
