[PATCH v2 0/8] i2c: bcm2835: Bring in changes from downstream

From: Noralf TrÃnnes
Date: Tue Sep 27 2016 - 07:58:03 EST

This patchset tries to bring in the lessons learned in the downstream
driver i2c-bcm2708. The downstream clock stretcing timeout patch has
been left out since clock stretching is broken/unreliable on this
controller, so no point in setting it.

This second version of the patchset has been expanded to try and
encompass all the differences between mainline and downstream.
Hopefully downstream can now start using this driver.

Thanks to Martin for jogging my memory with his comments which led to
the discovery that interrupt could be used instead of polling for the
Transfer Active state.
