Public bug reported:

The Open Power machines need the driver that was merged in 3.19 backported. The 
commit upstream
is 470834508f87877f680738a10a305280582c7aed "i2c: Driver to expose PowerNV 
platform i2c busses"

This exposes the i2c busses of the machine which are controlled via the OPAL 
firmware. This is among
other things, necessary for manufacturing configuration of VPDs etc..., but 
will also enable Linux access
to some i2c devices such as the TPM.

We wish to have this in utopic and if possible trusty.

** Affects: linux (Ubuntu)
