Title:
  OpenPower needs backport of PowerNV OPAL i2c driver

Status in linux package in Ubuntu:
  Fix Released
Status in linux source package in Trusty:
  Invalid
Status in linux source package in Utopic:
  Fix Released

Bug description:
  [Impact]
  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.

  [Fix]
  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"
  $ git describe --contains 470834508f87877f680738a10a305280582c7aed
  v3.19-rc1~22^2~7

  [Test Case]
  modprobe i2c-opal
