Subject: [RFC PATCH 00/14] CAMSS support for MSM8974

This RFC series adds support for CAMSS and CCI that are found on
msm8974, including the OV8865 found on the FP2.

The only reason it's marked RFC is that CAMSS doesn't behave properly on
this SoC without the last commit which is obviously not upstreamable.
Not sure if this should be a blocker for including most of the other
patches because other than that it seems to work fine and I can get a
picture from the camera sensor. When/if msm8974 gets IOMMU support I
hope this should be resolved and it works without this hack.

I think at least the CCI patches could get applied as they're not
dependent on the CAMSS hack?
