This is based on Rob Clark's patch series that he submitted in October 2015 and I am resubmitting updated patches with his permission. See the individual patches for the changelog. This was tested with the GPU on a LG Nexus 5 (hammerhead) phone and this will work on other msm8974-based systems. For a summary of what currently works upstream on the Nexus 5, see my status page at https://masneyb.github.io/nexus-5-upstream/.
