Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
This time around we have a mix of new hw enablement (mdp5 v1.3 / apq8084), plus devicetree and various upstream changes (mostly adapting to CCF vs downstream clk driver differences) for mdp4 / apq8064. With these drm/msm patches plus a few other small patchsets (from linaro qcom integration branch.. mostly stuff queued up for 3.17) we have the inforce ifc6410 board working, with gpu. Much nicer to work with than ancient vendor android branch :-) * 'msm-next' of git://people.freedesktop.org/~robclark/linux: drm/msm/hdmi: fix HDMI_MUX_EN gpio request typo drm/msm/hdmi: enable lpm-mux if it is present drm/msm/mdp5: add support for MDP5 v1.3 drm/msm: fix potential deadlock in gpu init drm/msm: use upstream iommu drm/msm: no mmu is only error if not using vram carveout drm/msm: fix BUG_ON() in error cleanup path drm/msm/mdp4: add mdp axi clk drm/msm: hdmi phy 8960 phy pll drm/msm: update generated headers drm/msm: DT support for 8960/8064 (v3) drm/msm: Implement msm drm fb_mmap callback function drm/msm: activate iommu support drm/msm: fix double struct_mutex acquire
