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

+Required properties:
+- compatible: "qcom,adreno-3xx"
+- reg: Physical base address and length of the controller's registers.
+- interrupts: The interrupt signal from the gpu.
+- clocks: device clocks
+  See ../clocks/clock-bindings.txt for details.
+- clock-names: the following clocks are required:
+  * "core_clk"
