Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next

Browse Source 
1) add LVDS support for mdp4 (tested with auo B101XTN01.0 panel)
 2) add B101XTN01.0 panel
 3) bit of gpu refactoring to prepare for addition of addition gpu
generations beyond just a3xx

* 'msm-next' of git://people.freedesktop.org/~robclark/linux:
  drm/msm/adreno: push dump/show stuff to base class
  drm/msm/adreno: bit of init refactoring
  drm/msm/adreno: move decision about what gpu to to load
  drm/msm/adreno: split adreno device out into it's own file
  drm/panel/simple: add optronics B101XTN01.0 (v3)
  drm/msm/mdp4: add LVDS panel support
  drm/msm/mdp4: fix blend setup with multiple crtcs
  drm/msm: update generated headers
