Merge branch 'msm-next' of git://people.freedesktop.org/~robclark/linux into drm-next
1) includes all the drm/msm side of things for upstream kernel working
on dragonboard 410c (still some pending work on adv7533 bridge chip)
2) initial support for msm8x94 (snapdragon 810)
3) support for msm8x74v1 (in addition to existing v2 support)
4) support for dma planes on mdp5 (additional planes that cannot scale/csc)
5) more yuv format support for mdp5 (single plane vyuy/uyvy/yuyv/yvyu,
two plane nv16/nv61, and three plane yuv420/yvu420)
6) rotation support for mdp5
7) initial hdcp support
8) fixes, etc
* 'msm-next' of git://people.freedesktop.org/~robclark/linux: (46 commits)
