Thanks for that this really helps to test your patches.
And looks like something is broken for ARC PGU + ADV7511 with your tree:
-------------------------->8------------------------
adv7511: probe of 1-0039 failed with error -2
arcpgu e0017000.pgu: arc_pgu ID: 0x41440304
arcpgu e0017000.pgu: assigned reserved memory node frame_buffe
r@9e000000
[drm] Cannot find any crtc or sizes
[drm] Cannot find any crtc or sizes
[drm] Initialized arcpgu 1.0.0 20160219 for e0017000.pgu on minor 0
-------------------------->8------------------------

That's what I see on vanilla 4.14 kernel:
-------------------------->8------------------------
arcpgu e0017000.pgu: arc_pgu ID: 0x41440304
arcpgu e0017000.pgu: assigned reserved memory node frame_buffer@9e000000
Console: switching to colour frame buffer device 160x45
arcpgu e0017000.pgu: fb0:  frame buffer device
[drm] Initialized arcpgu 1.0.0 20160219 for e0017000.pgu on minor 0
-------------------------->8------------------------

Any thoughts?
