I think Andrzej answered it well, but I couldn't see what I did different from the Exynos driver, so I was puzzled that it would still work, but as it turns out that one breaks too. As far as I can tell, the proper fix is more complex and require embedding a struct device into struct drm_device like most subsystems do and create a link to that device instead of parent (dev->dev), because the parent device may be the parent of several subdevices, not just the drm_device, but also (in my case at least) the DSI devices. A typical case would be if the DSI host is in the same address range as the display controller (then it is usually represented by the same device). On other platforms the parent device may just be parent for the drm_device but we can't just assume that.
