It turns out this patch breaks probing for the built-in case [1]. As a
result, imx-drm probing is broken in v4.6. I have sent a patch [2] to
fix the issue by matching the crtc components not against dev->of_node
but against an of_node pointer stored in platform data.
[1] http://comments.gmane.org/gmane.linux.ports.arm.kernel/499839
Message-ID: <20160513123336.6996dd89@xxxxxxx-ro>
[2] https://patchwork.kernel.org/patch/9081661/
Message-ID: <1463062124-20256-1-git-send-email-p.zabel@xxxxxxxxxxxxxx>
Could we apply that or revert commit 407c9eba7897 ("drm/imx: Remove
of_node assignment from ipuv3-crtc driver probe") for the time being?
Either way, applying this patch without doing either of the two will
break imx-drm probing in v4.4 and v4.5 stable, too.

Philipp
