Hi,
I just tested the latest drm-next branch on Freescale/NXP ls1021a-twr, and
got some log below. And fsl-dcu not works.
Since "drm-next" merged some branch , use git bisect had some problem ,
so I manually checked out that "fsl-dcu" works at d761701c55a99598477f3cb25c03d939a7711e74
Hm, that commit seems rather unrelated... is that what git bisect told you?
Yeah, It seems having nothing to do with the issue.
I manually found that commit, "fsl-dcu" not works at that commit, but works at commit before it.
But I have no idea of this.
I guess my last pull request could be related to that, so maybe you can check those two commits manually: 077d67374e ("drm: rcar-du: Fix compilation warning") vs. 0449eefe2d ("drm/fsl-dcu: increment version and date")
Thanks, I will check those two commits.
And not works now. some log below:
[drm] Initialized drm 1.1.0 20060810
panel supply power not found, using dummy regulator
[drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
[drm] No driver support for vblank timestamp query.

It seems that interrupt do not work properly. Could it be that work elsewhere caused that issue?
I don't know so far.
Thanks, Meng
