It shouldn't matter when omapdrm is initialized. omapdrm should wait
until it has all the displays.

I tried to trace this. I assume, that your "should wait until it has
all the displays" refers to the code in "omap_connect_dssdevs()".
Unfortunately that code does not work correctly:

Indeed, sorry about the confusion. Apparently I was talking about TI's
kernel, which has fixes for this.

I have actually posted the patches, along with a lot of other stuff,
last Nov. See "[PATCH 00/36] drm/omap: miscallaneous improvements"
series. The patches 23-25 should fix this particular issue.

Ok, I got both initializing correctly by cherry-picking (and
rebasing) the following patches:

drm/omap: Use omapdss_stack_is_ready() to check that the display stack is up
drm/omap: dss: Support for detecting display stack readiness
drm/omap: move dss_initialized to omapdss-base
drm/omap: add omapdss-base.ko
drm/omap: dss: Functions to check components in the display/output list

What's the plan with regarding patchset?
