Hmm, well this feels like a hack. DISPC driver doesn't know how the DSS
modules are arranged, which module belongs to which power domain, etc.

If it cannot be fixed in the arch code, I guess we could just have
dss_get_ctx_loss_count(void) function which always returns the
dss_core's ctx loss count, and define that on all the platforms omapdss
is used, the dss_core's ctx loss count is the same as ctx loss count for
all the dss submodules.

I think the above is true for all OMAPs. But it feels like a hack too,
but not as bad as the above patch.

Yes, a function taking in no platform device in dss's core.c would be
less hacky. I guess we would need this for now, because a solution in
omap_hwmod would be more complex and it may not be ready by the merge
window.

Ok. Can you cook up a patch and test it?

PM guys, does the above sound like an acceptable work-around?
