ti-sn65dsi86 bridge is enumerated as a runtime device. When suspend is triggered, PM core adds a refcount on all the devices and calls device suspend, since usage count is already incremented, runtime suspend will not be called and it kept the bridge regulators and gpios ON which resulted in platform not entering into XO shutdown.
Add changes to force suspend on the runtime device during pm sleep.

I think this patch is good to go now (has both Stephen's and my reviews). I noticed that Neil landed my other patches to this driver recently (thanks!) and wondered why he didn't land this one. Then, I realized that you didn't send it to him or the other bridge maintainer. :( Have you tried running get_maintainer?

In any case, unless someone has extra feedback on this patch I think it's ready to land.
Neil: If you're willing to land this patch too, can you let Harigovindan know if it needs to be re-sent with you in the "To:" list or if you can find it on the dri-devel list?
Sorry missed this one,
Applying to drm-misc-next

Thanks!
