Imo, if no one cares about porting it to kms (which will give you an fbdev
driver for free), then we should throw it out. At least I thought staging
was only for stuff that had a reasonable chance to get mainlined. Not as a
dumping ground for drivers that people use, but don't bother to get ready
for mainline.

Yes, if no one is working to get it out of staging, that means no one
cares about it, and it needs to be removed from the tree.

Agreed. I was not working on getting it out of staging as there is no
place for it to go.
But, Teddy Wang told me that they have a working drm driver for it, but
it is not atomic like Daniel was asking for. If it is ok, then I can send
in a patch to remove the existing sm750 from staging and add the new sm750
drm driver to staging. And after it is ready, we can go ahead with moving
it out of staging to drm.
