[Intel-gfx] [PATCH 00/10] drm/uapi: Validate mode flags/type, and deprecate some of them

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

I recently realized that we're not validating the mode flags/type
passed in from userspace. Let's try to fix that.

I'd also like to entirely eliminate some of the more crazy mode flags.
PIXMUX and BCAST look pretty easy, so I've targetted them first.

Ideally I'd like to kill DBLCLK, CLKDIV2, HSKEW, DBLSCAN, and vscan
as well. IMO there's no good reason to expose any of that to userspace,
and instead it should all be handled internally by the drivers.
Unfortunately all of those seem to be used to some degree by a handful
of drivers.

I also tried to nuke some of the crazy mode types.
