Subject: [PATCH 09/10] drm/i915: clean up plane bpp confusion
Date: Fri, 22 Feb 2013 00:56:53 +0100	[thread overview]
Message-ID: <1361491014-13888-10-git-send-email-daniel.vetter@ffwll.ch> (raw)
In-Reply-To: <1361491014-13888-1-git-send-email-daniel.vetter@ffwll.ch>

- There is no 16bpc linear color format in our hw. gen4+ has a 16 bpc
  float layout, but we don't really support it.
- 10bpc is a gen4+ feature, fix up the support for it.
- Update_plane should never see a wrong fb bpp value, BUG in the
  corresponding cases.

v2: Rebase on top of Ville's plane pixel layout changes.

v3: Actually drop the old gen4 check for 10bpc planes, spotted
by Ville Syrjälä.
