[PATCH v2 0/9] drm: Third attempt at fixing the fb-helper .best_encoder() mess
From: Ville Syrjälä <ville.syrjala at linux.intel.com>
Changes from the previous version mainly involve Danoie's suggestion
of hiding the drm_encoder_find() in the iterator macro. I also polished
the msm and tilcdc cases a bit more with another small helper.

[PATCH v5 00/12] Enable GPU switching on pre-retina MacBook Pro
Enable GPU switching on the pre-retina MacBook Pro (2008 - 2013), v5.
The main obstacle on these machines is that the panel mode in VBIOS
is bogus. Fortunately gmux can switch DDC independently from the
display, thereby allowing the inactive GPU to probe the panel's EDID.
In short, vga_switcheroo and apple-gmux are amended with hooks to
switch DDC, DRM core is amended with a
