[PATCH v5 00/12] Enable GPU switching on pre-retina MacBook Pro
...n.
Caution: Patch [09/12] depends on a new acpi_dev_present() API which
will land in 4.5 via Rafael J. Wysocki's tree.
I would particularly be interested in feedback on the handler flags
patch [01/12]. I'm not 100% happy with the number of characters
required to query the flags (e.g.: if (vga_switcheroo_handler_flags() &
VGA_SWITCHEROO_CAN_SWITCH_DDC)), but failed to come up with something
shorter. Thierry Reding used a struct of bools instead of a bitmask
for his recent drm_dp_link_caps patches. Maybe use that instead?

Thanks,
Luk...

[PATCH v5 11/12] drm/nouveau: Defer probe if gmux is present but its driver isn't
...ily switch DDC so that we can probe the panel's EDID.
The checks for CONFIG_VGA_ARB and CONFIG_VGA_SWITCHEROO are necessary
because if either of them is disabled but gmux is present, the driver
would never load, even if we're the active GPU. (vga_default_device()
would evaluate to NULL and vga_switcheroo_handler_flags() would
evaluate to 0.)

Use drm_for_each_connector_encoder_ids() for iterating
connector->encoder_ids[]. A bit more convenient not having
to deal with the implementation details.

[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.
