[PATCH 05/14] drm/i915: Clean up DVO pipe select bits

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

Parametrize the DVO pipe select bits.

For consistency with the new way of doing things, let's read out the
pipe select bits even when the port is disable, even though we don't
need that behaviour for asserts in this case.
