[Intel-gfx] [PATCH v2] drm/i915: Generalize definition for crtc mask

Mika Kahola mika.kahola at intel.com
Wed Dec 13 09:25:16 UTC 2017


crtc_mask is defined explicitly defined for a certain number of pipes per
platform. Let's generalize this in a way that crtc_mask dependens only on
the number of pipes defined in device info.

v2: Use BIT() macro wherever possible (Ville)
    Drop generalization for all other connectors except DDI (Ville)
    Fix DP-MST crtc mask to be dependent only on pipe (Ville)
