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

Mika Kahola mika.kahola at intel.com
Tue Dec 5 10:15:39 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.
