[PATCH 10/21] drm/i915: split fdi link training from display vtable.

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

 



From: Dave Airlie <airlied@xxxxxxxxxx>

It may make sense to merge this with display again later,
however the fdi use of the vtable is limited to only a
few generations.
