[PATCH 04/17] drm/armada: use core of primary update_plane for mode set
Russell King
rmk+kernel at armlinux.org.uk
Tue Jul 10 10:32:28 UTC 2018
Use the core of the update_plane method to configure the primary plane
within mode_set() rather than duplicating this code. This moves us
closer to the same code structure that the atomic modeset transitional
helpers will use.
