[PATCH 13/20] drm/armada: switch legacy modeset to atomic modeset
Russell King
rmk+kernel at armlinux.org.uk
Tue Jul 10 10:42:18 UTC 2018
Switch the legacy set_config() method to use the atomic modeset
helper, which allows us to get rid of the legacy dpms, prepare,
commit, mode_set, mode_set_base and disable helper methods.
