* drm/amd/display: fix dcn pipe reset sequenceDmytro Laktyushkin2017-09-261-0/+1
| | | | | | | | | | | | This change fixes dcn10 front end reset sequence. Previously we would reset front end during flip which led to issues in certain MPO and 4k/5k scenarios. We would also never properly power gate our front end.
