[PATCH 14/51] drm/amd/display: get rid of cur_clks from dcn_bw_output

Harry Wentland harry.wentland at amd.com
Tue Jun 19 21:10:21 UTC 2018


From: Dmytro Laktyushkin <Dmytro.Laktyushkin at amd.com>

Cleans up dcn_bw_output to only contain calculated info,
actual programmed values will now be stored in respective blocks.
