From: Evan Quan Date: Mon, 17 Sep 2018 06:59:54 +0000 (+0800) Subject: drm/amd/powerplay: retrieve the updated clock table after OD X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=32f2a0d117769bdca7f7ee6224659f2c688ebc85;p=openwrt%2Fstaging%2Fblogic.git drm/amd/powerplay: retrieve the updated clock table after OD With OD settings applied, the clock table will be updated accordingly. We need to retrieve the new clock tables then.
