From: Rex Zhu Date: Thu, 15 Jun 2017 06:02:51 +0000 (+0800) Subject: drm/amd/powerplay: refine avfs enable code on fiji. X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=b37afd41a1f5a7d9dbc4cc6ede62e590a31e2192;p=openwrt%2Fstaging%2Fblogic.git drm/amd/powerplay: refine avfs enable code on fiji. 1. simplify avfs state switch. 2. delete save/restore VFT table functions as not support by fiji. 3. implement thermal_avfs_enable funciton.
