From: Xingyue Tao Date: Fri, 16 Feb 2018 21:29:13 +0000 (-0500) Subject: drm/amd/display: add psr_version to stream X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=85075fa04287dce81397dab75af0992274727b82;p=openwrt%2Fstaging%2Fblogic.git drm/amd/display: add psr_version to stream Brightness could not be changed for some panels whose DPCD_version is below 1.2 Now psr_version is added into stream, and it copies from the displayTarget's psr_version. It checks if the stream's psr_versio is non-zero and sets the vsc info packet revision now.
