From d462fcf5012bdffb8f182eae01f73439bf4176f9 Mon Sep 17 00:00:00 2001 From: Bhawanpreet Lakha Date: Tue, 6 Aug 2019 17:43:53 -0400 Subject: [PATCH] drm/amd/display: Update hdcp display config [Why] We need to update the hdcp display parameter whenever the link is updated, so the next time there is an update to hdcp we have the latest display info [How] Create a callback, and use this anytime there is a change in the link. This will be used later by the dm.
