From c38d444e44badc557cf29fdfdfb823604890ccfa Mon Sep 17 00:00:00 2001 From: Daniel Kolesa Date: Sat, 8 Aug 2020 22:44:58 +0200 Subject: drm/amd/display: add DCN support for aarch64 This adds ARM64 support into the DCN. This mainly enables support for Navi graphics cards. The dcn10 changes haven't been tested, since I don't have the relevant hardware available, but there is no way to conditionally disable them, so I've done them anyway.
