From ded5a35504367c1bdbd1d210ca0ba227352cec3d Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Fri, 25 Jun 2021 08:24:48 +0200 Subject: [PATCH] soc: mediatek: mmsys: Fix missing UFOE component in mt8173 table routing commit 25423731956b3d72bc35d336227c88ada49148e8 upstream. The UFOE (data compression engine) component needs to be enabled to have the imgtec gpu driver working. If we don't enable it we see a black screen. Looks like when we switched to use and array for setting the routing registers in commit 440147639ac7 ("soc: mediatek: mmsys: Use an array for setting the routing registers") we missed to add this component in the new routing table, it was present before that commit, so fix it by adding this component in the mt8173 routing table.
