[PATCH 3/5] drm/mediatek: change compatible name for mt8195
Jason-JH.Lin
jason-jh.lin at mediatek.com
Wed Sep 14 11:23:29 PDT 2022
In mt8195, vdosys0 and vdosys1 are 2 different function blocks
for mediatek-drm, so using 2 compatible instead of identifying
multiple mmsys by io_start.
Fixes: 7266e90a51a3 ("drm/mediatek: Add mediatek-drm of vdosys0 support for mt8195")
