From 8eeb3946feeb00486ac0909e2309da87db8988a5 Mon Sep 17 00:00:00 2001 From: Wangyan Wang Date: Tue, 9 Apr 2019 14:53:05 +0800 Subject: drm/mediatek: using new factor for tvdpll for MT2701 hdmi phy This is the second step to make MT2701 HDMI stable. The factor depends on the divider of DPI in MT2701, therefore, we should fix this factor to the right and new one.
