Only specific N value (0x8000) would be acceptable for LG
LP140WF6-SPM1 eDP panel which is running at asynchronous
clock mode. With the other N value, it will enter BITS mode
and display black screen. This patch series set constant N
value for specific sink/branch device that would cover
similar issue.
