title: SDE DP
description: |
sde-dp is the master Display Port device which supports DP host controllers that are compatible
with VESA Display Port interface specification.
msm_ext_disp is a device which manages the interaction between external
display interfaces, e.g. Display Port, and the audio subsystem.
[Optional child nodes]: These nodes are for devices which are
dependent on msm_ext_disp. If msm_ext_disp is disabled then
these devices will be disabled as well. Ex. Audio Codec device.
