+title: Unisoc DRM master device
+

+
+description: |
+ The Unisoc DRM master device is a virtual device needed to list all
+ DPU devices or other display interface nodes that comprise the
+ graphics subsystem.
+
+ Unisoc's display pipeline have several components as below description,
+ multi display controllers and corresponding physical interfaces.
+ For different display scenarios, dpu0 and dpu1 maybe binding to different
+ encoder.
+
+ E.g:
+ dpu0 and dpu1 both binding to DSI for dual mipi-dsi display;
+ dpu0 binding to DSI for primary display, and dpu1 binding to DP for external display;
