     13  The Unisoc DRM master device is a virtual device needed to list all
     14  DPU devices or other display interface nodes that comprise the
     15  graphics subsystem.
     16
     17  Unisoc's display pipeline have several components as below description,
     18  multi display controllers and corresponding physical interfaces.
     19  For different display scenarios, dpu0 and dpu1 maybe binding to different
     20  encoder.
     21
     22  E.g:
     23  dpu0 and dpu1 both binding to DSI for dual mipi-dsi display;
     24  dpu0 binding to DSI for primary display, and dpu1 binding to DP for external display;
