7 title: Common Properties for DSI Display Panels

13   This document defines device tree properties common to DSI, Display
18   When referenced from panel device tree bindings the properties defined in
19   this document are defined as follows. The panel device tree bindings are
22   Notice: this binding concerns DSI panels connected directly to a master
23   without any intermediate port graph to the panel. Each DSI master
24   can control one to four virtual channels to one panel. Each virtual
25   channel should have a node "panel" for their virtual channel with their
26   reg-property set to the virtual channel number, usually there is just
