     13  This document defines device tree properties common to DSI, Display
     14  Serial Interface controllers and attached panels. It doesn't constitute
     15  a device tree binding specification by itself but is meant to be referenced
     16  by device tree bindings.
     17
     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
     20  responsible for defining whether each property is required or optional.
     21
     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
     27  one virtual channel, number 0.

     49          The virtual channel number of a DSI peripheral. Must be in the range
     50          from 0 to 3, as DSI uses a 2-bit addressing scheme. Some DSI
     51          peripherals respond to more than a single virtual channel. In that
     52          case the reg property can take multiple entries, one for each virtual
     53          channel that the peripheral responds to.

     58          Should be enabled if the host is being used in conjunction with
     59          another DSI host to drive the same peripheral. Hardware supporting
     60          such a configuration generally requires the data on both the busses
     61          to be driven by the same clock. Only the DSI host instance
     62          controlling this clock should contain this property.

     66        description:
     67          The best option is usually to run a panel in command mode, as this
     68          gives better control over the panel hardware. However for different
     69          reasons like broken hardware, missing features or testing, it may be
     70          useful to be able to force a command mode-capable panel into video
     71          mode.
