   14   This binding file is a collection of the DSI panels that
   15   are usually driven in command mode. If no backlight is
   16   referenced via the optional backlight property, the DSI
   17   panel is assumed to have native backlight support.
   18   The panel may use an OF graph binding for the association
   19   to the display, or it may be a direct child node of the
   20   display.

   39   vddi-supply:
   40     description:
   41       Display panels require power to be supplied. While several panels need
   42       more than one power supply with panel-specific constraints governing the
   43       order and timings of the power supplies, in many cases a single power
   44       supply is sufficient, either because the panel has a single power rail, or
   45       because all its power rails can be driven by the same supply. In that case
   46       the vddi-supply property specifies the supply powering the panel as a
   47       phandle to a regulator.
   48 
   49   vpnl-supply:
   50     description:
   51       When the display panel needs a second power supply, this property can be
   52       used in addition to vddi-supply. Both supplies will be enabled at the
   53       same time before the panel is being accessed.
