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

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