+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.
