0014 This binding file is a collection of the DSI panels that
0015 are usually driven in command mode. If no backlight is
0016 referenced via the optional backlight property, the DSI
0017 panel is assumed to have native backlight support.
0018 The panel may use an OF graph binding for the association
0019 to the display, or it may be a direct child node of the
0020 display.

0039 vddi-supply:
0040 description:
0041 Display panels require power to be supplied. While several panels need
0042 more than one power supply with panel-specific constraints governing the
0043 order and timings of the power supplies, in many cases a single power
0044 supply is sufficient, either because the panel has a single power rail, or
0045 because all its power rails can be driven by the same supply. In that case
0046 the vddi-supply property specifies the supply powering the panel as a
0047 phandle to a regulator.
0048
0049 vpnl-supply:
0050 description:
0051 When the display panel needs a second power supply, this property can be
0052 used in addition to vddi-supply. Both supplies will be enabled at the
0053 same time before the panel is being accessed.
