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

37 description: DSI virtual channel
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.
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.
