It doesn't constitute + a device tree binding specification by itself but is meant to be referenced + by device tree bindings. + + When referenced from panel device tree bindings the properties defined in + this document are defined as follows. The panel device tree bindings are + responsible for defining whether each property is required or optional. + + Notice: this binding concerns DSI panels connected directly to a master + without any intermediate port graph to the panel. Each DSI master + can control one to four virtual channels to one panel. Each virtual + channel should have a node "panel" for their virtual channel with their + reg-property set to the virtual channel number, usually there is just + one virtual channel, number 0. + +properties: + $nodename: + pattern: "^dsi(@.*)?$" + + "#address-cells": + const: 1 + + "#size-cells": + const: 0 + +patternProperties: + "^panel@[0-3]$": + description: Panels connected to the DSI link + type: object + + properties: + reg: + minimum: 0 + maximum: 3 + description: + The virtual channel number of a DSI peripheral.
