I'm also not sure how to specify that both data-lanes and lane-polarities need to have the same number of items, maybe dependencies: data-lanes: [lane-polarities] > + > + ports: > + type: object > + > + properties: > + "#address-cells": > + const: 1 > + > + "#size-cells": > + const: 0 > + > + port@0: > + type: object > + additionalProperties: false > + > + description: > + Video port for MIPI DSI input > + > + properties: > + reg: > + const: 0 > + > + patternProperties: > + endpoint: If there's a single endpoint, you don't need patternProperties, it can be specified in properties. > + type: object > + additionalProperties: false > + > + properties: > + remote-endpoint: true > + > + required: > + - reg > + > + port@1: > + type: object > + additionalProperties: false > + > + description: > + Video port for eDP output (panel or connector). > + > + properties: > + reg: > + const: 1 > + > + patternProperties: > + endpoint: Same here. > + type: object > + additionalProperties: false > + > + properties: > + remote-endpoint: true > + > + required: > + - reg > + > + required: > + - "#address-cells" > + - "#size-cells" > + - port@0 > + - port@1 > + > +required: > + - compatible > + - reg > + - enable-gpios > + - vccio-supply > + - vpll-supply > + - vcca-supply > + - vcc-supply > + - ports > + > +additionalProperties: false > + > +examples: > + - | > + #include <dt-bindings/clock/qcom,rpmh.h> > + #include <dt-bindings/gpio/gpio.h> > + #include <dt-bindings/interrupt-controller/irq.h> > + > + i2c1 { > + #address-cells = <1>; > + #size-cells = <0>; > + > + bridge@2d { > + compatible = "ti,sn65dsi86"; > + reg = <0x2d>; > + > + interrupt-parent = <&tlmm>; > + interrupts = <10 IRQ_TYPE_LEVEL_HIGH>; > + > + enable-gpios = <&tlmm 102 GPIO_ACTIVE_HIGH>; > + > + vpll-supply = <&src_pp1800_s4a>; > + vccio-supply = <&src_pp1800_s4a>; > + vcca-supply = <&src_pp1200_l2a>; > + vcc-supply = <&src_pp1200_l2a>; > + > + clocks = <&rpmhcc RPMH_LN_BB_CLK2>; > + clock-names = "refclk"; > + > + ports { > + #address-cells = <1>; > + #size-cells = <0>; > + > + port@0 { > + reg = <0>; > + endpoint { > + remote-endpoint = <&dsi0_out>; > + }; > + }; > + > + port@1 { > + reg = <1>; > + endpoint { > + remote-endpoint = <&panel_in_edp>; > + }; > + }; > + }; > + }; > + }; > + -- Regards, Laurent Pinchart
