The single LVDS link has already been documented in this binding doc. Please find the "properties" above where only "port@0" and "port@2" are required. imx8mp-evk-lvds0-imx-lvds-hdmi.dtso and imx8mp-evk-lvds1-imx-lvds-hdmi.dtso added in patch 7 support the NXP adapter card with single LVDS link. > > Cheers, > Biju > >> + >> + required: >> + - port@0 >> + - port@1 >> + - port@2 >> + >> + allOf: >> + - if: >> + properties: >> + port@0: >> + required: >> + - dual-lvds-odd-pixels >> + then: >> + properties: >> + port@1: >> + properties: >> + dual-lvds-odd-pixels: false >> + >> + - if: >> + properties: >> + port@0: >> + required: >> + - dual-lvds-even-pixels >> + then: >> + properties: >> + port@1: >> + properties: >> + dual-lvds-even-pixels: false >> + >> +required: >> + - compatible >> + - reg >> + - ivdd-supply >> + - ovdd-supply >> + - txavcc18-supply >> + - txavcc33-supply >> + - pvcc1-supply >> + - pvcc2-supply >> + - avcc-supply >> + - anvdd-supply >> + - apvdd-supply >> + - ports >> + >> +additionalProperties: false >> + >> +examples: >> + - | >> + /* single-link LVDS input */ >> + #include <dt-bindings/gpio/gpio.h> >> + >> + i2c { >> + #address-cells = <1>; >> + #size-cells = <0>; >> + >> + hdmi@4c { >> + compatible = "ite,it6263"; >> + reg = <0x4c>; >> + reset-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>; >> + ivdd-supply = <®_buck5>; >> + ovdd-supply = <®_vext_3v3>; >> + txavcc18-supply = <®_buck5>; >> + txavcc33-supply = <®_vext_3v3>; >> + pvcc1-supply = <®_buck5>; >> + pvcc2-supply = <®_buck5>; >> + avcc-supply = <®_vext_3v3>; >> + anvdd-supply = <®_buck5>; >> + apvdd-supply = <®_buck5>; >> + >> + ports { >> + #address-cells = <1>; >> + #size-cells = <0>; >> + >> + port@0 { >> + reg = <0>; >> + >> + it6263_lvds_link1: endpoint { >> + remote-endpoint = <&ldb_lvds_ch0>; >> + }; >> + }; >> + >> + port@2 { >> + reg = <2>; >> + >> + it6263_out: endpoint { >> + remote-endpoint = <&hdmi_in>; >> + }; >> + }; >> + }; >> + }; >> + }; >> + >> + - | >> + /* dual-link LVDS input */ >> + #include <dt-bindings/gpio/gpio.h> >> + >> + i2c { >> + #address-cells = <1>; >> + #size-cells = <0>; >> + >> + hdmi@4c { >> + compatible = "ite,it6263"; >> + reg = <0x4c>; >> + reset-gpios = <&gpio1 10 GPIO_ACTIVE_LOW>; >> + ivdd-supply = <®_buck5>; >> + ovdd-supply = <®_vext_3v3>; >> + txavcc18-supply = <®_buck5>; >> + txavcc33-supply = <®_vext_3v3>; >> + pvcc1-supply = <®_buck5>; >> + pvcc2-supply = <®_buck5>; >> + avcc-supply = <®_vext_3v3>; >> + anvdd-supply = <®_buck5>; >> + apvdd-supply = <®_buck5>; >> + >> + ports { >> + #address-cells = <1>; >> + #size-cells = <0>; >> + >> + port@0 { >> + reg = <0>; >> + dual-lvds-odd-pixels; >> + >> + it6263_lvds_link1_dual: endpoint { >> + remote-endpoint = <&ldb_lvds_ch0>; >> + }; >> + }; >> + >> + port@1 { >> + reg = <1>; >> + dual-lvds-even-pixels; >> + >> + it6263_lvds_link2_dual: endpoint { >> + remote-endpoint = <&ldb_lvds_ch1>; >> + }; >> + }; >> + >> + port@2 { >> + reg = <2>; >> + >> + it6263_out_dual: endpoint { >> + remote-endpoint = <&hdmi_in>; >> + }; >> + }; >> + }; >> + }; >> + }; >> -- >> 2.34.1 >> > -- Regards, Liu Ying
