SN65DSI86 DSI to eDP bridge chip -------------------------------- This is the binding for Texas Instruments SN65DSI86 bridge. http://www.ti.com/general/docs/lit/getliterature.tsp?genericPartNumber=sn65dsi86&fileType=pdf Required properties: - compatible: Must be "ti,sn65dsi86" - reg: i2c address of the chip, 0x2d as per datasheet - enable-gpios: gpio specification for bridge_en pin (active high) - vccio-supply: A 1.8V supply that powers up the digital IOs. - vpll-supply: A 1.8V supply that powers up the displayport PLL. - vcca-supply: A 1.2V supply that powers up the analog circuits. - vcc-supply: A 1.2V supply that powers up the digital core. Optional properties: - interrupts-extended: Specifier for the SN65DSI86 interrupt line. - gpio-controller: Marks the device has a GPIO controller. - #gpio-cells : Should be two. The first cell is the pin number and the second cell is used to specify flags. See ../../gpio/gpio.txt for more information. - #pwm-cells : Should be one. See ../../pwm/pwm.txt for description of the cell formats. - clock-names: should be "refclk" - clocks: Specification for input reference clock. The reference clock rate must be 12 MHz, 19.2 MHz, 26 MHz, 27 MHz or 38.4 MHz. - data-lanes: See ../../media/video-interface.txt - lane-polarities: See ../../media/video-interface.txt - suspend-gpios: specification for GPIO1 pin on bridge (active low) Required nodes: This device has two video ports. Their connections are modelled using the OF graph bindings specified in Documentation/devicetree/bindings/graph.txt. - Video port 0 for DSI input - Video port 1 for eDP output Example ------- edp-bridge@2d { compatible = "ti,sn65dsi86"; #address-cells = <1>; #size-cells = <0>; reg = <0x2d>; enable-gpios = <&msmgpio 33 GPIO_ACTIVE_HIGH>; suspend-gpios = <&msmgpio 34 GPIO_ACTIVE_LOW>; interrupts-extended = <&gpio3 4 IRQ_TYPE_EDGE_FALLING>; vccio-supply = <&pm8916_l17>; vcca-supply = <&pm8916_l6>; vpll-supply = <&pm8916_l17>; vcc-supply = <&pm8916_l6>; clock-names = "refclk"; clocks = <&input_refclk>; ports { #address-cells = <1>; #size-cells = <0>; port@0 { reg = <0>; edp_bridge_in: endpoint { remote-endpoint = <&dsi_out>; }; }; port@1 { reg = <1>; edp_bridge_out: endpoint { data-lanes = <2 1 3 0>; lane-polarities = <0 1 0 1>; remote-endpoint = <&edp_panel_in>; }; }; }; }
