     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.yaml 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
