     See Documentation/devicetree/bindings/display/ti/ti,omap-dss.txt for generic
     description about OMAP Display Subsystem bindings.
     
     DSS Core
     --------
     
    Required properties:
    - compatible: "ti,dra7-dss"
    - reg: address and length of the register spaces for 'dss'
    - ti,hwmods: "dss_core"
    - clocks: handle to fclk
    - clock-names: "fck"
    - syscon: phandle to control module core syscon node
    
    Optional properties:
    
    Some DRA7xx SoCs have one dedicated video PLL, some have two. These properties
    can be used to describe the video PLLs:
    
    - reg: address and length of the register spaces for 'pll1_clkctrl',
      'pll1', 'pll2_clkctrl', 'pll2'
    - clocks: handle to video1 pll clock and video2 pll clock
    - clock-names: "video1_clk" and "video2_clk"
    
    Required nodes:
    - DISPC
    
    Optional nodes:
    - DSS Submodules: HDMI
    - Video port for DPI output
    
    DPI Endpoint required properties:
    - data-lines: number of lines used
    
    
    DISPC
    -----
    
    Required properties:
    - compatible: "ti,dra7-dispc"
    - reg: address and length of the register space
    - ti,hwmods: "dss_dispc"
    - interrupts: the DISPC interrupt
    - clocks: handle to fclk
    - clock-names: "fck"
    
    Optional properties:
    - max-memory-bandwidth: Input memory (from main memory to dispc) bandwidth limit
                            in bytes per second
    
    
    HDMI
    ----
    
    Required properties:
    - compatible: "ti,dra7-hdmi"
    - reg: addresses and lengths of the register spaces for 'wp', 'pll', 'phy',
           'core'
    - reg-names: "wp", "pll", "phy", "core"
    - interrupts: the HDMI interrupt line
    - ti,hwmods: "dss_hdmi"
    - vdda-supply: vdda power supply
    - clocks: handles to fclk and pll clock
    - clock-names: "fck", "sys_clk"
    
    Optional nodes:
    - Video port for HDMI output
    
    HDMI Endpoint optional properties:
    - lanes: list of 8 pin numbers for the HDMI lanes: CLK+, CLK-, D0+, D0-,
      D1+, D1-, D2+, D2-. (default: 0,1,2,3,4,5,6,7)
