    1 Texas Instruments AM437x CAMERA (VPFE)
    2 --------------------------------------
    3 
    4 The Video Processing Front End (VPFE) is a key component for image capture
    5 applications. The capture module provides the system interface and the
    6 processing capability to connect RAW image-sensor modules and video decoders
    7 to the AM437x device.
    8 
    9 Required properties:
   10 - compatible: must be "ti,am437x-vpfe"
   11 - reg: physical base address and length of the registers set for the device;
   12 - interrupts: should contain IRQ line for the VPFE;
   13 - ti,am437x-vpfe-interface: can be one of the following,
   14         0 - Raw Bayer Interface.
   15         1 - 8 Bit BT656 Interface.
   16         2 - 10 Bit BT656 Interface.
   17         3 - YCbCr 8 Bit Interface.
   18         4 - YCbCr 16 Bit Interface.
   19 
   20 VPFE supports a single port node with parallel bus. It should contain one
   21 'port' child node with child 'endpoint' node. Please refer to the bindings
   22 defined in Documentation/devicetree/bindings/media/video-interfaces.txt.
