   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.
