    1 * Texas Instruments TV7002 video decoder
    2 
    3 The TVP7002 device supports digitizing of video and graphics signal in RGB and
    4 YPbPr color space.
    5 
    6 Required Properties :
    7 - compatible : Must be "ti,tvp7002"
    8 
    9 Optional Properties:
   10 - hsync-active: HSYNC Polarity configuration for the bus. Default value when
   11   this property is not specified is <0>.
   12 
   13 - vsync-active: VSYNC Polarity configuration for the bus. Default value when
   14   this property is not specified is <0>.
   15 
   16 - pclk-sample: Clock polarity of the bus. Default value when this property is
   17   not specified is <0>.
   18 
   19 - sync-on-green-active: Active state of Sync-on-green signal property of the
   20   endpoint.
   21   0 = Normal Operation (Active Low, Default)
   22   1 = Inverted operation
   23 
   24 - field-even-active: Active-high Field ID output polarity control of the bus.
   25   Under normal operation, the field ID output is set to logic 1 for an odd field
   26   (field 1) and set to logic 0 for an even field (field 0).
   27   0 = Normal Operation (Active Low, Default)
   28   1 = FID output polarity inverted
   29

   38                 tvp7002@5c {
   39                         compatible = "ti,tvp7002";
   40                         reg = <0x5c>;
   41 
   42                         port {
   43                                 tvp7002_1: endpoint {
   44                                         hsync-active = <1>;
   45                                         vsync-active = <1>;
   46                                         pclk-sample = <0>;
   47                                         sync-on-green-active = <1>;
   48                                         field-even-active = <0>;
   49                                 };
