We have a custom x86 board with:

    - A soldered down cx23888

    - Four composite inputs feeding the cx23888. No tuner.
      We're only looking at the four composite inputs.

    - FC13 with a 2.6.33.4 kernel.

The cx23885 driver loads and I get /dev/video0 but when I try to
cat /dev/video0 I get data but it's not an mpeg file.

Can anyone point me to some documentation which tells how to set
up the cx23885_board board structure and what other
initialization might need to be done?


In the cx23885 driver I modified cx23885-cards.c to add an
entry for our hardware.

struct cx23885_board cx23885_boards[] = {

   [CX23885_BOARD_ECU] = {
       .name       = "custom board",
       .porta      = CX23885_ANALOG_VIDEO,
       .portb      = CX23885_MPEG_ENCODER,
       .clk_freq   = 50000000,
       .input          = {{
           .type   = CX23885_VMUX_COMPOSITE1,
           .vmux   = 0,
       }, {
           .type   = CX23885_VMUX_COMPOSITE2,
           .vmux   = 1,
       }, {
           .type   = CX23885_VMUX_COMPOSITE3,
           .vmux   = 2,
       }, {
           .type   = CX23885_VMUX_COMPOSITE4,
           .vmux   = 3,
       } },
   },

cx23885_subids

   }, {
       .subvendor = 0x0000,
       .subdevice = 0x0000,
       .card      = CX23885_BOARD_ECU,
   }, {
