=======
So to specify a complete routing scheme for the msp3400 you will have to
- specify in the 'input' field of the v4l2_routing struct:
+ specify in the 'input' arg of the s_routing function:
1) which tuner input to use
2) which SCART input to use
3) which DSP input to use for each DSP output
- And in the 'output' field of the v4l2_routing struct you specify:
+ And in the 'output' arg of the s_routing function you specify:
1) which SCART input to use for each SCART output
