+/* msp3400 routing
+ ===============
+
+ The msp3400 has a complicated routing scheme with many possible
+ combinations. The details are all in the datasheets but I will try
+ to give a short description here.
+
+ Inputs
+ ======
+
+ There are 1) tuner inputs, 2) I2S inputs, 3) SCART inputs. You will have
+ to select which tuner input to use and which SCART input to use. The
+ selected tuner input, the selected SCART input and all I2S inputs go to
+ the DSP (the tuner input first goes through the demodulator).
+
+ The DSP handles things like volume, bass/treble, balance, and some chips
+ have support for surround sound. It has several outputs: MAIN, AUX, I2S
+ and SCART1/2. Each output can select which DSP input to use. So the MAIN
+ output can select the tuner input while at the same time the SCART1 output
+ uses the I2S input.
+
+ Outputs
+ =======
+
+ Most DSP outputs are also the outputs of the msp3400. However, the SCART
+ outputs of the msp3400 can select which input to use: either the SCART1 or
+ SCART2 output from the DSP, or the msp3400 SCART inputs, thus completely
+ bypassing the DSP.
+
+ Summary
+ =======
+
+ So to specify a complete routing scheme for the msp3400 you will have to
+ specify in the 'input' field of the v4l2_routing struct:
+
+ 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:
+
+ 1) which SCART input to use for each SCART output
+
+ Depending on how the msp is wired to the other components you can
+ ignore or mute certain inputs or outputs.
+
+ Also, depending on the msp version only a subset of the inputs or
+ outputs may be present. At the end of this header some tables are
+ added containing a list of what is available for each msp version.
+ */
+
+/* Inputs to the DSP unit: two independent selections have to be made:
+ 1) the tuner (SIF) input
+ 2) the SCART input
+ Bits 0-2 are used for the SCART input select, bit 3 is used for the tuner
+ input, bits 4-7 are reserved.

+/* The msp has up to 5 DSP outputs, each output can independently select
+ a DSP input.
+
+ The DSP outputs are: loudspeaker output (aka MAIN), headphones output
+ (aka AUX), SCART1 DA output, SCART2 DA output and an I2S output.
+ There also is a quasi-peak detector output, but that is not used by
+ this driver and is set to the same input as the loudspeaker output.
+ Not all outputs are supported by all msp models. Setting the input
+ of an unsupported output will be ignored by the driver.
+
+ There are up to 16 DSP inputs to choose from, so each output is
+ assigned 4 bits.
+
+ Note: the 44x8G can mix two inputs and feed the result back to the
+ DSP. This is currently not implemented. Also not implemented is the
+ multi-channel capable I2S3 input of the 44x0G. If someone can demonstrate
+ a need for one of those features then additional support can be added. */
