ALSA: usb-audio: Add mixer support for Pioneer DJ DJM-250MK2
This patch extends support for DJM-250MK2 and allows mapping playback and capture channels to available sources. Configures the card through USB commands.

/*
|
||||
* Pioneer DJ DJM-250MK2 and maybe other DJM models
|
||||
*
|
||||
* For playback, no duplicate mapping should be set.
|
||||
* There are three mixer stereo channels (CH1, CH2, AUX)
|
||||
* and three stereo sources (Playback 1-2, Playback 3-4, Playback 5-6).
|
||||
* Each channel should be mapped just once to one source.
|
||||
* If mapped multiple times, only one source will play on given channel
|
||||
* (sources are not mixed together).
|
||||
*
|
||||
* For recording, duplicate mapping is OK. We will get the same signal multiple times.
|
||||
*
|
||||
* Channels 7-8 are in both directions fixed to FX SEND / FX RETURN.
|
||||
*
|
||||
* See also notes in the quirks-table.h file.
