-20. UAC1 function (virtual ALSA card, using u_audio API)
-=================
-
-The function is provided by usb_f_uac1.ko module.
-It will create a virtual ALSA card and the audio streams are simply
-sinked to and sourced from it.
-
-Function-specific configfs interface
-------------------------------------
-
-The function name to use when creating the function directory is "uac1".
-The uac1 function provides these attributes in its function directory:
-
-	c_chmask - capture channel mask
-	c_srate - capture sampling rate
-	c_ssize - capture sample size (bytes)
-	p_chmask - playback channel mask
-	p_srate - playback sampling rate
-	p_ssize - playback sample size (bytes)
-	req_number - the number of pre-allocated request for both capture
-		     and playback
-
-The attributes have sane default values.
-
-Testing the UAC1 function
--------------------------
-
-device: run the gadget
-host: aplay -l # should list our USB Audio Gadget
-
-This function does not require real hardware support, it just
-sends a stream of audio data to/from the host. In order to
-actually hear something at the device side, a command similar
-to this must be used at the device side:
-
-$ arecord -f dat -t wav -D hw:2,0 | aplay -D hw:0,0 &
-
-e.g.:
-
-$ arecord -f dat -t wav -D hw:CARD=UAC1Gadget,DEV=0 | \
-aplay -D default:CARD=OdroidU3
