USB: gadget: add USB Audio Gadget driver
Funtions added: - setup all the USB audio class device descriptors - handle class specific setup request - receive data from USB host by ISO transfer - play audio data by ALSA sound card - open and setup playback PCM interface - set default playback PCM parameters - provide playback functions for USB audio driver - provide PCM parameters set/get functions Test on: - Host: Ubuntu 8.10, kernel 2.6.27 - Gadget: EZKIT-BF548 with ASoC AD1980 codec Todo: - add real Mute control code - add real Volume control code - maybe find another way to replace dynamic buffer handling with static buffer allocation - test on Windows system - provide control interface to handle mute/volume control - provide capture interface in the future - test on BF527, other USB device controler and other audio codec Signed-off-by: Bryan Wu <cooloney@kernel.org> Signed-off-by: Mike Frysinger <vapier@gentoo.org> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
