* usb: gadget: add max_speed to usb_composite_driverTatyana Brokhman2011-07-011-0/+1
| | | | | | | | | | | | | | | This field is used by the Gadget drivers to specify the maximum speed they support, meaning: the maximum speed they can provide descriptors for. The driver speed will be set in consideration of this value.

* usb gadget: don't save bind callback in struct usb_configurationUwe Kleine-König2010-10-221-2/+1
| | | | | | | | | | | | | The bind function is most of the time only called at init time so there is no need to save a pointer to it in the configuration structure. This fixes many section mismatches reported by modpost.

* USB: gadget: section mismatch warning fixedMichal Nazarewicz2010-08-101-2/+2
| | | | | | | | | | | | | In may gadgets bind and bind like functions were in a init section as they were only run during initialisation. However, being callback functions they were referenced from structures in “normal” sections. Changing the tag from “__init” to “__ref” fixes the warnings.

* USB audio gadget: handle endpoint control requests at the function levelLaurent Pinchart2009-12-111-115/+0
| | | | | | | | | | | Now that control requests targeted at an endpoint can be handled at the function level, move the UAC-specific control request handling code from the audio gadget driver to the audio function driver.

* USB audio gadget: Prefix all macro definitions with UAC_ in linux/usb/audio.hLaurent Pinchart2009-09-231-12/+12
| | | | | | | | | | linux/usb/audio.h is a public header file that includes definitions exported to userspace. To avoid namespace clashes, prefix all macro definitions with UAC_. Existing macros and structures prefixed with USB_AC_ and USB_AS_ are renamed for consistency.

* USB: gadget: audio: provide correct device idGreg Kroah-Hartman2009-07-121-3/+3
| | | | | | | | | | | The audio gadget driver should use a "Linux" device id, instead of relying on NetChip's vendor id. So provide one out of our reserved namespace.

* USB: gadget: add USB Audio Gadget driverBryan Wu2009-06-151-0/+302
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>
