usb: gadget: add max_speed to usb_composite_driver

2011-07-01T21:27:05Z

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. [ balbi@ti.com : dropped the ifdeffery ] Signed-off-by: Tatyana Brokhman Signed-off-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb gadget: don't save bind callback in struct usb_configuration

2010-10-22T17:21:26Z

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 fixed

2010-08-10T21:35:37Z

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 level

2009-12-11T19:55:15Z

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. Signed-off-by: Laurent Pinchart Cc: David Brownell Signed-off-by: Greg Kroah-Hartman

USB audio gadget: Prefix all macro definitions with UAC_ in linux/usb/audio.h

2009-09-23T13:46:20Z

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. Signed-off-by: Laurent Pinchart Signed-off-by: Greg Kroah-Hartman

USB: gadget: audio: provide correct device id

2009-07-12T22:16:36Z

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. Cc: Bryan Wu Cc: Mike Frysinger Cc: David Brownell Signed-off-by: Greg Kroah-Hartman

USB: gadget: add USB Audio Gadget driver

2009-06-16T04:44:47Z
