usb: udc: store usb_udc pointer in struct usb_gadget

2015-03-19T16:25:46Z

Instead of iterate to find usb_udc according to usb_gadget, this way is easier. Alan Stern suggests this way too: http://marc.info/?l=linux-usb&m=142168496528894&w=2 Acked-by: Alan Stern Signed-off-by: Peter Chen Signed-off-by: Felipe Balbi

usb: gadget: Fix typo fond in Documentation/Docbook/gadget.xml

2015-03-11T15:19:35Z

This patch fix some spelling typo found in gadget.xml. It is because this file is generated from comments in sources, I had to fix comments in the source, instead of xml file itself. Signed-off-by: Masanari Iida Signed-off-by: Felipe Balbi

usb: gadget: introduce is_selfpowered for usb_gadget

2015-01-29T16:32:21Z

Whether the gadget is selfpowerwed or not can be determined by composite core, so we can use a common entry to indicate if the self-powered is supported by gadget, and the related private variable at individual udc driver can be deleted. Signed-off-by: Peter Chen Signed-off-by: Felipe Balbi

usb: gadget: udc: core: prepend udc_attach_driver with usb_

2014-11-03T16:01:16Z

No functional changes, just adding a prefix which should have been there from the start. Signed-off-by: Felipe Balbi

usb: gadget: remove unnecessary 'driver' argument

2014-11-03T16:01:16Z

now that no UDC driver relies on the extra 'driver' argument to ->udc_stop(), we can safely remove it. This commit is based on previous work by Robert Baldyga which can be found at [1]; however that patch turned out to have a high probability of regressing many UDC drivers because of a blind search & replace s/driver/$udc->driver/ which caused the 'driver' argument to stop_activity() to be a valid non-NULL pointer when it should be NULL, thus causing UDCs to mistakenly call gadget driver's ->disconnect() callback.

usb: gadget: Introduce usb_gadget_giveback_request()

2014-09-25T14:58:17Z

All USB peripheral controller drivers call completion routines directly. This patch adds usb_gadget_giveback_request() which will be used instead of direct invocation in the next patch. The goal here is to have a place where common functionality can be added. Signed-off-by: Michal Sojka Acked-by: Felipe Balbi Tested-by: Felipe Balbi Signed-off-by: Greg Kroah-Hartman

usb: gadget: udc-core: add utility for bus reset

2014-09-12T14:12:51Z

The udc driver can notify the udc core that bus reset occurs by calling this utility, the core will notify gadget driver this information and update gadget state accordingly. Signed-off-by: Peter Chen Signed-off-by: Felipe Balbi

usb: gadget: add reset API at usb_gadget_driver

2014-09-09T14:58:09Z

Adding reset API for UDC bus reset handler is useful for below two issues. Current disconnect API at usb_gadget_driver is also invoked at udc's bus reset handler, but the document says it is invoked when the host is disconnected. Besides, we may expect the gadget_driver to do different things for host sends bus reset and host disconnects gadget, eg, we may not want to flush dirty page for mass storage at bus reset, and want to do it at disconnection.

usb: gadget: document a usb_ep_dequeue() requirement

2014-08-21T21:13:52Z

Document the requirement that the request be dequeued and its completion routine called before usb_ep_dequeue() returns. Also fix some capitalization issues in the existing text. Signed-off-by: Paul Zimmerman Acked-by: Alan Stern Signed-off-by: Felipe Balbi
