usb: composite: add bind_deactivated flag to usb_function

2015-07-29T14:59:19Z

This patch introduces 'bind_deactivated' flag in struct usb_function. Functions which don't want to be activated automatically after bind should set this flag, and when they start to be ready to work they should call usb_function_activate(). When USB function sets 'bind_deactivated' flag, initial deactivation counter is incremented automatically, so there is no need to call usb_function_deactivate() in function bind.

usb: composite: fix usb_function_activate/deactivate functions

2015-07-29T14:59:19Z

Using usb_gadget_disconnect to make gadget temporarily invisible to host doesn't provide desired result, because gadget is connected immediately after binding regardless to previous usb_gadget_disconnect() calls. For this reason we use usb_gadget_deactivate() instead of usb_gadget_disconnect() to make it working as expected. Signed-off-by: Robert Baldyga Signed-off-by: Felipe Balbi

usb: gadget: composite: Fix NULL pointer dereference

2015-07-06T17:34:08Z

commit f563d230903210acc ("usb: gadget: composite: add req_match method to usb_function") accesses cdev->config even before set config is invoked causing a NULL pointer dereferencing error while running Lecroy Mass Storage Compliance test. Fix it here by accessing cdev->config only if it is non NULL. Fixes: commit f563d230903210acc ("usb: gadget: composite: add req_match method to usb_function").

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

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: composite: add req_match method to usb_function

2015-03-10T20:33:39Z

Non-standard requests can encode the actual interface number in a non-standard way. For example composite_setup() assumes that it is w_index && 0xFF, but the printer function encodes the interface number in a context-dependet way (either w_index or w_index >> 8). This can lead to such requests being directed to wrong functions. This patch adds req_match() method to usb_function. Its purpose is to verify that a given request can be handled by a given function. If any function within a configuration provides the method and it returns true, then it is assumed that the right function is found. If a function uses req_match(), it should try as hard as possible to determine if the request is meant for it. If no functions in a configuration provide req_match or none of them returns true, then fall back to the usual approach. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi

usb: gadget: composite: don't try standard handling for non-standard requests

2015-03-10T20:33:33Z

If a non-standard request is processed and its parameters just happen to match those of some standard request, the logic of composite_setup() can be fooled, so don't even try any switch cases, just go to the proper place where unknown requests are handled.

usb: gadget: configfs: add suspend/resume

2014-11-03T16:00:59Z

USB gadgets composed with configfs lack suspend and resume methods. This patch uses composite_suspend()/composite_resume() the same way e.g. composite_setup() or composite_disconnect() are used in a configfs-based gadget. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi
