usb: gadget: always update HS/SS descriptors and create a copy of them

2012-10-31T13:09:44Z

HS and SS descriptors are staticaly created. They are updated during the bind process with the endpoint address, string id or interface numbers. After that, the descriptor chain is linked to struct usb_function which is used by composite in order to serve the GET_DESCRIPTOR requests, number of available configs and so on. There is no need to assign the HS descriptor only if the UDC supports HS speed because composite won't report those to the host if HS support has not been reached. The same reasoning is valid for SS. This patch makes sure each function updates HS/SS descriptors unconditionally and uses the newly introduced helper function to create a copy the descriptors for the speed which is supported by the UDC. While at that, also rename f->descriptors to f->fs_descriptors in order to make it more explicit what that means.

usb: gadget: add isochronous support to gadget zero

2012-05-04T12:53:08Z

Add two isochronous endpoints to the gadget zero source/sink function. They are enabled by selecting alternate interface 1, so by default they are not enabled. Module parameters for setting all the isoc endpoint characteristics are also provided. Signed-off-by: Pratyush Anand Signed-off-by: Paul Zimmerman Signed-off-by: Felipe Balbi

usb: gadget: zero: fix bug in loopback autoresume handling

2012-01-30T09:10:20Z

ab943a2e125b (USB: gadget: gadget zero uses new suspend/resume hooks) introduced a copy-paste error where f_loopback.c writes to a variable declared in f_sourcesink.c. This prevents one from creating gadgets that only have a loopback function. Cc: stable Signed-off-by: Timo Juhani Lindfors Signed-off-by: Felipe Balbi

usb: gadget: zero: add superspeed support

2011-07-08T10:57:54Z

This patch adds SuperSpeed descriptors to the g_zero gadget. The SuperSpeed descriptors were added both for f_soursesink and f_loopback function drivers. Signed-off-by: Tatyana Brokhman Signed-off-by: Amit Blay Signed-off-by: Felipe Balbi

usb: gadget: use config_ep_by_speed() instead of ep_choose()

usb: gadget: add usb_endpoint_descriptor to struct usb_ep

2011-06-28T18:14:36Z

Change usb_ep_enable() prototype to use endpoint descriptor from usb_ep. This optimization spares the FDs from saving the endpoint chosen descriptor. This optimization is not full though. To fully exploit this change, one needs to update all the UDCs as well since in the current implementation each of them saves the endpoint descriptor in it's internal (and extended) endpoint structure.

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.
