2013-12-17usb: gadget: add "maxpacket_limit" field to struct usb_epRobert Baldyga30-61/+92
This patch adds "maxpacket_limit" to struct usb_ep. This field contains maximum value of maxpacket supported by driver, and is set in driver probe. This value should be used by autoconfig() function, because value of field "maxpacket" is set to value from endpoint descriptor when endpoint becomes enabled. So when autoconfig() function will be called again for this endpoint, "maxpacket" value will contain wMaxPacketSize from descriptior instead of maximum packet size for this endpoint. For this reason this patch adds new field "maxpacket_limit" which contains value of maximum packet size (which defines maximum endpoint capabilities). This value is used in ep_matches() function used by autoconfig(). Value of "maxpacket_limit" should be set in UDC driver probe function, using usb_ep_set_maxpacket_limit() function, defined in gadget.h. This function set choosen value to both "maxpacket_limit" and "maxpacket" fields. This patch modifies UDC drivers by adding support for maxpacket_limit.

2013-12-12usb: gadget: FunctionFS: Remove VLAIS usage from gadget codeAndrzej Pietrasiewicz1-40/+76
The use of variable length arrays in structs (VLAIS) in the Linux Kernel code precludes the use of compilers which don't implement VLAIS (for instance the Clang compiler). This alternate patch calculates offsets into the kmalloc-ed memory buffer using macros. The previous patch required multiple kmalloc and kfree calls. This version uses "group" vs "struct" since it really is not a struct and is essentially a group of VLA in a common allocated block. This version also fixes the issues pointed out by Andrzej Pietrasiewicz and Michal Nazarewicz.

2013-12-12usb: gadget: configfs: allow setting function instance's nameAndrzej Pietrasiewicz2-0/+9
USB function's configfs config group is created in a generic way in usb/gadget/configfs.c:function_make(), which in turn delegates actual allocation and setup of the USB function instance to a particular implementation, e.g. in f_acm.c. The said implementation does its job in a parameter-less function e.g. acm_alloc_instance(), which results in creating an unnamed config group, whose name is set later in function_make(). function_make() creates the name by parsing a string of the form: <function name>.<instance name> which comes from userspace as a parameter to mkdir invocation. Up to now only <function name> has been used, while <instance name> has been ignored. This patch adds a set_inst_name() operation to struct usb_function_instance which allows passing the <instance name> from function_make() so that it is not ignored. It is entirely up to the implementor of set_inst_name() what to do with the <instance name>. In a typical case, the struct usb_function_instance is embedded in a larger struct which is retrieved in set_inst_name() with container_of(), and the larger struct contains a field to store the <instance name>.

This patch adds flushing TX FIFO in kill_all_requests() function in dedicated-fifo mode. It's because when requests are killed (when endpoint is disabled or in case of device reset/disconnection) in FIFO can stay some unsent data. In the worst case FIFO can stay full, and then if endpoint will be back enabled, sending new data will be impossible.

2013-11-26usb: gadget: composite: redirect setup requestsAndrzej Pietrasiewicz1-1/+15
If there are setup requests not directed to an endpont or an interface, current config's setup() has been attempted so far. This patch, in case the above fails, adds code which tries the setup() of configuration's function if there is only one function in the configuration. This behavior is required to provide equivalent of gadget zero with configfs. The gadget zero has a "config driver" for sourcesink, but all it does is delegating the request to the function proper. So when the equivalent gadget is set up with configfs it needs to handle requests directed to "config driver", but with configfs it is not possible to specify "config drivers".
