* usb: gadget: Gadget directory cleanup - group legacy gadgetsAndrzej Pietrasiewicz2014-07-161-211/+0
| | | | | | | | | | The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the legacy gadgets (i.e. those not using configfs) into a separate directory. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: gadget: Convert drivers to use module_usb_composite_driver()Tobias Klauser2014-07-101-12/+2
| | | | | | | | | Use the module_usb_composite_driver() macro where applicable to eliminate the module_init/module_exit boilerplate in USB gadget composite drivers. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: Felipe Balbi <balbi@ti.com>

* usb: gadget: f_ncm: convert to new function interface with backward ↵Andrzej Pietrasiewicz2013-06-101-0/+1
| | | | | | | | | | | | | | | | | | | compatibility Converting ncm to the new function interface requires converting the USB ncm's function code and its users. This patch converts the f_ncm.c to the new function interface. The file is now compiled into a separate usb_f_ncm.ko module. The old function interface is provided by means of a preprocessor conditional directives. After all users are converted, the old interface can be removed.

* usb: gadget: u_ether: convert into moduleAndrzej Pietrasiewicz2013-06-101-4/+6
| | | | | | | | | | | | | | | u_ether.c has been #include'd by all gadgets which implement USB Ethernet functions. In order to add configfs support, the f_ecm.c, f_eem.c, f_ncm.c, f_subset.c, f_rndis.c need to be converted into modules and must not be #include'd. Consequently, the u_ether.c needs to be a module too, in a manner similar to u_serial.c. The resulting module should not take any parameters, so they are pushed to the current users of it, that is ether.c, g_ffs.c, multi.c, ncm.c, nokia.c.

* usb: gadget: move the global the_dev variable to their usersSebastian Andrzej Siewior2013-04-031-6/+7
| | | | | | | | | | | the u_ether.c file has a global variable named the_dev which keeps a pointer to the network device after it has been created via gether_setup_name(). It is only used internally by u_ether. This patches moves the variable to its users and passes it via the port.ioport where it is saved later anyway.

* usb: gadget: remove usb_gadget_controller_number()Sebastian Andrzej Siewior2012-09-101-17/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The bcdDevice field is defined as |Device release number in binary-coded decimal in the USB 2.0 specification. We use this field to distinguish the UDCs from each other. In theory this could be used on the host side to apply certain quirks if the "special" UDC in combination with this gadget is used. This hasn't been done as far as I am aware. In practice it would be better to fix the UDC driver before shipping since a later release might not need this quirk anymore. There are some driver in tree (on the host side) which use the bcdDevice field to figure out special workarounds for a given firmware revision. This seems to make sense. Therefore this patch converts all gadgets (except a few) to use the kernel version instead a random 2 or 3 plus the UDC number. The few that don't report kernel's version are: - webcam This one reports always a version 0x10 so allow it to do so in future. - nokia This one reports always 0x211. The comment says that this gadget works only if the UDC supports altsettings so I added a check for this. - serial This one reports 0x2400 + UDC number. Since the gadget version is 2.4 this could make sense. Therefore bcdDevice is 0x2400 here. I also remove various gadget_is_<name> macros which are unused. The remaining few macros should be moved to feature / bug bitfield.

* usb: gadget: Provide a default implementation of default manufacturer stringSebastian Andrzej Siewior2012-09-101-11/+1
| | | | | | | | | | | | | | | | | Some gadgets provide custom entry here. Some may override it with an etntry that is also created by composite if there was no value sumbitted at all. This patch removes all "custom manufacturer" strings which are the same as these which are created by composite. Then it moves the creation of the default manufacturer string to usb_composite_overwrite_options() in case no command line argument has been used and the entry is still an empty string. By doing this we get rid of the global variable "composite_manufacturer" in composite.

* usb: gadget: make sure each gadget is using same index for Product, Serial,…Sebastian Andrzej Siewior2012-09-101-8/+5
| | | | | | | | | | | | | | The index in usb_string array is defined by the gadget. The gadget can choose which index entry it assigns for the serial number and which the product name. The gadget has just to ensure that the descriptor contains the proper string id which is assigned by composite. If the composite layer knows the index of the "default" information which will be overwritten by module parameters, it can be used later to overwrite it.

* usb: gadget: move bind() callback back to struct usb_composite_driverSebastian Andrzej Siewior2012-09-101-1/+2
| | | | | | | | | | | This partly reverts 07a18bd7 ("usb gadget: don't save bind callback in struct usb_composite_driver") and fixes new drivers.

* usb: gadget: push all usb_composite_driver structs into __refdataSebastian Andrzej Siewior2012-09-101-1/+1
| | | | | | | | | | | | | | As it turns out, Sam's comment was better than I initially assumed. This patch pushes as struct usb_composite_driver data structures into __refdata section to avoid a section missmatch report from modpost because the ->bind() can be marked __init. The only downside is that modpost does not check between ->bind() and other member. However, it is temporary.
