* usb: gadget: Gadget directory cleanup - group legacy gadgetsAndrzej Pietrasiewicz2014-07-16
| | | | | | | | | | 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: u_ether: convert into moduleAndrzej Pietrasiewicz2013-06-10
| | | | | | | | | | | | | | | 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: remove usb_gadget_controller_number()Sebastian Andrzej Siewior2012-09-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Siewior2012-09-10
| | | | | | | | | | | | | | | | | 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 ethernet gadget: use composite gadget frameworkDavid Brownell2008-07-21
| | | | | | | | | | | | | | | | | | | Building on the previous patches which took code from this driver and pakaged it in more-reusable network "function" components, this patch gets rid of the original code and uses those components instead. As seen with the other gadget driver conversions, the resulting code is much easier to understand and (presumably) work with. In this case that's especially true, since the Ethernet gadget had grown to handle three (!) different Ethernet-over-USB protocols. This modularization should make it much easier to add a fourth option for the newish CDC "Ethernet Emulation Model" (or EEM). Lightly tested, primarily at full speed.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some cleanup to the RNDIS code: - Minor bugfix: rndis_unit() is supposed to put the link into the RNDIS_UNINITIALIZED state, which does not mean "unused". There's a separate method to stop using the link. (Bug doesn't affect anything right now because of how the code is used.) - Reduce coupling between RNDIS code and its user(s), in preparation for updates in that code: * Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device by passing just a void* handle. (Also, remove the unused return value of the notification callback.) * When it needs a copy of net_device stats, just ask for it - Remove unused/untested code backing various never-used OIDs: * RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the relevant docs were unclear, ambguous, and incomplete. Someone with access to the Hidden Gospels (maybe in the EU?) might be able to figure out what this should do. * RNDIS_OPTIONAL_STATS ... as the name suggests, optional. Never implemented in part because not all the semantics were clear. * OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever. - A few small whitespace fixes Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style. There should be no functional changes because of this patch; it's a net source code shrink (because of the dead/unused code removal) and a small object code shrink (a couple hundred bytes on ARMv5).

* [ARM] 5120/1: pxa: correct platform driver names for PXA25x and PXA27x UDC ↵Philipp Zabel2008-07-09
| | | | | | | | | | | | | | | | | | | | | | drivers The pxa2xx_udc.c driver is renamed to pxa25x_udc.c (the platform driver name changes from pxa2xx-udc to pxa25x-udc) and the platform driver name of pxa27x_udc.c is fixed to pxa27x-udc. pxa_device_udc in devices.c is split into pxa25x and pxa27x flavors and the pxa27x_device_udc is enabled in pxa27x.c.

* usb: pxa27x_udc driverRobert Jarzmik2008-05-02
| | | | | | | | | | | | | | | | Adds pxa27x udc driver to support USB peripherals on pxa27x chips. The driver is compatible with: Gadget Zero, the File Storage gadget, and the Ethernet gadget (only in CDC subset mode). The driver can't properly support multiple interfaces, because of hardware bugs without possible workaround. That means no RNDIS support from g_ether, and no CDC ACM support in g_serial.

* USB: gadget section fixesDavid Brownell2008-04-25
| | | | | | | | | | | | Restore some section annotations: they were switched to "__devinit" while they should have been "__init", because of bogus warnings. The warnings are now fixed, so the runtime footprint of various drivers can now shrink a bit. On ARMv5, it's about 600 bytes except for the Ethernet gadget, where it can save a bit more.

* USB: gadget: queue usb USB_CDC_GET_ENCAPSULATED_RESPONSE messageJan Altenberg2008-02-21
| | | | | | | | | | | | | | commit 0cf4f2de0a0f4100795f38ef894d4910678c74f8 introduced a bug, which prevents sending an USB_CDC_GET_ENCAPSULATED_RESPONSE message. This breaks the RNDIS initialization (especially / only Windoze machines dislike this behavior...).
