This patch pushes the iManufacturer module argument from composite into each gadget. Once the user uses the module paramter, the string is overwritten with the final value. Acked-by:

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. Acked-by:

This patch moves the module options idVendor, idProduct and bcdDevice from composite.c into each gadgets. This ensures compatibility with current gadgets and removes the global variable which brings me step closer towards composite.c in libcomposite Acked-by:

After I moved the function from the header file to the c file I see: | $ size drivers/usb/gadget/gadget_chips.o | text data bss dec hex filename | 1048 0 0 1048 418 drivers/usb/gadget/gadget_chips.o That is almost a KiB which is removed from each user. As Felipe pointed out, the function / usage is very dumb actually. This is used for the following reasons: - epautoconf ep hint (could provide a per-gadget callback) - miss-features. currently the missing altsetting on pxa's and something ZLP related on musbhdrc (looks like an optimisation which could be implemented in musb itself if it is correct) - unique BCD accross all UDCs. Not sure how important this is. Acked-by:

I have no idea what I've been thinking while I was doing this in the first place. Now the strings are initialized properly and reported by lsusb. Cc: stable@vger.kernel.org # v3.5 Acked-by:

This was broken in 2e87edf4 ("usb: gadget: make g_printer use composite"). The USB-strings were not setup properly and were not used. No function was added which results in an empty USB config. While fixing this, the interface number is now auto generated and not hard coded to 0. Cc: stable@vger.kernel.org # v3.5 Acked-by:

Using usb_string_ids_tab() instead multiple calls of usb_string_id() seems to be handy. It also allows to add string without many checks. Acked-by:

This is a partly revert of 4fffd6e5 ("usb: gadget: composite: make module parameters accessible at runtime"). It is not possible to change the VID or other property for a gadget right now. This change has been made for Anrdoid gadget which has this functionality in its copy of the file. This function is executed currently only once and most caller in tree are __init. Acked-by:

there is no read user of bufsiz, its content is available via USB_COMP_EP0_BUFSIZ. Remove it. Acked-by:

Sebastian Andrzej Siewior authored
This patch moves USB_BUFSIZ into global header file as USB_COMP_EP0_BUFSIZ. There is currently only one user (f_sourcesink) besides composite which need it. Ideally f_sourcesink would have its own ep0 buffer. Lets keep it that way it was for now. Acked-by:

Sebastian Andrzej Siewior authored
epautoconf has two global variables which count the endpoint number of last assigned endpoint. This patch removes the global variable and keeps it as per (UDC) gadget. While here, the ifdef is removed and now the in and outpoint are enumerated unconditionally. The dwc3 for instance supports 32 endpoints in total. Acked-by:

This patch removes the global variable composite in composite.c. The private data which was saved there is now passed via an additional argument to the bind() function in struct usb_gadget_driver. Only the "old-style" UDC drivers have to be touched here, new style are doing it right because this change is made in udc-core. Acked-by:

This Android gadget includes a bunch of .c files. Fixing normal gadgets is not the real problem but this gadget is not always fixable since the problem here are fundumential / design. *I* wanted to get this removed but other people want to keep it even though there were reports that Android itself is not using it. Some poeple think that it is better to have this instead of nothing and other argue that they need sdb and mass storage gadget. The sdb function is not provided by ccg so I don't see the point of this. I don't see any logical reasoning behind it and I decided that it is time for retreat. This patch brings all dependencies of ccg into staging so I can do whatever I want in drivers/usb/gadget without breaking ccg. Cc: devel@driverdev.osuosl.org Signed-off-by:

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. Cc: Sam Ravnborg <sam@ravnborg.org> Acked-by:

It was moved to be an argument in 07a18bd7 ("usb gadget: don't save bind callback in struct usb_composite_driver"). The reason was to avoid the section missmatch. The warning was shown because ->bind is marked as __init becuase it is a one time init. The warning can be also suppresed by whitelisting the variable i.e. rename it to lets say _probe. Acked-by:

Driver for the "USB20D" / "USBD" block on BCM6328, BCM6368, BCM6816, BCM6362, BCM3383, and others. The hardware block was designed to support networking applications (direct connection of a home router to a PC), and the endpoint configuration is fixed.

This commit removes USB_GADGET_DUALSPEED and USB_GADGET_SUPERSPEED Kconfig options. Since now kernel allows many UDC drivers to be compiled, those options may turn to no longer be valid. For instance, if someone decides to build UDC that supports super speed and UDC that supports high speed only, the latter will be "assumed" to support super speed since USB_GADGET_SUPERSPEED will be selected by the former. The test of whether CONFIG_USB_GADGET_*SPEED was defined was just an optimisation which removed otherwise dead code (ie. if UDC is not dual speed, there is no need to handle cases that can happen if speed is high). This commit removes those checks. Signed-off-by:

The lpc32xx_udc driver supported only one controller by defining a global static struct for it. This patch enables multiple instances of the controller by dynamic allocation of the struct at probe(). A static struct is kept as a template on initialization since it does some complex preset, reflecting fixed hardware endpoint structure. Signed-off-by:
