usb: gadget: Gadget directory cleanup - group legacy gadgets

2014-07-16T17:14:05+00:00

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 Signed-off-by: Felipe Balbi

usb: gadget: allocate & giveback serial ports instead hard code them

2013-01-21T18:52:43+00:00

This patch removes gserial_setup() and gserial_cleanup() and adds gserial_alloc_line() and gserial_free_line() to replace them. The initial setup of u_serial happens now on module load time. A maximum of four TTY ports can be requested which is the current limit. In theory we could extend this limit, the hard limit is the number of available endpoints. alloc_tty_driver() is now called at module init time with the max available ports. The per-line footprint here is on 32bit is 3 * size of pointer + 60 bytes (for cdevs). The remaining memory (struct gs_port) is allocated once a port is requested. With this change it is possible to load g_multi and g_serial at the same time. GS0 receives the module that is loaded first, GS1 is received by the next module and so on. With the configfs interface the port number can be exported and the device node is more predictable. Nothing changes for g_serial and friends as long as one module is used.

usb: gadget: u_serial: convert into a module

2013-01-21T18:52:42+00:00

Every user of u_serial has now to select the U_SERIAL symbol instead of including the file. There is one limition with this: ports and and gs_tty_driver are global variables in u_serial. Since all users share them, there can be only one user loaded at a time i.e. either g_serial or g_nokia. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: libcomposite: add epautoconf.c to libcomposite

2012-09-10T12:37:51+00:00

This patch adds epautoconf.c into libcomposite and updates all gadgets. Acked-by: Michal Nazarewicz Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: remove global variable composite in composite.c

2012-09-10T12:35:41+00:00

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.

usb: gadget: move bind() callback back to struct usb_gadget_driver

2012-09-10T12:35:16+00:00

This partly reverts 07a18bd7 ("usb gadget: don't save bind callback in struct usb_composite_driver") and fixes new drivers. The section missmatch problems was solved by whitelisting bind callback in modpost. Acked-by: Michal Nazarewicz Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: push all usb_composite_driver structs into __refdata

2012-09-10T12:34:24+00:00

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.

usb: gadget: rename usb_gadget_driver::speed to max_speed

2011-12-12T09:45:12+00:00

This commit renames the “speed” field of the usb_gadget_driver structure to “max_speed”. This is so that to make it more apparent that the field represents the maximum speed gadget driver can support. This also make the field look more like fields with the same name in usb_gadget and usb_composite_driver structures. All of those represent the *maximal* speed given entity supports. After this commit, there are the following fields in various structures: * usb_gadget::speed - the current connection speed, * usb_gadget::max_speed - maximal speed UDC supports, * usb_gadget_driver::max_speed - maximal speed gadget driver supports, and * usb_composite_driver::max_speed - maximal speed composite gadget supports.

usb: Add module.h to drivers/usb consumers who really use it.

2011-10-31T23:31:25+00:00

The situation up to this point meant that module.h was pretty much everywhere, regardless of whether you asked for it or not. We are fixing that, so give the USB folks who want it an actual include of it. Signed-off-by: Paul Gortmaker
