recent changes to gadget framework have exposed a flaw in nokia.c where it uses f_ecm.c but it wasn't including it like other gadget drivers. This is a temporary patch until all other function drivers are converted to new API where each function driver becomes a module and binding is done through configfs. Solves a linking error when building g_nokia.ko Signed-off-by: -

Converting f_obex to the new function interface requires converting the f_obex's function code and its users. This patch converts the f_obex.c to the new function interface. The file is now compiled into a separate usb_f_obex.ko module. The old function interface is provided by means of preprocessor conditional directives. After all users are converted, the old interface can be removed. Signed-off-by:

In order to convert to configfs the USB functions need to be converted to the new interface from Sebastian, which also requires turning them into separate modules. Some of these modules will consist of just one object file, e.g. f_ncm.o. But some of the modules will eventually consist of more than one object file, e.g. for mass storage there will be f_mass_storage.o and storage_common.o. The resulting module cannot be called f_mass_storage.ko due to cyclic dependency. This patch introduces a naming scheme for the said resulting modules: usb_f_xxxxxx.ko e.g. usb_f_mass_storage.ko, usb_f_ss_lb.ko, usb_f_rndis.ko etc. Signed-off-by:

The name of available UDCs can be obtained from /sys/class/udc/ v4…v5 - string rework. This will add a strings folder incl. language code like strings/409/manufacturer as suggested by Alan. - rebased ontop reworked functions.c which has usb_function_instance which is used prior after "mkdir acm.instance" and can be directly used for configuration via configfs. v3…v4 - moved functions from the root folde down to the gadget as suggested by Michał - configs have now their own configs folder as suggested by Michał. The folder is still name.bConfigurationValue where name becomes the sConfiguration. Is this usefull should we just stilc configs/bConfigurationValue/ ? - added configfs support to the ACM function. The port_num attribute is exported by f_acm. An argument has been added to the USB alloc function to distinguish between "old" (use facm_configure() to configure and configfs interface (expose a config_node). The port_num is currently a dumb counter. It will require some function re-work to make it work. scheduled for v5: - sym linking function into config. v2…v3 - replaced one ifndef by ifdef as suggested by Micahał - strstr()/strchr() function_make as suggested by Micahł - replace [iSerialNumber|iProduct|iManufacturer] with [sSerialNumber|sProduct|sManufacturer] as suggested by Alan - added creation of config descriptors v1…v2 - moved gadgets from configfs' root directory into /udcs/ within our "usb_gadget" folder. Requested by Andrzej & Michał - use a dot as a delimiter between function's name and its instance's name as suggested by Michał - renamed all config_item_type, configfs_group_operations, make_group, drop_item as suggested by suggested by Andrzej to remain consisten within this file and within other configfs users - Since configfs.c and functions.c are now part of the udc-core module, the module itself is now called udc. Also added a tiny ifdef around init code becuase udc-core is subsys init and this is too early for configfs in the built-in case. In the module case, we can only have one init function.

It possible to allocate the tty port number within the "instance" structure of the function and there is no need to expose this information within the gadget and therefore it is removed here.

MUSB controller cannot work in DMA mode with misaligned buffers, switching in PIO mode. HCD core has hooks that allow to override the default DMA mapping and unmapping routines for host controllers that have special DMA requirements, such as alignment constraints. It is observed that work in PIO mode is slow and it's better to align buffers properly before passing them to MUSB This increased throughput 80->120 MBits/s over musb@omap4 with USB Gigabit Ethernet adapter attached.
