* usb, g_dnl: generalize DFU detach functionsRob Herring2014-12-18-0/+17
| | | | | | | | | In order to add detach functions for fastboot, make the DFU detach related functions common so they can be shared. Signed-off-by: Rob Herring <robh@kernel.org> Tested-by: Lukasz Majewski <l.majewski@samsung.com> [TestHW: Exynos4412-Trats2]
* USB: gadget: save driver name before registering itStephen Warren2014-05-05-1/+2
| | | | | | | | | | | | | | | g_dnl_register() currently first attempts to register a composite driver by name, and then saves the driver name once it's registered. Internally to the registration code, g_dnl_do_config() is called and attempts to compare the composite device's name with the list of known device names. This fails since the composite device's name has not yet been stored. This means that the first time "ums 0 0" is run, it fails, but subsequent attempts succeed. Re-order the name-saving and registration code to solve this. Fixes: e5b834e07f51 ("USB: gadget: added a saner gadget downloader registration API") Signed-off-by: Stephen Warren <swarren@nvidia.com>

| | | | | | | | | | Preprocessor definitions and hardcoded implementation selection in g_dnl core were replaced by a linker list made of (usb_function_name, bind_callback) pairs.

* usb: dfu: fix boards wo USB cable detectionMateusz Zalega2014-05-05-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | Former usb_cable_connected() patch broke compilation of boards which do not support this feature. I've renamed usb_cable_connected() to g_dnl_usb_cable_connected() and added its default implementation to gadget downloader driver code. There's only one driver of this kind and it's unlikely there'll be another, so there's no point in keeping it in /common. Previously this function was declared in usb.h. I've moved it, since it's more appropriate to keep it in g_dnl.h - usb.h seems to be intended for USB host implementation. Existing code, confronted with default -EOPNOTSUPP return value, continues as if the cable was connected. CONFIG_USB_CABLE_CHECK was removed.

| | | | | | | | | | | | | | add the possibility to set the iSerialNumber board specific. Default value for iSerialNumber is 0x0. This value can changed board specific through the new function g_dnl_set_serialnumber() which must be called from the board specific function g_dnl_bind_fixup().

| | | | | | | | | | | | The download gadget code and DFU function lacks of proper declarations for the case when a target board wants to use only one of available usb functions. Moreover the relevant declarations have been moved to consistent localization (like <dfu.h>). Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de>
* usb:gadget:Remove redundant #includes for USB composite gadget and its functionsLukasz Majewski2013-09-24-1/+0

| | | | | | | | | | | | | | | (f_mass_storage) The mass storage composite function is now compiled in only when CONFIG_USB_GADGET_MASS_STORAGE is defined. Such change provides binary size reduction for boards which use USB download gadget (like am335x_evm) with DFU, but don't use UMS. For example at am335x_evm board reduction is more than 2KiB for text and around 120B for data. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Cc: Marek Vasut <marex@denx.de>
