2008-07-30USB: m66592-udc: Fix up dev_set_name() badness.Paul Mundt
Commit 0031a06e2f07ab0d1bc98c31dbb6801f95f4bf01 converted all of the USB drivers to use dev_set_name(), though there was a typo on the m66592-udc conversion that handed off the wrong pointer (we want the struct device here obviously, not the struct usb_gadget).

2008-07-25Rename WARN() to WARNING() to clear the namespaceArjan van de Ven
We want to use WARN() as a variant of WARN_ON(), however a few drivers are using WARN() internally. This patch renames these to WARNING() to avoid the namespace clash. A few cases were defining but not using the thing, for those cases I just deleted the definition.

2008-07-21usb ethernet gadget: use composite gadget frameworkDavid Brownell
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.

2008-07-21usb gadget: new "CDC Composite" gadget driverDavid Brownell
This is a simple example of a composite gadget, combining two Communications Class Device (CDC) functions: ECM and ACM. This provides a clear example of how the composite gadget framework is intended to work. It's surprising that MS-Windows (or at least, XP and previous) won't "just work" with something this simple...

But many full speed controllers don't have enough endpoints, or (as with the PXA controllers) don't support altsettings. Lightly tested.

2008-07-21usb ethernet gadget: split out network coreDavid Brownell
Abstract the peripheral side Ethernet-over-USB link layer code from the all-in-one Ethernet gadget driver into a component that can be called by various functions, so the various flavors can be split apart and selectively reused. A notable difference from the approach taken with the serial link layer code (beyond talking to NET not TTY) is that because of the initialization requirements, this only supports one network link. (And one set of Ethernet link addresses.) That is, each configuration may have only one instance of a network function. This doesn't change behavior; the current code has that same restriction. If you want multiple logical links, that can easily be done using network layer tools.

2008-07-21usb gadget: RNDIS cleanupsDavid Brownell
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).

2008-07-21usb gadget serial: split out CDC ACM functionDavid Brownell
Split out CDC ACM parts of "gadget serial" to a "function driver". Some key structural differences from the previous ACM support, shared with with the generic serial function (next patch): - As a function driver, it can be combined with other functions. One gadget configuration could offer both serial and network links, as an example. - One serial port can be exposed in multiple configurations; the /dev/ttyGS0 node could be exposed regardless of which config the host selected. - One configuration can expose multiple serial ports, such as ttyGS0, ttyGS1, ttyGS2, and ttyGS3. This code should be a lot easier to understand than the previous all-in-one-big-file version of the driver.

2008-07-21usb gadget zero: use composite gadget frameworkDavid Brownell
Update Gadget Zero to use the more modular versions of the loopback and source/sink configuration drivers which build on the new gadget framework code. The core code is a LOT simpler, and it should be much easier now to understand how the parts fit together. The conversion is an overall source shrink in terms of this gadget, since it uses more midlayer support. However, it's an overall increase in object size because there's less sharing between the two configurations (improves code clarity) and because the midlayer is a bit more functional than this driver actually needs.

It doesn't yet pull the original code out of gadget zero or update how that driver is built. Neither this, nor its sibling "loopback" configuration, is a function driver that can be combined with other functions. (The host "usbtest" driver wouldn't know how to deal with that!)

2008-07-21usb gadget: composite gadget coreDavid Brownell
Add <linux/usb/composite.h> interfaces for composite gadget drivers, and basic implementation support behind it: - struct usb_function ... groups one or more interfaces into a function managed as one unit within a configuration, to which it's added by usb_add_function(). - struct usb_configuration ... groups one or more such functions into a configuration managed as one unit by a driver, to which it's added by usb_add_config(). These operate at either high or full/low speeds and at a given bMaxPower. - struct usb_composite_driver ... groups one or more such configurations into a gadget driver, which may be registered or unregistered. - struct usb_composite_dev ... a usb_composite_driver manages this; it wraps the usb_gadget exposed by the controller driver. This also includes some basic kerneldoc. How to use it (the short version): provide a usb_composite_driver with a bind() that calls usb_add_config() for each of the needed configurations. The configurations in turn have bind() calls, which will usb_add_function() for each function required. Each function's bind() allocates resources needed to perform its tasks, like endpoints; sometimes configurations will allocate resources too. Separate patches will convert most gadget drivers to this infrastructure. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2008-07-21usb gadget: descriptor copying supportDavid Brownell
Define three new descriptor manipulation utilities, for use when setting up functions that may have multiple instances: usb_copy_descriptors() to copy a vector of descriptors usb_free_descriptors() to free the copy usb_find_endpoint() to find a copied version These will be used as follows. Functions will continue to have static tables of descriptors they update, now used as __initdata templates. When a function creates a new instance, it patches those tables with relevant interface and string IDs, plus endpoint assignments. Then it copies those morphed descriptors, associates the copies with the new function instance, and records the endpoint descriptors to use when activating the endpoints. When initialization is done, only the copies remain in memory. The copies are freed on driver removal. This ensures that each instance has descriptors which hold the right instance-specific data. Two instances in the same configuration will obviously never share the same interface IDs or use the same endpoints. Instances in different configurations won't do so either, which means this is slightly less memory-efficient in some cases. This also includes a bugfix to the epautoconf code that shows up with this usage model. It must replace the previous endpoint number when updating the template descriptors, not just mask in a few more bits.

2008-07-21usb gadget: use new serial coreDavid Brownell
Teach "gadget serial" to use the new abstracted (and bugfixed) TTY glue, and remove all the orignal tangled-up code. Update the documentation accordingly. This is a net object code shrink and cleanup; it should make it a lot easier to see how the TTY glue should accomodate updates to the TTY layer, be bugfixed, etc. Notable behavior changes include: it can now support getty even when there's no USB connection; it fits properly into the mdev/udev world; and RX handling is better (throttling works, and low latency). Configurations with scripts setting up the /dev/ttygserial device node (with "experimental" major number) may want to change that to be a symlink pointing to the /dev/ttyGS0 file, as a migration aid; else, just switch entirely over to mdev/udev.

2008-07-21usb gadget: split out serial coreDavid Brownell
This abstracts the "gadget serial" driver TTY glue into a separate component, cleaning it up and disentangling it from connection state. It also changed some behaviors for the better: - Stops using "experimental" major #127, and switches over to having the TTY layer allocate the dev_t numbers. - Provides /sys/class/tty/ttyGS* nodes, thus mdev/udev support. (Note "mdev" hotplug bug in Busybox v1.7.2: /dev/ttyGS0 will be a *block* device without CONFIG_SYSFS_DEPRECATED_V2.) - The tty nodes no longer reject opens when there's no host. Now they can support normal getty configs in /etc/inttab... - Now implements RX throttling. When the line discipline says it doesn't want any more data, only packets in flight will be delivered (currently, max 1K/8K at full/high speeds) until it unthrottles the data. - Supports low_latency. This is a good policy for all USB serial adapters, since it eliminates scheduler overhead on RX paths. This also includes much cleanup including better comments, fixing memory leaks and other bugs (including some locking fixes), messaging cleanup, and an interface audit and tightening. This added up to a significant object code shrinkage, on the order of 20% (!) depending on CPU and compiler. A separate patch actually kicks in this new code, using the functions declared in this new header, and removes the previous glue.

2008-06-15[ARM] 5080/1: touch PSSR_OTGPH only on pxa27x in ohci-pxa27x and pxa27x_udcPhilipp Zabel
and include pxa2xx-regs.h as build fix since PSSR definitions moved from pxa-regs.h into pxa2xx-regs.h. Note: This change is temporary as pxa27x processor specific code will be finally moved elsewhere (both drivers should support pxa3xx, too).

2008-05-19[ARM] pxa: separate PXA25x and PXA27x UDC register definitionsRussell King
The PXA25x and PXA27x USB device controller register definitions are different. Currently, they live side by side in pxa-regs.h, but only one set is available depending on the setting of PXA25x or PXA27x. This means that if we build to support both PXA25x and PXA27x, the PXA27x definitions are unavailable, even to PXA27x specific code. Remove these definitions from pxa-regs.h, and place them in separate files. Include these files where appropriate. Note: according to the dependencies in drivers/usb/gadget/Kconfig, we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the platform devices from pxa27x.c and pxa3xx.c.

2008-05-14USB: atmel_usba_udc fixes, mostly disconnect()David Brownell
Various fixes to Atmel's high speed UDC driver. * Issue some missing disconnect() calls. Currently they are only made when VBUS power goes away (on boards where the driver can sense such changes), but that's not enough for gadget drivers to clean out all the state that's needed. Missing calls were: - After USB reset, before starting enumeration. - When unregistering a gadget driver, before unbind(). * Don't assume gadget drivers provide disconnect callbacks; make sure to not call through a null pointer! * When the driver doesn't provide an unbind() callback, refuse to unregister it. Also remove two bogus "error" messages: * Related to mis-handling of disconnect() ... don't emit error messages for disconnect() handlers that disable endpoints. All of them should be doing that; the problem is (unfixed) oddness in atmel_usba_udc. * Don't emit a diagnostic for a curious and transient nonfatal error that shows up sometimes with EP0. Those messages spammed syslog, for no good reason.
