This patch zeroes some variables when usb_gadget_register_driver() fails. gadgetfs does a dummy registration to get the name of the USB driver and then waits for user-land driver. If someone plugs the cable in the meantime, bad things happen, because at91_udc has been left in inconsistent state. Signed-off-by:

This patch allows gadget drivers that support high speed (e.g. gadgetfs) to work properly with at91_udc. Fix suggested by Milan Svoboda in http://marc.theaimsgroup.com/?l=linux-usb-devel&m=115822184711817Signed-off-by:

ELAN's U132 is a USB to CardBus OHCI controller adapter, designed specifically for CardBus 3G data cards to function in machines without a CardBus slot. The "ftdi-elan" module is a USB client driver, that detects a supported CardBus OHCI controller plugged into the U132 adapter and thereafter provides the conduit for for access by the "u132-hcd" module. The "u132-hcd" module is a (cut-down OHCI) host controller that supports a single OHCI function of the CardBus card inserted into the U132 adapter. The problem with the initial implementation is that when the CardBus card inserted into the U132 adapter has multiple functions (and a CardBus card can support up to 4 functions), it was the first function that was arbitrarily choosen. The first batch of 3G cards tested, like the Merlin Qualcomm V620, have two functions each supporting a seperate USB OHCI host controller, of which it was that first function that is wired up to the 3G modem. Then along comes the Vodafone Mobile Connect 3G/GPRS data card, aka "Option GT 3G Quad" as printed on it's rear or "Option N.V. GlobeTrotter Fusion Quad Lite" as read with "lspci -v". And it has the meaningful functionality in the second CardBus function. That presents a problem because it was the "ftdi-elan" module alone that knows how to communicate to the embedded CardBus slot and the "u132-hcd" module alone that knows how to access the pcmcia configuration and CardBus accessible memory space. And of course, the information about attached (internally hardwired) devices is contained within USB configuration embedded somewhere within the CardBus card. If only the "u132-hcd" module probe() interface could return a result code that propagated back to the instigating function platform_device_register() then the "ftdi-elan" module could try an alternative CardBus function. However in spite of the recent changes to the drivers/base/ routines that moved device_attach() from bus_add_device() to bus_attach_device() both of those routines lose the "failed to attach" 0 result code and thus the calling routine, namely device_add() is incapable of propaging the "failed to attach" condition back to platform_device_add() and consequently back to the caller of platform_device_register() Experiments show that patching bus_attach_device() to return ENODEV fails with the kernel locking up very early during boot. But, however, if the patch is restricted to calls from platform_device_add() then it does seem to work. Unfortunately, until the kernel's drivers/base is properly modified to propagate -ENODEV back to the caller of platform_device_register(), it is necessary to "fix" the "ftdi-elan" module by importing knowledge from the "u132-hcd" module. This is the reason for the duplicated functionality introduced in this patch. Signed-off-by:Tony Olech <tony.olech@elandigitalsystems.com> Signed-off-by:

This is an update to the AT91 USB Device (Gadget) driver. Adds support for the Atmel AT91SAM9260 and AT91SAM9261 processors. The only difference is how they handle the pullup pin. [Patch from Patrice Vilchez] Need to clear any pending USB Device interrupts before registering the interrupt handler. The bootloader might have been using the USB Device port. [Patch from Peer Georgi] VBUS detection is handled by a GPIO interrupt which only triggers on a change. Is is therefore necessary to read the current VBUS state explicitly at startup.

This is an update to the AT91 USB Device (Gadget) driver. The base I/O address provided in the platform_device resources is now ioremap()'ed instead of using a statically mapped memory area. This helps portability to the newer AT91sam926x processors. The major change is that we now have to pass a 'struct at91_udc' parameter to at91_udp_read() and at91_udp_write(). Signed-off-by:

I have found a problem where the root_port_reset() goes into an infinite loop and stalls the kernel. This happens when a hardware fault inside the machine occurs during a small timing window. In case of USB device connection, if a USB device responds to hcd_submit_urb(), and later the controller fails before root_port_reset(), root_port_reset() will loop infinitely because ohci_readl() will always return "-1". Such a failure can include ejecting a CardBus OHCI controller. The probability of this problem is low, but it will increase if PnP type usage is frequent. The attached patch can solve this problem and I believe that it is better to fix this problem. Signed-off-by:

Allow gadget drivers to omit the unbind() method. When they're statically linked, that's an appropriate memory saving tweak. Similarly, provide consistent/simpler handling for a should-not-happen error case: removing a peripheral controller driver when a gadget driver is still loaded. Such code dates back to early versions of the first implementation of the gadget API, and has never been triggered. Includes relevant section annotation fixs for gmidi.c, file_storage.c, and serial.c; we don't yet have an "init or exit" annotation. Also some whitespace fixes in gmidi.c (space at EOL, before tabs, etc). Signed-off-by:

Certain boards seem to like to issue false overcurrent notifications, for example on ports that don't have anything connected to them. This looks like a hardware error, at the level of noise to those ports' overcurrent input signals (or non-debounced VBUS comparators). This surfaces to users as truly massive amounts of syslog spam from khubd (which is appropriate for real hardware problems, except for the volume from multiple ports). Using this new "ignore_oc" flag helps such systems work more sanely, by preventing such indications from getting to khubd (and spamming syslog). The downside is of course that true overcurrent errors will be masked; they'll appear as spontaneous disconnects, without the diagnostics that will let users troubleshoot issues like short-circuited cables. In addition, controllers with no devices attached will be forced to poll for new devices rather than relying on interrupts, since each overcurrent event would generate a new interrupt. This patch (as826) is essentially a copy of David Brownell's ignore_oc patch for ehci-hcd, ported to uhci-hcd. Signed-off-by:

When u132-hcd is built, it includes local header ohci.h, which appears to have been intended only for use by ohci-hcd. This throws warnings about functions which are defined and not used. The warnings thrown are because three small functions are implemented in the header, but not declared 'inline', a rather strange affair. Since these functions are small, let's go ahead and define them as 'inline', just like the inline functions surrounding them. This makes things more consistent, and kills the warnings. Signed-off-by:

Added a device specific ioctl function to prevent the disabling of canonical mode. EINVAL is returned for any TCSETSF ioctl that doesn't have ICANON set. This patch is for 2.6.17 or later kernels. When "hwinfo --modem" is executed it opens the funsoft USB serial device and disables canonical mode. The device is kept this way until hwininfo has finished probing any modems on a system. The funsoft device expects to be running in canonical mode. Switching the device to raw mode can cause incomplete data packets and device timeouts. Signed-off-by:
