NOP transceiver is used by all the usb transceiver which are mostly autonomous and doesn't require any programming or which are built into the usb ip itself.NOP transceiver only allocates the memory for struct xceiv and calls otg_set_transceiver() so function call to otg_get_transceiver() will return a valid transceiver. NOP transceiver device should be registered by calling usb_nop_xceiv_register() from platform files. Signed-off-by:

Remove some pointless messages from the FTDI serial driver; I found these filling up syslog on one system. Also remove a pointless "break" after a "return" in the same area. Signed-off-by:

Oliver Neukum authored
This removes an unnecessary check for autoresume from the generic resume method. The check has been obsoleted by the now delayed increase of the usage counter which makes the error this check prevented impossible. This change allows drivers which only use the bulk read URB the use of the generic method even if they support autosuspend. Signed-off-by:

USB: serial: introduce a flag into the usb serial layer to tell drivers that their URBs are killed due to suspension This patch introduces a flag into the usb serial layer to tell drivers that their URBs are killed due to suspension.

Add the vbus_draw() callback to inform the transceiver, if it exists, how much current may be drawn. The decision is taken on gadget driver side using the configuration chosen by the host and its bMaxPower field. Some systems can use the host's VBUS supply to augment or recharge a battery. (There's also a default of 100 mA for unconfigured devices, or 8 mA if they're OTG devices.) Signed-off-by:

When a transceiver driver is used, no automatic udc enable is done. The transceiver (OTG or not) should : - take care of VBus sensing - call usb_gadget_vbus_connect() - call usb_gadget_vbus_disconnect() The pullup should remain within this driver's management, either by gpio_pullup of udc_command() fields.

On vbus_session() call, optionally activate D+ pullup resistor and enable the udc, or deactivate D+ pullup resistor and disable the udc. It is intentional to not handle any VBus sense related irq. An external transceiver driver (like gpio_vbus) should catch VBus sense signal, and call usb_gadget_vbus_connect() or usb_gadget_vbus_disconnect(). Signed-off-by:

The usblp in 2.6.18 polled for status regardless if we actually needed it. At some point I dropped it, to save the batteries if nothing else. As it turned out, printers exist (e.g. Canon BJC-3000) that need prodding this way or else they stop. This patch restores the old behaviour. If you want to save battery, don't leave jobs in the print queue. I tested this on my printers by printing and examining usbmon traces to make sure status is being requested and printers continue to print. Tuomas Jäntti verified the fix on BJC-3000. Signed-off-by:

This patch (as1203) increases the max_sector limit for USB tape drives. By default usb-storage sets max_sectors to 240 (i.e., 120 KB) for all devices. But tape drives need a higher limit, since tapes can and do have very large block sizes. Without the ability to transfer an entire large block in a single command, such tapes can't be used. This fixes Bugzilla #12207. Signed-off-by:

Restore some code that was wrongly dropped from the RNDIS driver, and caused interop problems observed with OpenMoko. The issue is with hardware which needs help conforming to part of the USB 2.0 spec (section 8.5.3.2); some can automagically send a ZLP in response to an unexpected IN, but not all chips will do that. We don't need to check the packet length ourselves the way earlier code did, since the UDC must already check it. But we do need to tell the UDC when it must force a short packet termination of the data stage. (Based on a patch from Aric D. Blumer <aric at sdgsystems.com>) Signed-off-by:

Apparently the Configuration and Interface strings aren't used as often as the Vendor, Product, and Serial strings. In at least one device (a Saitek Cyborg Gold 3D joystick), attempts to read the Configuration string cause the device to stop responding to Control requests. This patch (as1226) adds a quirks flag, telling the kernel not to read a device's Configuration or Interface strings, together with a new quirk for the offending joystick. Reported-by:

With a sufficiently new compiler and binutils, code which wasn't previously generating .eh_frame sections has begun to. Certain architectures (powerpc, in this case) may generate unexpected relocation formats in response to this, preventing modules from loading. While the new relocation types should probably be handled, revert to the previous behaviour with regards to generation of .eh_frame sections. (This was reported against Fedora, which appears to be the only distro doing any building against gcc-4.4 at present: RH bz#486545.) Signed-off-by:

This patch fixes bug #12208: Bug-Entry : http://bugzilla.kernel.org/show_bug.cgi?id=12208 Subject : uml is very slow on 2.6.28 host This turned out to be not a scheduler regression, but an already existing problem in ptrace being triggered by subtle scheduler changes. The problem is this: - task A is ptracing task B - task B stops on a trace event - task A is woken up and preempts task B - task A calls ptrace on task B, which does ptrace_check_attach() - this calls wait_task_inactive(), which sees that task B is still on the runq - task A goes to sleep for a jiffy - ... Since UML does lots of the above sequences, those jiffies quickly add up to make it slow as hell. This patch solves this by not rescheduling in read_unlock() after ptrace_stop() has woken up the tracer. Thanks to Oleg Nesterov and Ingo Molnar for the feedback. Signed-off-by:

Also, since we fully construct phy_bus_id in the _probe() routine, we no longer need ->phy_address and ->mdio_bus fields in ucc_geth_info structure. I wish the patch would be a bit shorter, but it seems like the only way to fix the issue in a sane way. Luckily, the patch has been tested with real PHYs and fixed-link, so no further regressions expected. Reported-by:

This fixes a locking bug in the dm9000 driver. It calls request_irq() without setting IRQF_DISABLED ... which is correct for handlers that support IRQ sharing, since that behavior is not guaranteed for shared IRQs. However, its IRQ handler then wrongly assumes that IRQs are blocked. So the fix just uses the right spinlock primitives in the IRQ handler. NOTE: this is a classic example of the type of bug which lockdep currently masks by forcibly setting IRQF_DISABLED on IRQ handlers that did not request that flag. Signed-off-by:
