The original SIO devices require a control byte for every packet written. Clean up the unnecessarily messy implementation of this. Signed-off-by:

Switch to the generic, multi-urb, write implementation. Note that this will also make it fairly easy to use the generic fifo-based write implementation: simply unset the multi_urb_write flag and modify prepare_write_buffer (or unset if not using a legacy SIO device). This may be desirable for instance on an embedded system where optimal throughput at high baudrates may not be as important as other factors (e.g. no allocations during runtime and less pressure on host stack).

Use the resource_size function instead of manually calculating the resource size. This reduces the chance of introducing off-by-one errors. Signed-off-by:

This patch (as1377) simplifies the code in usb_sg_init(), without changing its functionality. It also removes a couple of unused fields from the usb_sg_request structure. Signed-off-by:

This USB video class function driver implements a video capture device from the host's point of view. It creates a V4L2 output device on the gadget's side to transfer data from a userspace application over USB. The UVC-specific descriptors are passed by the gadget driver to the UVC function driver, making them completely configurable without any modification to the function's driver code. Signed-off-by:

Change the type of the URB's 'sg' pointer from a usb_sg_request to a scatterlist. This allows drivers to submit scatter-gather lists without using the usb_sg_wait() interface. It has the added benefit of removing the typecasts that were added as part of patch as1368 (and slightly decreasing the number of pointer dereferences). Signed-off-by:

The max packet length bit mask used for isochronous endpoints should be 0x7FF instead of 0x8FF. 0x8FF will actually clear higher-order bits in the max packet length field. This patch applies to 2.6.34-rc6. Signed-off-by:

When a device is disconnected, xhci_free_virt_device() is called. Ramya found that if the device had streams enabled, and then the driver freed the streams with a call to usb_free_streams(), then about a minute after he had called this, his machine crashed with a Bad DMA error. It turns out that xhci_free_virt_device() would attempt to free the endpoint's stream_info data structure if it wasn't NULL, and the free streams function was not setting it to NULL after freeing it.

Fix mos7720 Kconfig dependencies. When an enabled bool selects a tristate, the tristate becomes =y, even if it should be limited to modular, so limit the bool kconfig option to configs that will build cleanly.

No functionality added or bugs fixed, just improved code consistency and (hopefully) readability by replacing send_mos_cmd with the register read & write functions that were used for parallel port registers. Also shortens overall file length. Thoroughly tested, with emphasis on regression testing the serial port. Signed-off-by:

Add support for the parallel port on the moschip MCS7715 device. The port registers itself with the parport subsystem as a low-level driver. A separate entry to the kernel configuration is added beneath that for the mos7720, to avoid the need to link with the parport subsystem code for users who don't have or don't want the parallel port. Only compatibility mode is currently supported (no ECP/EPP). Tested with both moschip devices (7720 and 7715) on UP and SMP hosts, including regression testing of serial port, concurrent operation of serial and parallel ports, and various connect / disconnect scenarios.

Daniel Mack authored
For more clearance what the functions actually do, usb_buffer_alloc() is renamed to usb_alloc_coherent() usb_buffer_free() is renamed to usb_free_coherent() They should only be used in code which really needs DMA coherency. All call sites have been changed accordingly, except for staging drivers. Signed-off-by:
