usb: xhci: add missing dma-mapping.h includes

2013-07-31T18:27:18+00:00

A randconfig build hit the following build errors because xhci.c and
xhci-mem.c use dma mapping functions but don't include
. Add the missing includes to fix the build errors.

drivers/usb/host/xhci.c In function 'xhci_gen_setup':
drivers/usb/host/xhci.c +4872 : error: implicit declaration of function 'dma_set_mask'
drivers/usb/host/xhci.c +4872 : error: implicit declaration of function 'DMA_BIT_MASK'

usb: core: don't try to reset_device() a port that got just disconnected

2013-07-31T16:51:45+00:00

The USB hub driver's event handler contains a check to catch SuperSpeed
devices that transitioned into the SS.Inactive state and tries to fix
them with a reset. It decides whether to do a plain hub port reset or
call the usb_reset_device() function based on whether there was a device
attached to the port.

However, there are device/hub combinations (found with a JetFlash
Transcend mass storage stick (8564:1000) on the root hub of an Intel
LynxPoint PCH) which can transition to the SS.Inactive state on
disconnect (and stay there long enough for the host to notice). In this
case, above-mentioned reset check will call usb_reset_device() on the
stale device data structure. The kernel will send pointless LPM control
messages to the no longer connected device address and can even cause
several 5 second khubd stalls on some (buggy?) host controllers, before
finally accepting the device's fate amongst a flurry of error messages.

This patch makes the choice of reset dependent on the port status that
has just been read from the hub in addition to the existence of an
in-kernel data structure for the device, and only proceeds with the more
extensive reset if both are valid.

USB: serial: ftdi_sio: add more RT Systems ftdi devices

2013-07-29T20:38:38+00:00

RT Systems makes many usb serial cables based on the ftdi_sio driver for
programming various amateur radios.  This patch is a full listing of
their current product offerings and should allow these cables to all
be recognized.

usb: chipidea: fix the build error with randconfig

2013-07-29T17:54:31+00:00

Using below  configs, the compile will have error:
ERROR: "ehci_init_driver" undefined!

.config:
CONFIG_USB_CHIPIDEA=m
CONFIG_USB_CHIPIDEA_HOST=y
CONFIG_USB_CHIPIDEA_DEBUG=y

The reason is chipidea host uses symbol from ehci, but ehci
is not compiled. Let the chipidea host depend on
ehci even it is built as module.

usb: fixes for v3.11-rc3

Here are some fixes for v3.11-rc3. Mostly related to
the recent conversion to configfs done on the gadget
drivers, but we also have a fix for MUSB resources
on platforms which need 3 resources instead of 2, and
a fix for the sysfs_notify() call on udc-core.c which
was notifying an unexistent file.

usb: gadget: udc-core: fix the typo of udc state attribute

2013-07-29T11:15:38+00:00

The name of udc state attribute file under sysfs is registered as
"state", while usb_gadget_set_state take it as "status" when it's
going to update. This patch fixes the typo.

2013-07-29T11:15:23+00:00

The compatibility layer which the USBF_PHONET_INCLUDED was a part of
is no longer present - the USBF_PHONET_INCLUDED is not #defined by anyone
anymore, so the ifndef is always true. Removing it.

usb: gadget: multi: fix error return code in cdc_do_config()

2013-07-29T11:15:18+00:00

Fix to return a negative error code from the error handling
case instead of 0, as returned elsewhere in this function.

Introduced by commit 59835a (usb: gadget: multi: use
function framework for ACM.)

Make rndis_do_config() consistent with cdc_do_config() in the way it
handles returning the PTR_ERR(f_acm_*).

USB: mos7840: fix pointer casts

Silence compiler warnings on 64-bit systems introduced by commit
05cf0dec ("USB: mos7840: fix race in led handling") which uses the
usb-serial data pointer to temporarily store the device type during
probe but failed to add the required casts.
