It is enough to protect accesses to reject field of urb by marking it as atomic_t,also it is the only reason of existence of usb_reject_lock,so remove the lock to make code more clean. Signed-off-by:

This patch (as1185) makes usbcore take advantage of the bus notifications sent out by the driver core. Now we can create all our device and interface attribute files before the device or interface uevent is broadcast. A side effect is that we no longer create the endpoint "pseudo" devices at the same time as a device or interface is registered -- it seems like a bad idea to try registering an endpoint before the registration of its parent is complete. So the routines for creating and removing endpoint devices have been split out and renamed, and they are called explicitly when needed. A new bitflag is used for keeping track of whether or not the interface's endpoint devices have been created, since (just as with the interface attributes) they vary with the altsetting and hence can be changed at random times.

The DPCM subdriver is a little peculiar, in that it's meant to support devices where LUN 0 is Compact Flash and uses the CB transport whereas LUN 1 is SmartMedia and uses the SDDR09 transport. Thus DPCM isn't really a transport in itself; it's more like a demultiplexer. Much of the DPCM code is part of the SDDR09 subdriver already, and the remaining part is fairly small. This patch (as1182) moves that extra piece into sddr09.c, thereby eliminating dpcm.c. Also eliminated is the Kconfig entry for DPCM support; it is now listed as part of the SDDR09 entry. In order to make sure that the semantics are the same as before, each unusual_devs entry for DPCM is now present twice: once with DPCM support if SDDR09 is configured (as before), and once with the SINGLE_LUN flag and CB support otherwise.

Contains fixes so probe on x86 PCI runs, apparently I'm first to try this. Several fixes to memory access to probe host scratch register. Previously would bug check on chip_addr var used uninitialized. Scratch reg write failed in one instance due to 16-bit initial access mode, so added "& 0x0000ffff" to the readl as fix. Includes some general cleanup - remove global vars, organize memory map resource use. Signed-off-by:

This patch (as1177) modifies the USB core suspend and resume routines. The resume functions now will take a pm_message_t argument, so they will know what sort of resume is occurring. The new argument is also passed to the port suspend/resume and bus suspend/resume routines (although they don't use it for anything but debugging). In addition, special pm_message_t values are used for user-initiated, device-initiated (i.e., remote wakeup), and automatic suspend/resume. By testing these values, drivers can tell whether or not a particular suspend was an autosuspend. Unfortunately, they can't do the same for resumes -- not until the pm_message_t argument is also passed to the drivers' resume methods. That will require a bigger change. IMO, the whole Power Management framework should have been set up this way in the first place. Signed-off-by:

This patch (as1178) uses the new round_jiffies_up_relative() routine for setting the autosuspend delayed_work timer. It's appropriate since we don't care too much about the exact length of the delay, but we don't want it to be too short (rounded down). Signed-off-by:

gpio_vbus provides simple GPIO VBUS sensing for peripheral controllers with an internal transceiver. Optionally, a second GPIO can be used to control D+ pullup. It also interfaces with the regulator framework to limit charging currents when powered via USB. gpio_vbus requests the regulator supplying "vbus_draw" and can enable/disable it or limit its current depending on USB state.

This moves the isp1301-omap driver from the drivers/i2c/chips directory (which will be shrinking) into a new drivers/usb/otg directory (which will grow, with more drivers and utilities). Note that OTG infrastructure needs to be initialized before either host or peripheral side USB support, and may be needed before for pure host or pure peripheral configurations. Signed-off-by:

Random host-side MUSB updates, mostly relating to better diagnostics: + Improve diagnostics on host side: - tx flush fifo: * Avoid hundreds of duplicate TX FIFONOTEMPTY messages * make "Can't flush TX fifo" a warning, and say which endpoint - giveback: * use correct status code * show completion function name not just URB pointer - Fix annoying "1 bytes" (should be "1 byte") + Be more consistent about failing init of unusable fifo_mode It's not clear why that "can't flush TX fifo" message appears, though it might relate to disconnection; I see it not infrequently Signed-off-by: -

Since num is unsigned, it would seem better to use simple_strtoul that simple_strtol.

This patch (as1175) makes usb-storage set a SCSI device's request-queue bounce limit such that all buffers will be located in addressable memory (i.e., not in high memory) if the host controller's dma_mask is NULL. This is necessary when the host controller doesn't support DMA: If a buffer is in high memory then the both the virtual and DMA addresses produced by the scatter-gather library will be NULL, preventing the HCD from accessing the buffer's data. In particular, the isp1760 driver needs this when used on a system with more than 1 GB of memory. Signed-off-by:
