| | | | | | | | | | | | When applying commit 7d26b58 (fix failure path in dwc3_pci_probe()), I mistakenly left out one of the possible failures where we would return success even on the error case.

| | | | | | | | | | When a urb is submitted to xHCI driver, check if queueing the urb will make the enqueue pointer advance into dequeue seg and expand the ring if it occurs.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver can be used as a subdriver of another USB driver, allowing it to export a Device Managment interface consisting of a single interrupt endpoint with no dedicated USB interface. Some devices provide a Device Management function combined with a wwan function in a single USB interface having three endpoints (bulk in/out + interrupt). If the interrupt endpoint is used exclusively for DM notifications, then this driver can support that as a subdriver provided that the wwan driver calls the appropriate entry points on probe, suspend, resume, pre_reset, post_reset and disconnect. The main driver must have full control over all interface related settings, including the needs_remote_wakeup flag. A manage_power function must be provided by the main driver. A manage_power stub doing direct flag manipulation is used in normal driver mode.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The kernel doc entry for usb_unlink_urb() contains the phrase "This request is always asynchronous.". The "always" leads to the assumption that the ->complete() callback is not called from within usb_unlink_urb(). This is not true. The HCD is allowed to call the ->complete() from within ->urb_dequeue() if it is appropriate for the hardware. This patch updates the kernel doc so usb-device driver authors make sure to drop all locks (and make sure it is okay to drop them) which are acquired by the complete callback before calling usb_unlink_urb().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch updates the cp210x driver to support CP210x multiple interface devices devices from Silicon Labs. The existing driver always sends control requests to interface 0, which is hardcoded in the usb_control_msg function calls. This only allows for single interface devices to be used, and causes a bug when using ports on an interface other than 0 in the multiple interface devices. Here are the changes included in this patch: - Updated the device list to contain the Silicon Labs factory default VID/PID for multiple interface CP210x devices - Created a cp210x_port_private struct created for each port on startup, this struct holds the interface number - Added a cp210x_release function to clean up the cp210x_port_private memory created on startup - Modified usb_get_config and usb_set_config to get a pointer to the cp210x_port_private struct, and use the interface number there in the usb_control_message wIndex param Signed-off-by: Preston Fick <preston.fick@silabs.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

It includes a new glue layer for Samsung's Exynos platform, a simplification of memory management on DWC3 driver by using dev_xxx functions, a few optimizations to IRQ handling by dropping memcpy() and using bitshifts, a fix for TI's OMAP5430 TX Fifo Allocation, two fixes on USB2 test mode implementation (one on debugfs and one on ep0), and several minor changes such as whitespace cleanups, simplification of a few parts of the code, decreasing a long delay to something a bit saner, dropping a header which was included twice and so on. The highlight on this merge is the support for Samsung's Exynos platform, increasing the number of different users for this driver to three. Note that Samsung Exynos glue layer will only compile on platforms which provide implementation for the clk API for now. Once Samsung supports pm_runtime, that limitation can be dropped from the Makefile. Conflicts: drivers/usb/dwc3/gadget.c

| | | | | | | | | | | | | | | | | | | | | | | | | | | The loop in dwc3_gadget_set_link_state() was using a udelay(500), which is a long time to delay in interrupt context. Change it to udelay(5) and increase the loop count to match. Signed-off-by: Paul Zimmerman <paulz@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
