git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: changes for v3.18 merge window Quite big pull request this time. Audio and UVC gadgets can now be used with our configfs-based binding. We have three PHY drivers being removed because a new one has been added using new PHY framework. Gadget framework got a new ->reset callback preparing for some other changes to come on next merge window. A few new drivers came in as well; among those we have a new UDC driver from Xilinx and two new glue layers for DWC3 (ST and Qualcomm). DWC3 also learned about tracepoints which will help debugging quite a bit. Other than that, a big series of non-critical fixes and cleanups. All patches have been on linux-next for quite a bit of time and I boot tested these changes on platforms I have access to and work with mainline. Signed-of-by: Felipe Balbi <balbi@ti.com>

2014-09-16usb: gadget: f_fs: virtual endpoint address mappingRobert Baldyga2-2/+23
This patch introduces virtual endpoint address mapping. It separates function logic form physical endpoint addresses making it more hardware independent. Following modifications changes user space API, so to enable them user have to switch on the FUNCTIONFS_VIRTUAL_ADDR flag in descriptors. Endpoints are now refered using virtual endpoint addresses chosen by user in endpoint descpriptors. This applies to each context when endpoint address can be used: - when accessing endpoint files in FunctionFS filesystemi (in file name), - in setup requests directed to specific endpoint (in wIndex field), - in descriptors returned by FUNCTIONFS_ENDPOINT_DESC ioctl. In endpoint file names the endpoint address number is formatted as double-digit hexadecimal value ("ep%02x") which has few advantages - it is easy to parse, allows to easly recognize endpoint direction basing on its name (IN endpoint number starts with digit 8, and OUT with 0) which can be useful for debugging purpose, and it makes easier to introduce further features allowing to use each endpoint number in both directions to have more endpoints available for function if hardware supports this (for example we could have ep01 which is endpoint 1 with OUT direction, and ep81 which is endpoint 1 with IN direction). Physical endpoint address can be still obtained using ioctl named FUNCTIONFS_ENDPOINT_REVMAP, but now it's not neccesary to handle USB transactions properly.

I'm seeing problems with a d-link dwcl-g122 wifi dongle that someone sent me. There are reports of other wifi dongles with the same/similar problem. The devices appear to be NAKing to the point of confusing the dwc2 driver completely. The attached patch helps with my d-link dwl-g122 - it's adapted from the Raspberry Pi dwc_otg driver, which is a modified version of the Synopsys vendor driver.

2014-09-12xhci: fix oops when xhci resumes from hibernate with hw lpm capable devicesMathias Nyman1-2/+10
Resuming from hibernate (S4) will restart and re-initialize xHC. The device contexts are freed and will be re-allocated later during device reset. Usb core will disable link pm in device resume before device reset, which will try to change the max exit latency, accessing the device contexts before they are re-allocated. There is no need to zero (disable) the max exit latency when disabling hw lpm for a freshly re-initialized xHC. So check that device context exists before doing anything. The max exit latency will be set again after device reset when usb core enables the link pm.

The xhci driver will OOPS on resume from S2/S3 if dma_alloc_coherent() is out of memory. This is a result of two things: 1. xhci_mem_cleanup() in xhci-mem.c free's xhci->lpm_command if it's not NULL, but doesn't set it to NULL after the free. 2. xhci_mem_cleanup() is called twice on resume, once for normal restart and once from xhci_mem_init() if dma_alloc_coherent() fails, resulting in a free of xhci->lpm_command that has already been freed. The fix is to set xhci->lpm_command to NULL after freeing it.

2014-09-12xhci: Fix null pointer dereference if xhci initialization failsMathias Nyman1-1/+1
If xhci initialization fails before the roothub bandwidth domains (xhci->rh_bw[i]) are allocated it will oops when trying to access rh_bw members in xhci_mem_cleanup().

2014-09-12storage: Add single-LUN quirk for Jaz USB AdapterMark1-0/+6
The Iomega Jaz USB Adapter is a SCSI-USB converter cable. The hardware seems to be identical to e.g. the Microtech XpressSCSI, using a Shuttle/ SCM chip set. However its firmware restricts it to only work with Jaz drives. On connecting the cable a message like this appears four times in the log: reset full speed USB device number 4 using uhci_hcd That's non-fatal but the US_FL_SINGLE_LUN quirk fixes it.

git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm Pull ACPI and power management fixes from Rafael Wysocki: "These are regression fixes (cpufreq, ACPI battery) and fixes for stuff that never worked correctly (ACPI RTC operation region handler and PM domain implementation in the ACPI LPSS driver). Specifics: - Fix for the cpufreq Operation Performance Points (OPP) code where a recent commit added a kcalloc() call with an incorrect ordering of arguments. From Anand Moon. - Reverts of two ACPI battery commits that caused incorrect diagnostic information to be printed to dmesg in some cases from Bjørn Mork. - Fix for the ACPI RTC operation region handler that applied the & operator to an argument already representing an address and that caused it to overwrite its own argument instead of writing to the address contained in it as expected. From Chun-Yi Lee. - Fix for the PM domain implementation in the ACPI LPSS (Low-Power Subsystem) driver where one callback pointer pointed to a wrong routine and one was NULL, but it shouldn't.
