This patch (as1656) adds a module parameter to the net2280 UDC driver to force full-speed operation. It is intended for testing purposes, where one wants to check how well a full-speed device performs when attached to a high-speed bus. Without this parameter it would be necessary to interpose a full-speed hub; otherwise the net2280 would connect at high speed.

The usbtest driver includes some rather simple-minded logic for selecting an altsetting to test. It doesn't work well for the g_zero gadget, because it selects altsetting 0 (which doesn't have isochronous endpoints) rather than altsetting 1 (which does have them, if the gadget's hardware supports them). This prevents usbtest's isochronous tests (15, 16, 22, and 23) from working with g_zero. Since g_zero is one of the most common gadget drivers used for USB testing, usbtest should do a better job of supporting it. But since some programs may rely on the current scheme for selecting altsettings, I didn't want to change it. Instead, this patch (as1655) adds a module parameter to usbtest, which can be used to override the default altsetting. Since usbtest is never used by normal users (most distributions probably don't even build it), the new module parameter won't inconvenience anybody. In any case, it is entirely optional -- leaving it unset preserves the existing behavior. The patch also fixes a related bug in usbtest: After selecting an altsetting, the driver neglects to store its selection.

This reverts commit 88bb965e. The linux-next branch of linux-pm tree has replaced acpi_power_resource_(un)register_device() with new routines. Commit 88bb965e will cause conflict in the linux-next tree. So revert it and this will not affect other functions. Will send a new patch with new routines after 3.9 merge window.

Pull btrfs fixes from Chris Mason: "It turns out that we had two crc bugs when running fsx-linux in a loop. Many thanks to Josef, Miao Xie, and Dave Sterba for nailing it all down. Miao also has a new OOM fix in this v2 pull as well. Ilya fixed a regression Liu Bo found in the balance ioctls for pausing and resuming a running balance across drives. Josef's orphan truncate patch fixes an obscure corruption we'd see during xfstests. Arne's patches address problems with subvolume quotas. If the user destroys quota groups incorrectly the FS will refuse to mount.

This patch is to set power.async_suspend for usb port in order to allow it to be suspended and resumed asynchronously during system sleep transitions. The power.async_suspend flag is also set for devices that don't have suspend or resume callbacks, because otherwise they would make the main suspend/resume thread wait for their "asynchronous" children (during suspend) or parents (during resume), effectively negating the possible gains from executing these devices' suspend and resume callbacks asynchronously.

This patch is to add usb port auto power off mechanism. When usb device is suspending, usb core will suspend usb port and usb port runtime pm callback will clear PORT_POWER feature to power off port if all conditions were met. These conditions are remote wakeup disable, pm qos NO_POWER_OFF flag clear and persist enable. When it resumes, power on port again. Add did_runtime_put in the struct usb_port to ensure pm_runtime_get/put(portdev) to be called pairedly. Set did_runtime_put to true when call pm_runtime_put(portdev) during suspending. The pm_runtime_get(portdev) only will be called when did_runtime_put is set to true during resuming. Set did_runtime_put to false after calling pm_runtime_get(portdev). Make clear_port_feature() and hdev_to_hub() as global symbol. Rename clear_port_feature() to usb_clear_port_feature() and hdev_to_hub() to usb_hub_to_struct_hub(). Extend hub_port_debounce() with the fuction of debouncing to be connected. Add two wraps: hub_port_debounce_be_connected() and hub_port_debouce_be_stable(). Increase HUB_DEBOUNCE_TIMEOUT to 2000 because some usb ssds needs around 1.5 or more to make the hub port status to be connected steadily after being powered off and powered on.

Felipe writes: usb: xceiv: patches for v3.9 merge window Two new PHY drivers coming here: one for Samsung, one for OMAP. Both architectures are adding USB3 support to mainline kernel. The PHY layer now allows us to have mulitple PHYs of the same type, which is necessary for platforms which provide more than one USB peripheral port. There's also a few cleanups here: removal of __dev* annotations, conversion of a cast to to_delayed_work(), and mxs-phy learns about ->set_suspend.

Merge tag 'gadget-for-v3.9' of git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: gadget: patches for v3.9 merge window finally getting rid of the old ->start()/->stop() methods in favor of the better and improved ->udc_start()/->udc_stop(). There were surprisingly quite a few users left, but all of them have been converted. f_mass_storage removed some dead code, which is always great ;-) There's also a big cleanup to the gadget framework from Sebastian which gets us a lot closer to having only function drivers in kernel and move over to configfs-based binding. Other than these, there's the usual set of cleanups: s3c UDCs are moving over to devm_regulator_bulk_get() API, at91_udc removed an unnecessary check for work_pending() before scheduling and there's the removal of an unused variable from uac2_pcm_trigger().

Felipe writes: usb: dwc3: patches for v3.9 merge window We're saving some extra memory now by being a lot more conservative when allocating our event buffers. Our default HIRD threshold value was mistakenly set as one of the unsupported which would cause undefined behavior. Turns out that it broke OMAP5 ES2.0, so we're fixing it now by setting the maximum allowed HIRD threshold (12). Quite a few fixes to Isochronous transfers and scatter/gather support from Pratyush. We're also starting to support devicetree-based probe with the latest changes from Kishon. The usual set of cleanups also available: converting debugfs regdump utility to regsets, better "compatible" strings for Exynos platforms and the removal of the dependency for Host and Gadget; now dwc3 can be compiled host-only, device-only, and/or Dual-Role.

Felipe writes: usb: musb: patches for v3.9 merge window Mostly fixes all over which weren't urgent enough for the late -rc cycle. There is a Double Buffering fix for Host Mode TX, a dependency fix for the transceiver driver, some fixes to the error path and a fix for the use of omap_musb_maibox. Other than these fixes, there a removal duplicate headers from the dsps glue layer and removal of redundant assignments in omap2430_probe().

In order to add support for multipe PHY's of the same type, new API's for adding PHY and getting PHY has been added. Now the binding information for the PHY and controller should be done in platform file using usb_bind_phy API. And for getting a PHY, the device pointer of the USB controller and an index should be passed. Based on the binding information that is added in the platform file, usb_get_phy_dev will return the appropriate PHY. Already existing API's to add and get phy by type is not removed. These API's are deprecated and will be removed once all the platforms start to use the new API. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
