git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.10 merge window Here is the big Gadget & PHY pull request. Many of us have been really busy lately getting multiple drivers to a better position. Since this pull request is so large, I will divide it in sections so it's easier to grasp what's included. - cleanups: . UDC drivers no longer touch gadget->dev, that's now udc-core responsibility . Many more UDC drivers converted to usb_gadget_map/unmap_request() . UDC drivers no longer initialize DMA-related fields from gadget's device structure . UDC drivers don't touch gadget.dev.driver directly . UDC drivers don't assign gadget.dev.release directly . Removal of some unused DMA_ADDR_INVALID . Introduction of CONFIG_USB_PHY . All phy drivers have been moved to drivers/usb/phy and renamed to a common naming scheme . Fix PHY layer so it never returns a NULL pointer, also fix all callers to avoid using IS_ERR_OR_NULL() . Sparse fixes all over the place . drivers/usb/otg/ has been deleted . Marvel drivers (mv_udc, ehci-mv, mv_otg and mv_u3d) improved clock usage - new features: . UDC core now provides a generic way for tracking and reporting UDC's state (not attached, resuming, suspended, addressed, default, etc) . twl4030-usb learned that it shouldn't be enabled during init . Full DT support for DWC3 has been implemented . ab8500-usb learned about pinctrl framework . nop PHY learned about DeviceTree and regulators . DWC3 learned about suspend/resume . DWC3 can now be compiled in host-only and gadget-only (as well as DRD) configurations . UVC now enables streaming endpoint based on negotiated speed . isp1301 now implements the PHY API properly . configfs-based interface for gadget drivers which will lead to the removal of all code which just combines functions together to build functional gadget drivers. . f_serial and f_obex were converted to new configfs interface while maintaining old interface around. - non-critical fixes: . UVC gadget driver got fixes for Endpoint usage and stream calculation . ab8500-usb fixed unbalanced clock and regulator API usage . twl4030-usb got a fix for when OMAP3 is booted with cable connected . fusb300_udc got a fix for DMA usage . UVC got fixes for two assertions of the USB Video Class Compliance specification revision 1.1 . build warning issues caused by recent addition of __must_check to regulator API These are all changes which deserve a mention, all other changes are related to these one or minor spelling fixes and other similar tasks.

2013-04-02usb: ehci: mv_ehci: remove unused clockChao Xie
The origianl understanding of clock is wrong. The EHCI controller only have one clock input. Passing clock name by pdata is wrong. The clock is defined by device iteself.

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().

the clock common driver changes, and arch-mmp will make use of the common clock driver instead of its own.

2012-08-10drivers/usb/host/ehci-mv.c: use devm_ functionsJulia Lawall
The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function. A new label name is created in one case to better reflect the contents of the error-handling code.

2012-07-09EHCI: centralize controller initializationAlan Stern
This patch (as1564c) converts the EHCI platform drivers to use the central ehci_setup() routine for generic controller initialization rather than each having its own idiosyncratic approach. The major point of difficulty lies in ehci-pci's many vendor- and device-specific workarounds. Some of them have to be applied before calling ehci_setup() and some after, which necessitates a fair amount of code motion. The other platform drivers require much smaller changes. One point not addressed by the patch is whether ports should be powered on or off following initialization. The different drivers appear to handle this pretty much at random. In fact it shouldn't matter, because the hub driver turns on power to all ports when it binds to the root hub. Straightening that out will be left for another day.

2012-07-02usb: phy: fix return value check of usb_get_phyKishon Vijay Abraham I
usb_get_phy will return -ENODEV if it's not able to find the phy.

2012-06-25usb: otg: support for multiple transceivers by a single controllerKishon Vijay Abraham I
Add a linked list for keeping multiple PHY instances with different types so that we can have separate USB2 and USB3 PHYs on one single board. _get_phy_ has been changed so that the controller gets the transceiver by type. _remove_phy_ has been added to let the phy be removed from the phy list.
