Eventually this will help us getting rid of in-kernel gadget drivers and only keep function drivers in the kernel. MUSB was taught that it needs to be built for host-only and device-only modes too. We had this support long ago but it involved a ridiculous amount of ifdefs. Now we have a much cleaner approach. Samsung Exynos4 platform now implements HSIC support. We're introducing support for AB8540 and AB9540 PHYs. MUSB module reinsertion now works as expected, before we were getting -EBUSY being returned by the resource checks done on driver core. DWC3 now has minimum support for TI's AM437x series of SoCs. OMAP5 USB3 PHY learned one extra DPLL configuration values because that PHY is reused in TI's DRA7xx devices. We're introducing support for Faraday fotg210 UDCs. Last, but not least, the usual set of non-critical fixes and cleanups ranging from usage of platform_{get,set}_drvdata to lock improvements.

|/ | | | | | | | | | | | | | | | If the glue layer is removed first (core layer later), it deletes the phy device first, then the core device. But at core's removal, it still uses PHY's resources, it may cause kernel's oops. It is much like the problem Paul Zimmerman reported at: http://marc.info/?l=linux-usb&m=136547502011472&w=2. Besides, it is reasonable the PHY is deleted at last as the controller is the PHY's user.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Glue needs to be freed on exiting the function in an error case. Furthermore, pci, which is the first argument to the probe function should not be freed before leaveing the function, as it is reused at the call site. So the free of pci is changed to free glue instead.

* usb: Introduce DesignWare USB3 DRD DriverFelipe Balbi2011-08-231-0/+219
The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.
