instead of having each user of generic phy find out about its own resources and pass it to the core layer, have th core layer itself figure that out. It's as simple as moving a piece of code around.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.13 Final conversions to configfs for mass storage, acm_ms, and multi gadgets. MUSB should now work out of the box on AM335x-based boards (beagle bone white and black) with DMA thanks to Sebastian's work. We can now enable VERBOSE_DEBUG on builds of drivers/usb/gadget/ by selecting CONFIG_USB_GADGET_VERBOSE. s3c-hsotg got quite a few non-critical fixes but also learned a few new tricks (isochronous transfers, multi count support). The Marvel USB3 Controller driver got a memory leak fix. devm_usb_get_phy() learned not to return NULL, ever. Other than these patches, we have the usual set of cleanups ranging from removal of unnecessary *_set_drvdata() to using SIMPLE_DEV_PM_OPS. Signed-of-by: Felipe Balbi <balbi@ti.com>

Used the generic PHY framework API to create the PHY. For powering on and powering off the PHY, power_on and power_off ops are used. Once the MUSB OMAP glue is adapted to the new framework, the suspend and resume ops of usb phy library will be removed. Also twl4030-usb driver is moved to drivers/phy/. However using the old usb phy library cannot be completely removed because otg is intertwined with phy and moving to the new framework completely will break otg.

Move probe out of __init section and don't use platform_driver_probe which cannot be used with deferred probing. Since commit e9354576 ("gpiolib: Defer failed gpio requests by default") and 04bf3011 ("regulator: Support driver probe deferral") this driver might return -EPROBE_DEFER if a gpio_request or regulator_get fails.

Use the wrapper functions for getting and setting the driver data using platform_device instead of using dev_{get,set}_drvdata() with &of->dev, so we can directly pass a struct platform_device.

2013-08-27usb: phy: fix build breakageAnatolij Gustschin
Commit 94ae9843 (usb: phy: rename all phy drivers to phy-$name-usb.c) renamed drivers/usb/phy/otg_fsm.h to drivers/usb/phy/phy-fsm-usb.h but changed drivers/usb/phy/phy-fsm-usb.c to include not existing "phy-otg-fsm.h" instead of new "phy-fsm-usb.h". This breaks building: ... drivers/usb/phy/phy-fsm-usb.c:32:25: fatal error: phy-otg-fsm.h: No such file or directory compilation terminated. make[3]: *** [drivers/usb/phy/phy-fsm-usb.o] Error 1 This commit also missed to modify drivers/usb/phy/phy-fsl-usb.h to include new "phy-fsm-usb.h" instead of "otg_fsm.h" resulting in another build breakage: ...

Randy reported this |drivers/usb/phy/phy-am335x-control.c:45:3: error: implicit declaration |of function '__WARN' [-Werror=implicit-function-declaration] and left it as an excercice to figure out that this happens only with CONFIG_BUG=n. As a fix I replace it with WARN_ON(). And there is a space before return so fix this, too.

2013-08-13Merge tag 'usb-for-v3.12' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: usb: patches for v3.12 merge window All patches here have been pending on linux-usb and sitting in linux-next for a while now. The biggest things in this tag are: DWC3 learned proper usage of threaded IRQ handlers and now we spend very little time in hardirq context. MUSB now has proper support for BeagleBone and Beaglebone Black. Tegra's USB support also got quite a bit of love and is learning to use PHY layer and generic DT attributes. Other than that, the usual pack of cleanups and non-critical fixes follow.

Stephen Rothwell reported that this driver does not compile on PowerPC due to this missing include. One could argue why this driver is enabled on PowerPC in the first place but it sure isn't wrong to include headers for used function instead of to rely that they sneak in.

2013-08-12usb: phy: tegra: Program new PHY parametersTuomas Tynkkynen
The Tegra30 TRM recommends configuration of certain PHY parameters for optimal quality. Program the following registers based on device tree parameters: - UTMIP_XCVR_HSSLEW: HS slew rate control. - UTMIP_HSSQUELCH_LEVEL: HS squelch detector level - UTMIP_HSDISCON_LEVEL: HS disconnect detector level. These registers exist in Tegra20, but programming them hasn't been necessary, so these parameters won't be set on Tegra20 to keep the device trees backward compatible. Additionally, the UTMIP_XCVR_SETUP parameter can be set from fuses instead of a software-programmed value, as the optimal value can vary between invidual boards. The boolean property nvidia,xcvr-setup-use-fuses can be used to enable this behaviour.
