* USB: OMAP: ISP1301 needs USB_PHYArnd Bergmann2013-04-251-1/+1
| | | | | | | | | | | | | | | | The Kconfig entry for USB_OMAP unconditionally selects USB_ISP1301, which is now only visible when USB_PHY is also enabled. This adds an appropriate dependency and enables USB_PHY in the omap1 defconfig, avoiding these build warnings: warning: (USB_OHCI_HCD && USB_OMAP) selects ISP1301_OMAP which has unmet direct dependencies (USB_SUPPORT && USB_PHY && I2C && ARCH_OMAP_OTG) Also fix a Makefile typo while we're at it.

* usb: phy: tegra: don't call into tegra-ehci directlyArnd Bergmann2013-04-231-4/+9
| | | | | | | | | | | | | | | | | | | | | | | | Both phy-tegra-usb.c and ehci-tegra.c export symbols used by the other one, which does not work if one of them or both are loadable modules, resulting in an error like: drivers/built-in.o: In function `utmi_phy_clk_disable': drivers/usb/phy/phy-tegra-usb.c:302: undefined reference to `tegra_ehci_set_phcd' drivers/built-in.o: In function `utmi_phy_clk_enable': drivers/usb/phy/phy-tegra-usb.c:324: undefined reference to `tegra_ehci_set_phcd' drivers/built-in.o: In function `utmi_phy_power_on': drivers/usb/phy/phy-tegra-usb.c:447: undefined reference to `tegra_ehci_set_pts' This turns the interface into a one-way dependency by letting the tegra ehci driver pass two function pointers for callbacks that need to be called by the phy driver.

* usb: phy: phy core cannot yet be a moduleArnd Bergmann2013-04-231-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A lot of platform code calls into the usb phy core at the moment, which does not work if it is built as a loadable module. This will hopefully change when those platforms are all converted to DT based probing, but for now, the easiest solution is to change it from "tristate" to "bool". This solves at least these ARM allmodconfig build errors: arch/arm/mach-imx/built-in.o: In function `imx_otg_ulpi_create': arch/arm/mach-imx/ulpi.c:117: undefined reference to `otg_ulpi_create' arch/arm/mach-omap2/built-in.o: In function `usbhs_init_phys': arch/arm/mach-omap2/usb-host.c:652: undefined reference to `usb_bind_phy' arch/arm/mach-omap2/built-in.o: In function `omap_2430sdp_init': arch/arm/mach-omap2/board-2430sdp.c:236: undefined reference to `usb_bind_phy' arch/arm/mach-omap2/built-in.o: In function `omap3_beagle_init': arch/arm/mach-omap2/board-omap3beagle.c:554: undefined reference to `usb_bind_phy' arch/arm/mach-omap2/built-in.o: In function `devkit8000_init': arch/arm/mach-omap2/board-devkit8000.c:596: undefined reference to `usb_bind_phy' arch/arm/mach-omap2/built-in.o: In function `omap_ldp_init': arch/arm/mach-omap2/board-ldp.c:379: undefined reference to `usb_bind_phy' drivers/built-in.o: In function `ab8500_charger_probe': drivers/power/ab8500_charger.c:3629: undefined reference to `usb_get_phy' drivers/power/ab8500_charger.c:3706: undefined reference to `usb_put_phy' drivers/built-in.o: In function `ab8500_charger_remove': drivers/power/ab8500_charger.c:3411: undefined reference to `usb_put_phy' Signed-off-by: Arnd Bergmann <arnd@arndb.de> Acked-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

All of these errors were introduced by recent commits which are in linux-next. f_obex, multi and cdc2 gadget drivers have learned to return a proper error code when something goes wrong. usb_bind_phy() was mistakenly placed into .init.text section which caused Section mismatch warnings and undefined reference compile errors. f_source_sink had a copy-paste error which is now corrected. g_zero got a memory leak plugged. Two defconfigs got fixed to enable the newly introduced CONFIG_USB_PHY.

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.

It does work fine when PHY is powered down though. To work around that we have to poll.

Not doing this will save power when cable is connected but no gadget driver is loaded. This will also have side effect of automatic USB charging no longer working without twl4030_charger driver, because a regulator needed for charging will no longer be enabled, so be sure to enable charger driver if charging is needed.

The same goes for initial state, glue already defaults to "no cable" state, so only bother it if we have VBUS or ID.

Also allowing samsung PHY drivers be built as modules. Signed-off-by: Vivek Gautam <gautam.vivek@samsung.com> Acked-by: Kukjin Kim <kgene.kim@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: phy: isp1301: implement PHY APIFelipe Balbi2013-03-181-0/+59
| | | | | | | | | | | | | | | | | | | | this patch implements ->init() and ->set_vbus() methods for isp1301 transceiver driver. Later patches can now come in order to remove the hackery from ohci-nxp and lpc32xx udc drivers. Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: phy: isp1301: give it a context structureFelipe Balbi2013-03-181-0/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | this patch is a small preparation to fix isp1301 driver so that other platforms can use it. We're defining our private data structure to represent this device and adding the PHY to the PHY list. Later patches will come implementing proper PHY API and removing bogus code from ohci_nxp and lpc32xx_udc drivers. Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: phy: rename all phy drivers to phy-$name-usb.cFelipe Balbi2013-03-1826-25/+25
| | | | | | | | | | | | | | | | this will make sure that we have sensible names for all phy drivers. Current situation was already quite bad with too generic names being used. Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: phy: remove CONFIG_USB_OTG_UTILSFelipe Balbi2013-03-181-23/+0
| | | | | | | | | | | | | | | | | | | | | | | | there are no more users of CONFIG_USB_OTG_UTILS left in tree, we can remove it just fine.

| * usb: phy: make it a menuconfigFelipe Balbi2013-03-182-6/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We already have a considerable amount of USB PHY drivers, making it a menuconfig just prevents us from adding too much churn to USB's menuconfig. While at that, also select USB_OTG_UTILS from this new menuconfig just to keep backwards compatibility until we manage to remove that symbol. Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: phy: move all PHY drivers to drivers/usb/phy/Felipe Balbi2013-03-1818-21/+9821
| | | | | | | | | | | | | | | | | | | | | | | | that's a much more reasonable location for those drivers. It helps us saving drivers/usb/otg/ for when we actually start adding generic OTG code. Also completely delete drivers/usb/otg/ as there's nothing left there. Signed-off-by: Felipe Balbi <balbi@ti.com>
| * usb: phy: convert EXPORT_SYMBOL to EXPORT_SYMBOL_GPLFelipe Balbi2013-03-181-10/+10
| | | | | | | | | | | | | | we only want GPL users for our generic functions, so let's switch over to EXPORT_SYMBOL_GPL. Signed-off-by: Felipe Balbi <balbi@ti.com>
