2013-06-11phy-rcar-usb: handle platform dataSergei Shtylyov1-6/+45
Set the USBPCTRL0 register from the passed platform data in rcar_usb_phy_init(); don't reset it to 0 in rcar_usb_phy_shutdown() anymore as that does not make sense. Also, don't allow the driver's probe to succeed when the platform data are not supplied with a device. The patch has been tested on the Marzen and BOCK-W boards.

2013-06-11phy-rcar-usb: correct base addressSergei Shtylyov1-18/+10
The memory region that is used by the driver overlaps EHCI and OHCI register regions for absolutely no reason now -- fix it by adding offset of 0x800 to the base address, changing the register #define's accordingly. This has extra positive effect that we now can use devm_ioremap_resource()... Note that the driver and the SoC code have to be in one patch to keep the code bisectable...

2013-06-11phy-rcar-usb: remove EHCI internal buffer setupSergei Shtylyov1-24/+4
Now that the EHCI internal buffer setup is done by the platform code, we can remove such code from this driver as it never really belonged here. We also no longer need the 2nd memory region now (2nd EHCI controller is simply missing in e.g. R8A7778 SoC). The patch has been tested on the Marzen and BOCK-W boards.

2013-05-30usb: phy: registering Tegra USB PHY as platform driverVenu Byravarasu1-145/+180
Registered Tegra USB PHY as a separate platform driver. To synchronize host controller and PHY initialization, used deferred probe mechanism. As PHY should be initialized before EHCI starts running, deferred probe of Tegra EHCI driver till PHY probe gets completed. Got rid of instance number based handling in host driver. Made use of DT params to get the PHY Pad registers. Signed-off-by: Venu Byravarasu <[email protected]> Signed-off-by: Felipe Balbi <[email protected]>

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.

2013-04-03usb: phy: ab8500-usb: adopt pinctrl supportPatrice Chotard1-0/+24
Amend the ab8500-usb driver to optionally take a pin control handle and set the state of the pins to "default" on ab8500_usb_phy_enable and to "sleep" on ab8500_usb_phy_disable. The pinctrl handle is released on ab8500_usb_phy_disable because USB pins are shared with ab8505_micro_usb_iddet driver.
