As we proceed to untangle the dependencies between platform code and driver code, the amount of changes in this category is fortunately shrinking, for 3.11 we have 16 branches here and 101 non-merge changesets, the majority of which are for the stedma40 dma engine driver used in the ux500 platform. Cleaning up that code touches multiple subsystems, but gets rid of the dependency in the end. The mailbox code moved out from mach-omap2 to drivers/mailbox is an intermediate step and is still omap specific at the moment. Patches exist to generalize the subsystem and add other drivers with the same API, but those did not make it for 3.11." * tag 'drivers-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (101 commits) crypto: ux500: use dmaengine_submit API crypto: ux500: use dmaengine_prep_slave_sg API crypto: ux500: use dmaengine_device_control API crypto: ux500/crypt: add missing __iomem qualifiers crypto: ux500/hash: add missing static qualifiers crypto: ux500/hash: use readl on iomem addresses dmaengine: ste_dma40: Declare memcpy config as static ARM: ux500: Remove mop500_snowball_ethernet_clock_enable() ARM: ux500: Correct the EN_3v3 regulator's on/off GPIO ARM: ux500: Provide a AB8500 GPIO Device Tree node gpio: rcar: fix gpio_rcar_of_table gpio-rcar: Remove #ifdef CONFIG_OF around OF-specific sections gpio-rcar: Reference core gpio documentation in the DT bindings clk: exynos5250: Add enum entries for divider clock of i2s1 and i2s2 ARM: dts: Update Samsung I2S documentation ARM: dts: add clock provider information for i2s controllers in Exynos5250 ARM: dts: add Exynos audio subsystem clock controller node clk: samsung: register audio subsystem clocks using common clock framework ARM: dts: use #include for all device trees for Samsung pinctrl: s3c24xx: use correct header for chained_irq functions ...

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.

In particular, the urb->start_frame field should always be set by the driver; it isn't an input parameter. The simplest way to accomplish this is to treat all URBs as though the URB_ISO_ASAP flag was set. This won't give the right behavior when an underrun occurs, but I don't know enough about the musb driver to handle that case. Unfortunately, I have no way to test this change.

This leads to error in handling the present URB. Fix this by making the use_sg flag URB specific.

* | musb: fix context save over suspend.NeilBrown2013-05-171-0/+6
|/ | | | | | | | | | | | | | | | | | | | | | | | | | It is possible that the musb device will be runtime-active (not suspended) when system suspend happens. In particular, usb_suspend() will have called choose_wakeup() which might have called pm_runtime_resume(). In that case, after system-resume, the state of the device will be 'active', but the state of the registers will have been lost (if off_mode is enabled). So we need to save_context in musb_suspend (if runtime state is active), and restore_context on resume. This effectively reverts 5d193ce8 (usb: musb: PM: fix context save/restore in suspend/resume path) and adds a rest to avoid saving/restoring context if device is already runtime suspended.

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | MUSB controller cannot work in DMA mode with misaligned buffers, switching in PIO mode. HCD core has hooks that allow to override the default DMA mapping and unmapping routines for host controllers that have special DMA requirements, such as alignment constraints. It is observed that work in PIO mode is slow and it's better to align buffers properly before passing them to MUSB This increased throughput 80->120 MBits/s over musb@omap4 with USB Gigabit Ethernet adapter attached.

| | | | | | | | | | | | | | | | | | | | | | | | On some platform configurations (like OMAP3+twl4030) it's the platform code that enables VBUS, not OTG transceiver, so call vbus platform callback instead, it will then call the transceiver if needed.
