This patch splits the PCI portion of ohci-hcd out into its own separate driver module, called ohci-pci. The major point of difficulty lies in ohci-pci's many vendor- and device-specific workarounds. Some of them have to be applied before calling ohci_start() some after, which necessitates a fair amount of code motion. The other platform drivers require much smaller changes. The complete sb800_prefetch() function moved to ohci-q.c,because its only related to ohci-pci driver. USB_OHCI_HCD_PCI symbol no longer dependence on STB03xxx, PPC_MPC52xx and USB_OHCI_HCD_PPC_OF that's what removed. V2: - few specific content of pci related code in ohci_pci_start function has been moved to ohci_pci_reset and rest of the generic code is written in ohci_start of ohci-hcd.c file. V3: - ohci_restart() has been called in ohci_pci_reset() function for to reset the ohci pci. V4: -sb800_prefetch() moved to ohci-q.c,because its only related to ohci-pci. -no longer _creating_ CONFIG_USB_OHCI_PCI,creating CONFIG_USB_OHCI_HCD_PCI. -overrides renamed with pci_override,its giving proper meaning. V5: -sb800_prefetch() moved to pci-quirks.c,because its only related to pci. V6: -sb800_prefetch() function has been moved to pci-quirks.c made as separate patch in 2/3. -Most of the generic ohci pci changes moved in 2/3 patch,now this is complete ohci-pci separation patch. V7: -Unrelated include file has been removed from ohci.h file. V8: -USB_OHCI_HCD_PCI symbol does not dependence on STB03xxx, PPC_MPC52xx and USB_OHCI_HCD_PPC_OF.

Note that this changes is part of separating the ohci pci host controller driver from ohci-hcd host code. This contains : -Moved sb800_prefetch() function from ohci-pci.c to pci-quirks.c file and EXPORTed, this is part of the effort to move the ohci pci related code to generic pci code. -Passed "device" argument instead of "ohci_hcd" in sb800_prefetch() function to avoid extra include file in pci-quirks.c. V2: -Passed "device" argment instead of "pci_dev", then we use to_pci_dev() to get the "pci_dev" structure.

This patch prepares ohci-hcd for being split up into a core library and separate platform driver modules. A generic ohci_hc_driver structure is created, containing all the "standard" values, and a new mechanism is added whereby a driver module can specify a set of overrides to those values. In addition the ohci_restart(),ohci_suspend() and ohci_resume() routines need to be EXPORTed for use by the drivers. Added ohci_setip(() and ohci_start() routine for to start the generic controller rather than each having its own idiosyncratic approach. This allow to clean duplicated code in most of SOC driver In V2: -ohci_hcd_init() ohci_run() and ohci_stop() are not made non-static. -Adds the ohci_setup() and ohci_start() routine. In V3: -purpose of ohci_setup() and ohci_start() function description written in the patch description. -ohci_init() are not made non-static but now called beginning of the ohci_restart(). -ohci_run() signature change reverted back. -unrelated changes removed. -duplicate comment line removed. -inline ohci_suspend() and ohci_resume() is not needed so removed from ohci.h file. In V4: -ohci-init() EXPORTed because it is called by all bus glue modules. -ohci-setup() removed from 1/2 added into 2/2 patch. In V5: -Again ohci_setup() is added and EXPORTed because to replace the ohci_init() from all bus glues. -ohci_init() is not made non-static function. In V6: -ohci_init() call is removed from ohci_quirk_nec_worker(), because it is already called in ohci_restart(). In V8: -ohci_hcd_init() is called by ohci_setup() to make generic ohci initialization in all ohci drivers.

The isochronous scheduling logic in ohci-hcd has a bug. The calculation for skipping TDs that are too late should be carried out only in the !URB_ISO_ASAP case. When URB_ISO_ASAP is set, the URB is pushed back so that none of the TDs are too late, which would cause the calculation to overflow. The patch also fixes the calculation to avoid overflow in the case where the frame value wraps around. This should be applied to -stable kernels going back to 3.8.

Commits c44b2250 (UHCI: implement new semantics for URB_ISO_ASAP) and 6a41b4d3 (OHCI: implement new semantics for URB_ISO_ASAP) increased the latency for isochronous URBs in uhci-hcd and ohci-hcd respectively to 2 milliseconds, in an attempt to avoid underruns. It turns out that not only was this unnecessary -- 1-ms latency works okay -- it also causes problems with certain application loads such as real-time audio. This patch changes the latency for both drivers back to 1 ms. This should be applied to -stable kernels going back to 3.8.

Like the EHCI driver, OHCI supports a large number of different platform glue drivers by directly including them, which causes problems with conflicting macro definitions in some cases. As more ARM architecture specific back-ends are required to coexist in a single build, we should split those out into separate drivers. Unfortunately, the infrastructure for that is still under development, so to give us more time, this uses a separate *_PLATFORM_DRIVER macro for each ARM specific OHCI backend, just like we already do on PowerPC and some of the other ARM platforms. In linux-3.10, only the SPEAr and CNS3xxx back-ends would actually conflict without this patch, but over time we would get more of them, so this is a way to avoid having to patch the driver every time it breaks. We should still split out all back-ends into separate loadable modules, but that work is only needed to improve code size and cleanliness after this patch, not for correctness. While we're here, this fixes the incorrectly sorted error path for the OMAP1 and OMAP3 backends to ensure we always unregister the exact set of drivers that were registered before erroring out.

Problems with NVIDIA's OHCI host controllers persist. After looking carefully through the spec, I finally realized that when a controller is reset it then automatically goes into a SUSPEND state in which it is completely quiescent (no DMA and no IRQs) and from which it will not awaken until the system puts it into the OPERATIONAL state. Therefore there's no need to worry about controllers being in the RESET state for extended periods, or remaining in the OPERATIONAL state during system shutdown. The proper action for device initialization is to put the controller into the RESET state (if it's not there already) and then to issue a software reset. Similarly, the proper action for device shutdown is simply to do a software reset. This patch (as1499) implements such an approach. It simplifies initialization and shutdown, and allows the NVIDIA shutdown-quirk code to be removed.

This patch (as1467) removes the last usages of hcd->state from usbcore. We no longer check to see if an interrupt handler finds that a controller has died; instead we rely on host controller drivers to make an explicit call to usb_hc_died(). This fixes a regression introduced by commit 9b37596a (USB: move usbcore away from hcd->state). It used to be that when a controller shared an IRQ with another device and an interrupt arrived while hcd->state was set to HC_STATE_HALT, the interrupt handler would be skipped. The commit removed that test; as a result the current code doesn't skip calling the handler and ends up believing the controller has died, even though it's only temporarily stopped. The solution is to ignore HC_STATE_HALT following the handler's return. As a consequence of this change, several of the host controller drivers need to be modified. They can no longer implicitly rely on usbcore realizing that a controller has died because of hcd->state. The patch adds calls to usb_hc_died() in the appropriate places. The patch also changes a few of the interrupt handlers. They don't expect to be called when hcd->state is equal to HC_STATE_HALT, even if the controller is still alive. Early returns were added to avoid any confusion.

This patch moves the AMD PLL quirk code in OHCI/EHCI driver to pci-quirks.c, and exports the functions to be used by xHCI driver later. AMD PLL quirk disable the optional PM feature inside specific SB700/SB800/Hudson-2/3 platforms under the following conditions: 1. If an isochronous device is connected to OHCI/EHCI/xHCI port and is active; 2. Optional PM feature that powers down the internal Bus PLL when the link is in low power state is enabled. Without AMD PLL quirk, USB isochronous stream may stutter or have breaks occasionally, which greatly impair the performance of audio/video streams. Currently AMD PLL quirk is implemented in OHCI and EHCI driver, and will be added to xHCI driver too. They are doing similar things actually, so move the quirk code to pci-quirks.c, which has several advantages: 1. Remove duplicate defines and functions in OHCI/EHCI (and xHCI) driver and make them cleaner; 2. AMD chipset information will be probed only once and then stored. Currently they're probed during every OHCI/EHCI initialization, move the detect code to pci-quirks.c saves the repeat detect cost; 3. Build up synchronization among OHCI/EHCI/xHCI driver. In current code, every host controller enable/disable PLL only according to its own status, and may enable PLL while there is still isoc transfer on other HCs. Move the quirk to pci-quirks.c prevents this issue.
