2010-05-20USB: EHCI: fix controller wakeup flag settings during suspendAlan Stern5-71/+145
This patch (as1380) fixes a bug in the wakeup settings for EHCI host controllers. When the controller is suspended, if it isn't enabled for remote wakeup then we have to turn off all the port wakeup flags. Disabling PCI PME# isn't good enough, because some systems (Intel) evidently use alternate wakeup signalling paths. In addition, the patch improves the handling of the Intel Moorestown hardware by performing various power-up and power-down delays just once instead of once for each port (i.e., the delays are moved outside of the port loops). This requires extra code, but the total delay time is reduced. There are also a few additional minor cleanups.

2010-05-20USB: ehci-omap: Fix resume failures after bus suspendAnand Gadiyar1-0/+14
An undocumented "feature" in the OMAP3 EHCI controller causes suspended ports to be taken out of suspend when the USBCMD.Run/Stop bit is cleared (this bit is normally cleared when ehci_bus_suspend is called). This "feature" breaks suspend-resume if the root-hub is allowed to suspend. (The controller thinks it is in resume, and the PHY thinks it is still in suspend). There is an undocumented register bit that can be used to disable this feature and restore normal behavior. Set this bit so suspend-resume can work normally. Tested on OMAP3 SDPs with the NXP ISP1504 and NXP ISP1703 PHYs. Signed-off-by: Anand Gadiyar <gadiyar@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2010-05-20USB: fix interface runtime-PM settingsAlan Stern1-6/+11
This patch (as1379) reworks the logic for handling USB interface runtime-PM settings -- hopefully it's right this time! The problem is that when a driver is unbound or binding fails, runtime PM for the interface always gets disabled. But pm_runtime_disable() nests, so it shouldn't be called unless the interface was previously enabled for runtime PM.

2010-05-20USB: ohci: Add Kconfig entries for ohci-omap3Anand Gadiyar2-2/+44
On OMAP systems, we have two different OHCI controllers. The legacy one is present in OMAP1/2 chips, and the newer one comes bundled as a companion to the EHCI controller on OMAP3 and newer chips. We may have multi-omap configurations where OMAP2 and OMAP3 support may be enabled in the same kernel, and need a mechanism to keep both drivers around. This patch adds a Kconfig entry for each of these drivers.

Add support for the OHCI controller present in OMAP3 and newer chips. The code is mostly based off the ehci-omap.c driver. Some of it is common to both drivers and will eventually need to be factored out to platform init files. In its current state, the driver cannot co-exist with the ehci-omap driver, and this will be fixed in later versions. The second driver to be loaded will overwrite settings made by the other. For now, this driver should allow the few users of OMAP3 OHCI to get going.

2010-05-20USB: isp1760: Soften DW3 X/transaction error bit handlingAnton Vorontsov1-4/+3
There were some reports[1] of isp1760 USB driver malfunctioning with high speed devices, noticed on Blackfin and PowerPC targets. These reports indicated that the original Philips 'pehcd'[2] driver worked fine. We've noticed the same issue with an ARM RealView platform. This happens under load (with only some mass storage devices, not all, just as in another report[3]): error bit is set in DW3 error bit is set in DW3 error bit is set in DW3 usb 1-1.2: device descriptor read/64, error -32 It appears that the 'pehcd' driver checks the X bit only if the transaction is halted (H bit), otherwise the error is so far insignificant. The ISP176x chips were modeled after EHCI, and EHCI spec says (thanks to Alan Stern for pointing out): "Transaction errors cause the status field to be updated to reflect the type of error, but the transaction continues to be retried until the Active bit is set to 0. When the error counter reaches 0, the Halt bit is set and the Active bit is cleared." So, just as the original Philips driver, isp1760 must report the error only if the transaction error and the halt bits are set.

This is a patch that makes sure that the device ID data (idVendor, idProduct and bcdDevice) are assigned to the descriptor in the cdev structure *before* the composite gadget starts binding. This allows the composite driver, and all the composite functions it uses, access to that data. In one of the composite functions we created, we needed to register an input device and wanted to use the idVendor, idProduct and bcdDevice codes to properly initialize the id field of the input device. We could not do that because the idVendor, idProduct and bcdDevice values were only set in the cdec structure *after* the composite->bind(cdev) call.
