* usb: ehci: fix deadlock when threadirqs option is usedStanislaw Gruszka2014-02-261-3/+10
| | | | | | | | | | | | | ehci_irq() and ehci_hrtimer_func() can deadlock on ehci->lock when threadirqs option is used. To prevent the deadlock use spin_lock_irqsave() in ehci_irq(). This change can be reverted when hrtimer callbacks become threaded.

| | | | | | | | | | | | | | ENDPTFLUSH and ENDPTPRIME registers are set by software and clear by hardware. There is a bit for each endpoint. When we are setting a bit for an endpoint we should make sure we do not touch other endpoint bit. There is a race condition if the hardware clear the bit between the read and the write in hw_write.

It's likely the last round of fixes for this merge window. All patches have soaked for a long time and have all been tested in real HW. The most interesting fixes are a fix for enumeration of superspeed hubs when MUSB is acting as host, and a remote-wakeup fix also on MUSB. Signed-of-by: Felipe Balbi <balbi@ti.com>

| * usb: phy: msm: fix compilation errors when !CONFIG_PM_SLEEPJosh Cartwright2014-02-201-31/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Both the PM_RUNTIME and PM_SLEEP callbacks call into the common msm_otg_{suspend,resume} routines, however these routines are only being built when CONFIG_PM_SLEEP. In addition, msm_otg_{suspend,resume} also depends on msm_hsusb_config_vddcx(), which is only built when CONFIG_PM_SLEEP. Fix the CONFIG_PM_RUNTIME, !CONFIG_PM_SLEEP case by changing the preprocessor conditional, and moving msm_hsusb_config_vddcx(). While we're here, eliminate the CONFIG_PM conditional for setting up the dev_pm_ops. This address the following errors Russell King has hit doing randconfig builds: drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_suspend': drivers/usb/phy/phy-msm-usb.c:1691:2: error: implicit declaration of function 'msm_otg_suspend' drivers/usb/phy/phy-msm-usb.c: In function 'msm_otg_runtime_resume': drivers/usb/phy/phy-msm-usb.c:1699:2: error: implicit declaration of function 'msm_otg_resume' Cc: Ivan T.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix possible NULL pointer dereference introduced in commit 219580e (usb: f_fs: check quirk to pad epout buf size when not aligned to maxpacketsize) In cases we do wait with: wait_event_interruptible(epfile->wait, (ep = epfile->ep)); for endpoint to be enabled, functionfs_bind() has not been called yet and epfile->ffs->gadget is still NULL and the automatic variable 'gadget' has been initialized with NULL at the point of its definition. Later on it is used as a parameter to: usb_ep_align_maybe(gadget, ep->ep, len) which in turn dereferences it. This patch fixes it by moving the actual assignment to the local 'gadget' variable after the potential waiting has completed.

These bits might be changed by the controller during resume operation and so will be different than what they were during suspend. e.g. SUSPENDM bit is set by software during USB global suspend but automatically cleared by the controller during remote wakeup or during resume. Setting this bit back while restoring context causes undesired behaviour. i.e. Babble interrupt is generated and USB is broken.

* | USB: EHCI: add delay during suspend to prevent erroneous wakeupsAlan Stern2014-02-181-4/+22
|/ | | | | | | | | | | | | | | | | | | | | | High-speed USB connections revert back to full-speed signalling when the device goes into suspend. This takes several milliseconds, and during that time it's not possible to tell reliably whether the device has been disconnected. On some platforms, the Wake-On-Disconnect circuitry gets confused during this intermediate state. It generates a false wakeup signal, which can prevent the controller from going to sleep. To avoid this problem, this patch adds a 5-ms delay to the ehci_bus_suspend() routine if any ports have to switch over to full-speed signalling. (Actually, the delay was already present for devices using a particular kind of PHY power management; the patch merely causes the delay to be used more widely.)

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | xHCI 1.0 hosts have a set of requirements on how to align transfer buffers on the endpoint rings called "TD fragment" rules. When the ax88179_178a driver added support for scatter gather in 3.12, with commit 804fad45411b48233b48003e33a78f290d227c8 "USBNET: ax88179_178a: enable tso if usb host supports sg dma", it broke the device under xHCI 1.0 hosts. Under certain network loads, the device would see an unexpected short packet from the host, which would cause the device to stop sending ethernet packets, even through USB packets would still be sent. Commit 35773dac5f86 "usb: xhci: Link TRB must not occur within a USB payload burst" attempted to fix this. It was a quick hack to partially implement the TD fragment rules. However, it caused regressions in the usb-storage layer and userspace USB drivers using libusb. The patches to attempt to fix this are too far reaching into the USB core, and we really need to implement the TD fragment rules correctly in the xHCI driver, instead of continuing to wallpaper over the issues. Disable arbitrarily-aligned scatter-gather in the xHCI driver for 1.0 hosts. Only the ax88179_178a driver checks the no_sg_constraint flag, so don't set it for 1.0 hosts. This should not impact usb-storage or usbfs behavior, since they pass down max packet sized aligned sg-list entries (512 for USB 2.0 and 1024 for USB 3.0).

* usb-storage: enable multi-LUN scanning when neededAlan Stern2014-02-042-1/+9
| | | | | | | | | | | | | | | | | | | | | | People sometimes create their own custom-configured kernels and forget to enable CONFIG_SCSI_MULTI_LUN. This causes problems when they plug in a USB storage device (such as a card reader) with more than one LUN. Fortunately, we can tell fairly easily when a storage device claims to have more than one LUN. When that happens, this patch asks the SCSI layer to probe all the LUNs automatically, regardless of the config setting. The patch also updates the Kconfig help text for usb-storage, explaining that CONFIG_SCSI_MULTI_LUN may be necessary.

| | | | | | | | | | | | | | | | | | | The move from the staging tree to the main tree exposed a longstanding memory corruption bug in the dwc2 driver. The reordering of the driver initialization caused the dwc2 driver to corrupt the initialization data of the sdhci driver on the Raspberry Pi platform, which made the bug show up. The error is in calling to_usb_device(hsotg->dev), since ->dev is not a member of struct usb_device. The easiest fix is to just remove the offending code, since it is not really needed.

Hi Greg, Here's four patches for 3.14. One of them adds an xHCI host quirk, and the other three of them fix regressions introduced in 3.14. One regression causes USB 3.0 Link PM to be enabled on all xHCI hosts (even those that may not support it), which causes some USB 3.0 devices to not enumerate. A second regression causes some xHCI hosts that don't support 64-bit addressing to stop responding to commands and die. Note, these patches don't fix the recent usbfs regression that was caused by commit 35773dac5f862cb1c82ea151eba3e2f6de51ec3e "usb: xhci: Link TRB must not occur within a USB payload burst".

Unfortunately, that's not the case. The xHCI driver relies on knowledge of the host hardware scheduler to calculate the LPM U1/U2 timeout values, and it only sets lpm_capable to one for Intel host controllers (that have the XHCI_LPM_SUPPORT quirk set).

They are fixes and cleanups mostly, as usual, with a couple of new features in the mix. The most visible change is probably that we will create struct acpi_device objects (visible in sysfs) for all devices represented in the ACPI tables regardless of their status and there will be a new sysfs attribute under those objects allowing user space to check that status via _STA. Consequently, ACPI device eject or generally hot-removal will not delete those objects, unless the table containing the corresponding namespace nodes is unloaded, which is extremely rare. Also ACPI container hotplug will be handled quite a bit differently and cpufreq will support CPU boost ("turbo") generically and not only in the acpi-cpufreq driver. Specifics: - ACPI core changes to make it create a struct acpi_device object for every device represented in the ACPI tables during all namespace scans regardless of the current status of that device. In accordance with this, ACPI hotplug operations will not delete those objects, unless the underlying ACPI tables go away. - On top of the above, new sysfs attribute for ACPI device objects allowing user space to check device status by triggering the execution of _STA for its ACPI object. From Srinivas Pandruvada. - ACPI core hotplug changes reducing code duplication, integrating the PCI root hotplug with the core and reworking container hotplug. - ACPI core simplifications making it use ACPI_COMPANION() in the code "glueing" ACPI device objects to "physical" devices. - ACPICA update to upstream version 20131218. This adds support for the DBG2 and PCCT tables to ACPICA, fixes some bugs and improves debug facilities. From Bob Moore, Lv Zheng and Betty Dall. - Init code change to carry out the early ACPI initialization earlier.

This way the role of this callback is more clear and the implementation of it can be more straightforward. Update all of the users of struct acpi_bus_type (PCI, PNP/ACPI and USB) to reflect the structure change. Signed-off-by: Rafael J.

First of all, <acpi/acpi.h>, <acpi/acpi_bus.h> and <acpi/acpi_drivers.h> should not be included directly from any files that are built for CONFIG_ACPI unset, because that generally leads to build warnings about undefined symbols in !CONFIG_ACPI builds. For CONFIG_ACPI set, <linux/acpi.h> includes those files and for CONFIG_ACPI unset it provides stub ACPI symbols to be used in that case. Second, there are ordering dependencies between those files that always have to be met. Namely, it is required that <acpi/acpi_bus.h> be included prior to <acpi/acpi_drivers.h> so that the acpi_pci_root declarations the latter depends on are always there. And <acpi/acpi.h> which provides basic ACPICA type declarations should always be included prior to any other ACPI headers in CONFIG_ACPI builds. That also is taken care of including <linux/acpi.h> as appropriate.

The largest part of this is a conversion of device registration for some renesas shmobile/sh devices over to use resources. This has required coordination with the corresponding arch/sh changes, and we've agreed to merge the arch/sh changes through our tree. Added in this branch is support for Trusted Foundations secure firmware, which is what is used on many of the commercial Nvidia Tegra products that are in the market, including the Nvidia Shield. The code is local to arch/arm at this time since it's uncertain whether it will be shared with arm64 longer-term, if needed we will refactor later.
