usb: ohci-at91: fix irq and iomem resource retrieval

2013-12-17T21:22:36Z

When using dt resources retrieval (interrupts and reg properties) there is no predefined order for these resources in the platform dev resources table. Retrieve resources using platform_get_resource and platform_get_irq functions instead of direct resource table entries to avoid resource type mismatch.

usb: phy: fix driver dependencies

2013-12-17T05:31:24Z

both isp1301-omap and fsl_usb2_otg drivers depend on usb_bus_start_enum() which is only defined if CONFIG_USB != n. There is a problem, however, where both those drivers could be statically linked, while CONFIG_USB=m. Fix the problem by fixing driver dependency.

xhci: Limit the spurious wakeup fix only to HP machines

2013-12-10T19:44:39Z

We've got regression reports that my previous fix for spurious wakeups after S5 on HP Haswell machines leads to the automatic reboot at shutdown on some machines. It turned out that the fix for one side triggers another BIOS bug in other side. So, it's exclusive. Since the original S5 wakeups have been confirmed only on HP machines, it'd be safer to apply it only to limited machines. As a wild guess, limiting to machines with HP PCI SSID should suffice. This patch should be backported to kernels as old as 3.12, that contain the commit 638298dc66ea36623dbc2757a24fc2c4ab41b016 "xhci: Fix spurious wakeups after S5 on Haswell".

usb: chipidea: fix nobody cared IRQ when booting with host role

2013-12-09T21:14:12Z

If we connect Male-A-To-Male-A cable between otg-host and host pc, the ci->vbus_active is set wrongly, and cause the controller run at peripheral mode when we load gadget module (ci_udc_start will be run), but the software runs at host mode due to id = 0. The ehci_irq can't handle suspend (USBi_SLI) interrupt which is enabled for peripheral mode, it causes no one will handle irq error.

usb: chipidea: host: Only disable the vbus regulator if it is not NULL

2013-12-09T21:14:12Z

Commit 40ed51a4b (usb: chipidea: host: add vbus regulator control) introduced a smatch complaint because regulator_disable() is called without checking whether ci->platdata->reg_vbus is not NULL.

usb: hub: Use correct reset for wedged USB3 devices that are NOTATTACHED

2013-12-05T01:00:43Z

This patch adds a check for USB_STATE_NOTATTACHED to the hub_port_warm_reset_required() workaround for ports that end up in Compliance Mode in hub_events() when trying to decide which reset function to use. Trying to call usb_reset_device() with a NOTATTACHED device will just fail and leave the port broken. Signed-off-by: Julius Werner Acked-by: Alan Stern Cc: stable Signed-off-by: Greg Kroah-Hartman
