* USB: isp1362: better 64bit printf warning fixesLothar Wassmann2010-01-201-2/+2
| | | | | | | | | | | Some hosts that treat the return value of sizeof differently from unsigned long might still hit warnings. So use %zu for sizeof() values. This is a better version of the previous commit b0a9cf297e58721933.

* USB: fix usbstorage for 2770:915d delivers no FATRyan May2010-01-201-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | Resolves kernel.org bug 14914. Remove entry for 2770:915d (usb digital camera with mass storage support) from unusual_devs.h. The fix triggered by the entry causes the file system on the camera to be completely inaccessible (no partition table, the device is not mountable). The patch works, but let me clarify a few things about it. All the patch does is remove the entry for this device from the drivers/usb/storage/unusual_devs.h, which is supposed to help with a problem with the device's reported size (I think). I'm pretty sure it was originally added for a reason, so I'm not sure removing it won't cause other problems to reappear. Also, I should note that this unusual_devs.h entry was present (and activating workarounds) in 2.6.29, but in that version everything works fine. Starting with 2.6.30, things no longer work.

After the device reset and re-configuration, the device and the xHCI host think they are using alternate setting 0 of all interfaces. However, the USB core keeps track of the old state, which may include non-zero alternate settings. It uses intf->cur_altsetting to keep the endpoint sysfs files for the old state across the reset. The bandwidth allocation functions need to know what the xHCI host thinks the current alternate settings are, so original patch set intf->cur_altsetting to the alternate setting 0. This caused duplicate endpoint files to be created. The solution is to not set intf->cur_altsetting before calling usb_set_interface() in usb_reset_and_verify_device(). Instead, we add a new flag to struct usb_interface to tell usb_hcd_alloc_bandwidth() to use alternate setting 0 as the currently installed alternate setting.

* USB: add missing delay during remote wakeupAlan Stern2010-01-203-3/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1330) fixes a bug in khbud's handling of remote wakeups. When a device sends a remote-wakeup request, the parent hub (or the host controller driver, for directly attached devices) begins the resume sequence and notifies khubd when the sequence finishes. At this point the port's SUSPEND feature is automatically turned off. However the device needs an additional 10-ms resume-recovery time (TRSMRCY in the USB spec). Khubd does not wait for this delay if the SUSPEND feature is off, and as a result some devices fail to behave properly following a remote wakeup. This patch adds the missing delay to the remote-wakeup path. It also extends the resume-signalling delay used by ehci-hcd and uhci-hcd from 20 ms (the value in the spec) to 25 ms (the value we use for non-remote-wakeup resumes). The extra time appears to help some devices.

* USB: EHCI & UHCI: fix race between root-hub suspend and port resumeAlan Stern2010-01-202-2/+33
| | | | | | | | | | | | | | | This patch (as1321) fixes a problem with EHCI and UHCI root-hub suspends: If the suspend occurs while a port is trying to resume, the resume doesn't finish and simply gets lost. When remote wakeup is enabled, this is undesirable behavior. The patch checks first to see if any port resumes are in progress, and if they are then it fails the root-hub suspend with -EBUSY.

* USB: EHCI: fix handling of unusual interrupt intervalsAlan Stern2010-01-201-3/+8
| | | | | | | | | | | | | | | | | | | | | | | | | This patch (as1320) fixes two problems related to interrupt-URB scheduling in ehci-hcd. URBs with an interval of 2 or 4 microframes aren't handled. For the time being, the patch reduces to interval to 1 uframe. URBs are constrained to have an interval no larger than 1024 frames by usb_submit_urb(). But some EHCI controllers allow use of a schedule as short as 256 frames; for these controllers we may have to decrease the interval to the actual schedule length. The second problem isn't very significant since few devices expose interrupt endpoints with an interval larger than 256 frames. But the first problem is critical; it will prevent the kernel from working with devices having interrupt intervals of 2 or 4 uframes.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | The constants used to specify ISINK ramp times for WM835x had the wrong shifts so that the on times applied to the off ramp and vice versa. The masks for the bitfields are correct. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Cc: stable@kernel.org Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

| | * | | powerpc: Use scripts/mkuboot.sh instead of 'mkimage'Peter Tyser2009-12-301-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mkuboot.sh provides a basic wrapper for the 'mkimage' utility. Using mkuboot.sh provides clearer error reporting and allows a toolchain to use its own 'mkimage' executable specified by ${CROSS_COMPILE}mkimage. Additionally, this brings PowerPC in line with other architectures which already call mkimage via mkuboot.sh.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We noticed that recent kernels didn't boot on our 1GHz Canyonlands 460EX boards anymore. As it seems, patch 8d165db1 [powerpc: Improve decrementer accuracy] introduced this problem. The routine div_sc() overflows with shift = 32 resulting in this incorrect setup: time_init: decrementer frequency = 1000.000012 MHz time_init: processor frequency = 1000.000012 MHz clocksource: timebase mult[400000] shift[22] registered clockevent: decrementer mult[33] shift[32] cpu[0] This patch now introduces a local div_dc64() version of this function so that this overflow doesn't happen anymore.

I have no idea how this ever worked, and on recent kernels it causes an oops in handle_tape_event() when we access the non-initialised completion.
