2011-08-23USB: usbtest: use URB_ZERO_PACKET for BULK-OUT transfersSebastian Andrzej Siewior
Executing | testusb -a -c 1 -t 3 -v 421 -s 2048 does not complete on the gadget side. g_zero enqueues a 4096 bytes long buffer. The host sends 2048bytes which is a multiple of wMaxPacketSize (either 64 or 512 bytes). The host is done with sending data but the gadget waits for more. Since the protocol does not include transfer-length-field sending a terminating zero packet seems the only way out.

2011-08-23usb/isp1760: Clear TT buffer on interrupted low & full speed transfersArvid Brodin
When a low or full speed urb in progress is unlinked (or some other error occurs), the buffer in the transaction translator (part of the hub) might end up in an inconsistent state. This can make all further low and full speed transactions fail, unless the buffer is cleared. The bug can be seen when running the usbtest unlink tests as "set altsetting to 0 failed, -110", and gets fixed by this patch.

2011-08-22s3c-hsudc: Fix possible nullpointer dereference during probeHeiko Stübner
The usb-interrupt is requested before the endpoints are initalised. If an interrupt happens in the time between request_irq and the init of the endpoint-data (as seen on the Qisda ESx00 ebook-platforms), it is therefore possible for the interrupt handler to access endpoint- data before its creation resulting in a null-pointer dereference. This patch simply moves the irq request below the endpoint init. Signed-off-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-08-22usb: Introduce DesignWare USB3 DRD DriverFelipe Balbi
The DesignWare USB3 is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI) configurations. Several other parameters can be configured like amount of FIFO space, amount of TX and RX endpoints, amount of Host Interrupters, etc. The current driver has been validated with a virtual model of version 1.73a of that core and with an FPGA burned with version 1.83a of the DRD core. We have support for PCIe bus, which is used on FPGA prototyping, and for the OMAP5, more adaptation (or glue) layers can be easily added and the driver is half prepared to handle any possible configuration the HW engineer has chosen considering we have the information on one of the GHWPARAMS registers to do runtime checking of certain features. More runtime checks can, and should, be added in order to make this driver even more flexible with regards to number of endpoints, FIFO sizes, transfer types, etc. While this supports only the device side, for now, we will add support for Host side (xHCI - see the updated series Sebastian has sent [1]) and OTG after we have it all stabilized.

2011-08-22USB: EHCI: remove usages of hcd->stateAlan Stern
This patch (as1483) improves the ehci-hcd driver family by getting rid of the reliance on the hcd->state variable. It has no clear owner and it isn't protected by the usual HCD locks. In its place, the patch adds a new, private ehci->rh_state field to record the state of the root hub. Along the way, the patch removes a couple of lines containing redundant assignments to the state variable. Also, the QUIESCING state simply gets changed to the RUNNING state, because the driver doesn't make any distinction between them.

2011-08-22usb/isp1760: Use polling instead of SOF interrupts to fix Errata 2Arvid Brodin
Errata 2 for the isp1760 explains that the chip sometimes does not issue interrupts when an ATL (bulk or control) transfer is completed. There are several issues with the current work-around (SOF interrupts) for this: 1) It seems the chip sometimes does not even set the done bit for a completed transfer, in which case SOF interrupts does not solve the problem since we still check the done map to find out which transfer descriptors to handle. 2) The above point seems to happen only when ATL and SOF interrupts are enabled at the same time. However, disabling ATL interrupts increases the latency between transfer completion and handling. This is very noticeable in the testusb suite, which take several minutes more to run with ATL interrupts disabled. This patch removes the code to switch on SOF interrupts, and instead use a kernel timer to periodically check for "old" descriptors that have their VALID and ACTIVE flags unset, indicating completion, thus avoiding the dependency on the chip's done map (and SOF interrupts) to find transfers affected by this HW bug.

2011-08-22usb_storage: Don't freeze in usb-stor-scanSeth Forshee
Scanning cannot be run during suspend or hibernation, but if usb-stor-scan freezes another thread waiting on scanning to complete may fail to freeze. However, if usb-stor-scan is left freezable without ever actually freezing then the freezer will wait on it to exit, and threads waiting for scanning to finish will no longer be blocked. One problem with this approach is that usb-stor-scan has a delay to wait for devices to settle (which is currently the only point where it can freeze). To work around this we can request that the freezer send a fake signal when freezing, then use interruptible sleep to wake the thread early when freezing happens. To make this happen, the following changes are made to usb-stor-scan: * Use set_freezable_with_signal() instead of set_freezable() to request a fake signal when freezing * Use wait_event_interruptible_timeout() instead of wait_event_freezable_timeout() to avoid freezing Signed-off-by: Seth Forshee <seth.forshee@canonical.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

Prior to Ivybridge, the GFX_MODE would default to 0x800, meaning that MI_FLUSH would flush the TLBs in addition to the rest of the caches indicated in the MI_FLUSH command. However starting with Ivybridge, the register defaults to 0x2800 out of reset, meaning that to invalidate the TLB we need to use PIPE_CONTROL.

Currently, error handling code in this function calls the function sata_dwc_port_stop, but this function has essentially no effect if hsdevp has not been stored in ap, which is the case throughout this function. The only effect is to print a debugging message including ap->print_id. The code is rewritten to not call sata_dwc_port_stop, but instead to jump to a local label that prints the original error message and the print_id information. In the case where hsdevp has been already allocated (but not yet stored in ap), this value is freed as well.

2011-08-16regmap: using module facilities requires module.hStephen Rothwell
Commit b33f9cbd67ba ("regmap: Specify a module license") added a MODULES_LICENSE to this file without adding an include of module.h. module.h should have been included anyway, since this file has EXPORT_SYMBOLs as well. With the pending module.h split up, this would probably have caused build problems.
