2011-05-02USB: s3c-hsotg: Fix hang up after resetAnton Tikhomirov1-5/+0
When File Storage gadget receives SET CONFIGURATION request it tries to cancel all pending transfers. If some request is in progress, gadget waits for its completion. This commit allows gadget to dequeue invalid requests in progress left after reset.

2011-05-02USB: s3c-hsotg: Fix stall condition processingAnton Tikhomirov1-31/+111
The following should be done for requests after endpoint stall condition is cleared: 1) 'in progress' request (if any) should be completed since Tx FIFO was flushed; 2) next request from queue (if any) should be started. This commit does that. Additionally set/clear stall condition code is fixed.

2011-05-02USB: fsl_udc_core: support device mode of MPC5121E DR USB ControllerAnatolij Gustschin2-31/+112
Extend the FSL UDC driver to support MPC5121E DR USB Controller operation in device mode. Add MPC5121E specific init/uninit at probe and remove and isolate system interface register accesses when running on MPC5121E SoC, as these registers are not available on this platform. This patch relies on previous patch for supporting big endian registers and descriptors access in the FSL UDC driver. Additionally support endpoint FIFO status operation by providing appropriate callback in endpoint ops structure. Also flush cache for the req buffer used for GetStatus reply. Without this, the correct reply to an endpoint GetStatus is written to 'req', but doesn't make it out to the USB bus since the buffer hasn't been flushed. This would cause the USBCV Halt Endpoint test to fail (according to changelog in Freescale LTIB driver code).

2011-05-02USB: fsl_udc_core: prepare for SoCs with BE registers and descriptorsAnatolij Gustschin2-25/+100
On some SoCs, the USB controller registers and descriptors can be big or little endian, depending on the version of the chip. In order to be able to run the same kernel binary on different versions of an SoC, the BE/LE decision must be made at run time. Provide appropriate register and descriptor accessors which are configurable at run time using the configuration flags from fsl_usb2_platform_data data structure. This is in preparation for adding support for MPC5121E DR USB2 Controller to the FSL UDC driver.

As a result no USB platform devices for MPH DR USB controller will be created at run time and no probing will be done in the fsl_udc_core driver.

2011-04-29USB: add queued-unlinks test case to usbtest driverAlan Stern1-2/+118
This patch (as1452b) adds a new test case to the usbtest driver. Test 24 exercises the unlink-from-queue pathways in the host. It queues a user-specified number of bulk-OUT URBs of user-specified size, unlinks the fourth- and second-from-last URBs in the queue, and then waits to see if all the URBs complete in the expected way (except of course that the unlinked URBs might complete normally, if they weren't unlinked soon enough). This new test has confirmed the existence of a bug in the ehci-hcd driver, to be fixed by a separate patch.

2011-04-29usb: renesas_usbhs: don't re-allocation pipe bufferKuninori Morimoto1-3/+17
Because pipe buffer allocation is very picky and difficult, current renesas_usbhs driver is not caring pipe re-allocation. In this situation, driver will create new pipe without caring old pipe if "usbhsg_ep_enable" is called after "usbhsg_ep_disable" on current driver. This mean the limited pipe and buffer will be used as waste. But it is possible to re-use same buffer to same pipe. By this patch, driver will initialize pipe when it detected new connection or new gadget, and doesn't try re-allocation for same pipe in above case.

2011-04-29USB: documentation update for the pre_reset methodAlan Stern2-5/+9
This patch (as1459) updates the documentation for the pre_reset method in struct usb_driver. When a driver is notified of an impending reset, it must cancel all outstanding I/O and not start any new I/O until it has been notified that the reset is complete. As far as I know, most existing drivers that implement pre_reset do this now. The major exceptions appear to be the SpeedTouch and CDC-WDM drivers.
