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. Signed-off-by:

UDC driver does not need to generate reply to host if request is delivered to gadget. This is gadget's responsibility. This commit fixes that. Signed-off-by:

This commit does the following: 1) clears all pending interrupts before unmasking; 2) clears interrupts as soon as possible to avoid missing next coming that may occur during handling; 3) removes ineffective interrupt cleaning code. Signed-off-by:

Slightly reworked and cleaned up driver from Freescale LTIB for MPC5121E. The driver has been ported to the current kernel, proc interface "/proc/driver/fsl_usb2_otg" has been replaced by sysfs interface. Signed-off-by:

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). Signed-off-by:

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. Signed-off-by:

When only FSL USB gadget driver is selected in the kernel configuration the MPH DR OF driver for creation of FSL USB platform devices from device tree won't be built. 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. Add an entry to the Makefile to build the MPH DR OF platform driver if CONFIG_USB_FSL_MPH_DR_OF is defined. Signed-off-by:

The usb_create_sysfs_intf_files() function always returned zero even if it failed to create sysfs fails. Since this is a desired behaviour there is no need to return return code at all. This commit changes function's return type (form int) to void. Signed-off-by:

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. Signed-off-by:

the_controller is allocated in dummy_hcd_probe() and is NULL if the allocation failed. The probe function of the udc driver is dereferencing this pointer and fault. Alan Stern suggested to abort the dummy_hcd driver probing so the module is not loaded. The is abort-on-error has been also added to the udc driver. Signed-off-by:

Current renesas_usbhs was designed to save power when USB is not connected. And it assumed platform uses callback to notify connection/disconnection by external interrupt. But some SuperH / platform board doesn't have such feature. This patch adds autonomy mode which detect USB connection/disconnection by internal interrupt. But power will be always ON when autonomy mode is selected. Signed-off-by:

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. Signed-off-by:

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. Signed-off-by:
