The logic of the handling Missed Service Error Events was pretty confusing as we were checking the same condition several times. In addition, it caused compiler warning since the compiler could not figure out that event_trb is actually unused in case we are skipping current TD. Fix that by rearranging "skip" condition checks, and factor out skip_isoc_td() so that it is called explicitly. Signed-off-by:

There were some places that compared port_speed == -1 where port_speed is a u8. This doesn't work unless we cast the -1 to u8. Some places did it correctly. Instead of using -1 directly, I've created a DUPLICATE_ENTRY define which does the cast and is more descriptive as well. Signed-off-by:

The driver did not take the zero flag in the USB request. If the request length is the same as the endpoint's maxpacket, an additional ZLP with no data has to be transmitted. The method used here is inspired to what is done in fsl_udc_core.c (and pxa27x_udc.c and at91_udc.c) where this is supported. There already was a discussion about this topic with people from Keymile, and I propose here a better implementation: http://thread.gmane.org/gmane.linux.usb.general/38951Signed-off-by:

There was an unlock missing on the error path. Also I did a small cleanup by changing ep->dev->lock for just dev->lock. They're the same lock, but dev->lock is shorter and that's how it is used for the spin_unlock_irqrestore() call. Signed-off-by:

It turns out that this function calls pci_get_device under a spin_lock with irqs disabled, but the pci_get_device function is only allowed in preemptible context. This patch fixes the warning by making all data-structure modifications on temporal storage and commiting this back into the visible structure at the end. While at it, this patch also moves the pci_dev_put calls out of the spinlocks because this function might sleep too. Signed-off-by:

This patch (as1458) fixes a problem affecting ultra-reliable systems: When hardware failover of an EHCI controller occurs, the data structures do not get released correctly. This is because the routine responsible for removing unused QHs from the async schedule assumes the controller is running properly (the frame counter is used in determining how long the QH has been idle) -- but when a failover causes the controller to be electronically disconnected from the PCI bus, obviously it stops running. The solution is simple: Allow scan_async() to remove a QH from the async schedule if it has been idle for long enough _or_ if the controller is stopped. Signed-off-by:

DMA mode 1 data corruption anomaly on Blackfin systems. This issue is specific to the Blackfin silicon as the bug appears to be related to the connection of the musb ip to the bus/dma fabric. Data corruption when using USB DMA mode 1. (Issue manager 17-01-0105) DMA mode 1 allows large size transfers to generate a single interrupt at the end of the entire transfer. The transfer is split up in packets of length specified in the Maximum Packet Size field for that endpoint. If the transfer size is not an integer multiple of the Maximum Packet Size, a short packet will be present at the end of the transfer. Under certain conditions this packet may be corrupted in the USB FIFO. Workaround: Use DMA mode 1 to transfer (n* Maximum Packet Size) and schedule DMA mode 0 to transfer the short packet. As an example if your transfer size is 33168 bytes and Maximum Packet Size equals 512, schedule [33168 - (33168 mod 512)] in DMA mode 1 and the remainder (33168 mod 512) in DMA mode 0. Signed-off-by:

Due to the recent changes to musb's glue layers, we can't compile musb-hdrc as a module - compilation will break due to undefined symbol musb_debug. In order to fix that, we need a big re-work of the debug support on the MUSB driver. Because that would mean a lot of new code coming into the -rc series, it's best to defer that to next merge window and for now just disable module support for MUSB. Once we get the refactor of the debugging support done, we can simply revert this patch and things will go back to normal again. Cc: stable@kernel.org # v2.6.38 Signed-off-by: -
