2017-01-26Merge tag 'usb-for-v4.11' of ↵Greg Kroah-Hartman65-2213/+2296
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next Felipe writes: USB: changes for v4.11 Here's the big pull request for the Gadget API. Again the majority of changes sit in dwc2 driver. Most important changes contain a workaround for GOTGCTL being wrong, a sleep-inside-spinlock fix and the big series of cleanups on dwc2. One important thing on dwc3 is that we don't anymore need gadget drivers to cope with unaligned OUT transfers for us. We have support for appending one extra chained TRB to align transfer ourselves. Apart from these, the usual set of typos, non-critical fixes, etc.
2017-01-26usb: dwc3: host: pass quirk-broken-port-ped property for known broken revisionsFelipe Balbi1-3/+18
dwc3 revisions <=3.00a have a limitation where Port Disable command doesn't work. Set the quirk-broken-port-ped property for such controllers so XHCI core can do the necessary workaround.

2017-01-25usb: xhci: add quirk flag for broken PED bitsFelipe Balbi2-0/+9
Some devices from Texas Instruments [1] suffer from a silicon bug where Port Enabled/Disabled bit should not be used to silence an erroneous device. The bug is so that if port is disabled with PED bit, an IRQ for device removal (or attachment) will never fire. Just for the sake of completeness, the actual problem lies with SNPS USB IP and this affects all known versions up to 3.00a. A separate patch will be added to dwc3 to enabled this quirk flag if version is <= 3.00a.

2017-01-25xhci: detect stop endpoint race using pending timer instead of counter.Mathias Nyman3-18/+11
A counter was used to find out if the stop endpoint completion raced with the stop endpoint timeout timer. This was needed in case the stop ep completion failed to delete the timer as it was running on anoter cpu. The EP_STOP_CMD_PENDING flag was not enough as a new stop endpoint command may be queued between the command completion and timeout function, which would set the flag back. Instead of the separate counter that was used we can detect the race by checking both the STOP_EP_PENDING flag and timer_pending in the timeout function.
