* USB: ohci: da8xx: use ohci priv data instead of globalsAxel Haslam2016-11-291-30/+43
| | | | | | | | | | | | | | Instead of global variables, use the extra_priv_size of the ohci driver. We cannot yet move the ocic mask because this is used on the interrupt handler which is registered through platform data and does not have an hcd pointer. This will be moved on a later patch.

Most of the work, by far, is on dwc2 this time (68.2%) with dwc3 a far second (22.5%). The remaining 9.3% are scattered on gadget drivers. The most important changes for dwc2 are the peripheral side DMA support implemented by Synopsys folks and support for the new IOT dwc2 compatible core from Synopsys. In dwc3 land we have support for high-bandwidth, high-speed isochronous endpoints and some non-critical fixes for large scatter lists. Apart from these, we have our usual set of cleanups, non-critical fixes, etc.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | xhci->slot_id is used for providing a way to pass slot id from the command completion handler to the function waiting for completion. It's shared by enumerations of all USB devices connected to an xhci host. Hence, it's a source for possible races. Since we've introduced command structure and the command queue to xhci driver. It's better to move slot_id from xhci_hcd structure to xhci_command structure. Hence the race source is removed.

* | usb: xhci: clean up error_bitmask usageLu Baolu2016-11-142-26/+22Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In xhci_handle_event(), when errors are detected, driver always sets a bit in error_bitmask (one member of the xhci private driver data). That means users have to retrieve and decode the value of error_bitmask in xhci private driver data if they want to know whether those erros ever happened in xhci_handle_event(). Otherwise, those errors are just ignored silently. This patch cleans up this by replacing the setting of error_bitmask with the kernel print functions, so that users can easily check and report the errors happened in xhci_handle_event().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | mostly refactoring and code cleanup. while handling transfer events we used to check the return value of various functions to see if we can give back the URB. Turns out the only case when those return values are set are when finish_td() notices we are completing the last td in the URB. give back the urb directly in finish_td() instead. Only functional change is that we now increase the event ring dequeue pointer in sowtware after giving back the URB. This should not matter as we are in hardware interrupt context and the time when writing the new event ring dequeue to hardware remains the same. Hardware is the only one that can put event TRBs on the event ring. Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
