2013-10-15usb-core: disable xhciNikunj A Dadhania1-1/+1
Code still does not support xhci, disable creation of xhci node, as it was causing crash in the quiesce path. Also check if ops pointer is verified before accessing function pointers during usb_hcd_exit. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>

2013-08-21usb: fix various issues found with js2xNikunj A Dadhania4-36/+125
* JS20 exposed various timing related issues that were not apparent in the emulated environment. * Reset the USB Bus * JS20 overrides the frame_interval and periodic_start on setting the controller to USB operational. Reprogram them. * ohci fix the data-toggle bits. * Robust error handling Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-21usb: Use separate in-memory endian swapNikunj A Dadhania3-32/+33
Convert pending in-memory byteswaps to accessors Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-21usb-ohci: collect TDs from done listNikunj A Dadhania2-14/+133
OHCI HC after using the TDs queues them back to hccaDoneHead. Until this event the TDs cannot be reused, as there might be references in the host controller still pending. Recycle all the TDs from the queue and acknowledge it by clearing the WD bit in interrupt status register. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-06usb-ohci: Use proper memory barriers alwaysBenjamin Herrenschmidt1-2/+2
Compiler barriers are not useful for ordering memory accesses. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-08-06usb: Fix a couple of warningsBenjamin Herrenschmidt2-1/+5
Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-08-06usb-ehci: Add ehci handshakeNikunj A Dadhania2-6/+43
After removal of the QTD, the device driver needs to make sure that the host controller is really done with this QTD, and does not have any local/cached copy of this. This is achieved by employing a 3-bit handshake as explained in the echi spec 4.8.2 and Fig 4-10 Also add missing memory barrier. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-06usb: add mb for write accessorsNikunj A Dadhania1-0/+5

2013-08-06usb-ohci: add missing memory barriersNikunj A Dadhania1-0/+8
* Start the control/bulk processing after ed is written * Clear the content of control_head_ed and bulk_head_ed once done using them. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-06usb-ohci: suspend the controller in exit code pathNikunj A Dadhania2-7/+3
Moreover ehci already suspends the controller in the hcd_exit path. So we can remove hc-suspend from the cleanup path. Also, count mechanism is not needed anymore, as quiesce is called only once. Signed-off-by: Nikunj A Dadhania <nikunj@linux.vnet.ibm.com>
2013-08-06usb-ohci: Add a reset when closing the OHCIBenjamin Herrenschmidt1-0/+1
Or it will continue DMA'ing which is not a good idea. On recent qemu's that add proper DMA error handling, it will get into error state. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-08-06usb: Use proper accessors for MMIO and separate in-memory endian swapBenjamin Herrenschmidt3-129/+131
We cannot just access MMIO like that. On KVM for example, this has to be hypercalls. On js2x, we need to use special cache-inhibited loads and stores. We have accessors in cache.h, we just need to use them. However that means that read/write_reg() are no longer suitable for in-memory byteswaps. We need to use the accessors in byteorder.h for that While at it, we also fix the code to use mb() instead of barrier() as a full memory barrier is needed to actually order things. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>
2013-07-25Use a global definition of sync() and mb()Benjamin Herrenschmidt3-12/+9
