2015-03-06xhci: Workaround for PME stuck issues in Intel xhciMathias Nyman
The xhci in Intel Sunrisepoint and Cherryview platforms need a driver workaround for a Stuck PME that might either block PME events in suspend, or create spurious PME events preventing runtime suspend. Workaround is to clear a internal PME flag, BIT(28) in a vendor specific PMCTRL register at offset 0x80a4, in both suspend resume callbacks Without this, xhci connected usb devices might never be able to wake up the system from suspend, or prevent device from going to suspend (xhci d3) Cc: <stable@vger.kernel.org> Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2015-03-06xhci: fix reporting of 0-sized URBs in control endpointAleksander Morgado
When a control transfer has a short data stage, the xHCI controller generates two transfer events: a COMP_SHORT_TX event that specifies the untransferred amount, and a COMP_SUCCESS event. But when the data stage is not short, only the COMP_SUCCESS event occurs. Therefore, xhci-hcd must set urb->actual_length to urb->transfer_buffer_length while processing the COMP_SUCCESS event, unless urb->actual_length was set already by a previous COMP_SHORT_TX event. The driver checks this by seeing whether urb->actual_length == 0, but this alone is the wrong test, as it is entirely possible for a short transfer to have an urb->actual_length = 0. This patch changes the xhci driver to rely on a new td->urb_length_set flag, which is set to true when a COMP_SHORT_TX event is received and the URB length updated at that stage. This fixes a bug which affected the HSO plugin, which relies on URBs with urb->actual_length == 0 to halt re-submitting the RX URB in the control endpoint.

2015-02-24xhci: Clear the host side toggle manually when endpoint is 'soft reset'Mathias Nyman
Main benefit of this is to get xhci connected USB scanners to work. Some devices use a clear endpoint halt request as a 'soft reset' even if the endpoint is not halted. This will clear the toggle and sequence on the device side. xHCI however refuses to reset a non-halted endpoint, so instead we need to issue a configure endpoint command on xHCI to clear its host side toggle and sequence, and get it in sync with the device side.

2015-02-24xhci: Allocate correct amount of scratchpad buffersMathias Nyman
Include the high order bit fields for Max scratchpad buffers when calculating how many scratchpad buffers are needed. I'm suprised this hasn't caused more issues, we never allocated more than 32 buffers even if xhci needed more. Either we got lucky and xhci never really used past that area, or then we got enough zeroed dma memory anyway.

2015-02-24usb: XHCI: platform: Move the Marvell quirks after the enabling the clocksMaxime Ripard
The commit 973747928514 ("usb: host: xhci-plat: add support for the Armada 375/38x XHCI controllers") extended the xhci-plat driver to support the Armada 375/38x SoCs, mostly by adding a quirk configuring the MBUS window. However, that quirk was run before the clock the controllers needs has been enabled. This usually worked because the clock was first enabled by the bootloader, and left as such until the driver is probe, where it tries to access the MBUS configuration registers before enabling the clock. Things get messy when EPROBE_DEFER is involved during the probe, since as part of its error path, the driver will rightfully disable the clock. When the driver will be reprobed, it will retry to access the MBUS registers, but this time with the clock disabled, which hangs forever. Fix this by running the quirks after the clock has been enabled by the driver.

2015-01-31USB: add flag for HCDs that can't receive wakeup requests (isp1760-hcd)Alan Stern
Currently the USB stack assumes that all host controller drivers are capable of receiving wakeup requests from downstream devices. However, this isn't true for the isp1760-hcd driver, which means that it isn't safe to do a runtime suspend of any device attached to a root-hub port if the device requires wakeup. This patch adds a "cant_recv_wakeups" flag to the usb_hcd structure and sets the flag in isp1760-hcd. The core is modified to prevent a direct child of the root hub from being put into runtime suspend with wakeup enabled if the flag is set.
