2015-03-23usb: xhci: apply XHCI_AVOID_BEI quirk to all Intel xHCI controllersLu Baolu1-1/+1
When a device with an isochronous endpoint is plugged into the Intel xHCI host controller, and the driver submits multiple frames per URB, the xHCI driver will set the Block Event Interrupt (BEI) flag on all but the last TD for the URB. This causes the host controller to place an event on the event ring, but not send an interrupt. When the last TD for the URB completes, BEI is cleared, and we get an interrupt for the whole URB. However, under Intel xHCI host controllers, if the event ring is full of events from transfers with BEI set, an "Event Ring is Full" event will be posted to the last entry of the event ring, but no interrupt is generated. Host will cease all transfer and command executions and wait until software completes handling the pending events in the event ring. That means xHC stops, but event of "event ring is full" is not notified. As the result, the xHC looks like dead to user. This patch is to apply XHCI_AVOID_BEI quirk to Intel xHC devices. And it should be backported to kernels as old as 3.0, that contains the commit 69e848c2090a ("Intel xhci: Support EHCI/xHCI port switching.").

2015-03-23usb: xhci: handle Config Error Change (CEC) in xhci driverLu Baolu1-1/+8
Linux xHCI driver doesn't report and handle port cofig error change. If Port Configure Error for root hub port occurs, CEC bit in PORTSC would be set by xHC and remains 1. This happends when the root port fails to configure its link partner, e.g. the port fails to exchange port capabilities information using Port Capability LMPs. Then the Port Status Change Events will be blocked until all status change bits(CEC is one of the change bits) are cleared('0') (refer to xHCI spec 4.19.2). Otherwise, the port status change event for this root port will not be generated anymore, then root port would look like dead for user and can't be recovered until a Host Controller Reset(HCRST). This patch is to check CEC bit in PORTSC in xhci_get_port_status() and set a Config Error in the return status if CEC is set. This will cause a ClearPortFeature request, where CEC bit is cleared in xhci_clear_port_change_bit().

Avoid calling set_rate on the fixed rate UTMI/IPLL clock and remove useless IS_ENABLED(CONFIG_COMMON_CLK) tests (all at91 platforms have been moved to the CCF). This patch also fixes a bug introduced by 3440ef1 (ARM: at91/dt: fix USB high-speed clock to select UTMI), which was leaving the usb clock uninitialized and preventing the OHCI driver from setting the usb clock rate to 48MHz. This bug was caused by several things: 1/ usb clock drivers set the CLK_SET_RATE_GATE flag, which means the rate cannot be changed once the clock is prepared 2/ The EHCI driver was retrieving and preparing/enabling the uhpck clock which was in turn preparing its parent clock (the usb clock), thus preventing any rate change because of 1/ Fixes: 3440ef169100 ("ARM: at91/dt: fix USB high-speed clock to select UTMI") Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Acked-by: Nicolas Ferre <nicolas.ferre@atmel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

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 Morgado2-2/+11
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 Nyman3-10/+94
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.

2015-02-24usb: XHCI: platform: Move the Marvell quirks after the enabling the clocksMaxime Ripard1-10/+9
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 Stern1-0/+3
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.

Now that this is DRD, it doesn't make sense to keep it under drivers/usb/host. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-01-27usb: isp1760: Add device controller supportLaurent Pinchart6-5/+1761
The ISP1761 is a dual-mode host and device controller backward compatible on the host side with the ISP1760. Add support for the device controller. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-01-27usb: isp1760: Move PORT1 configuration to core codeLaurent Pinchart2-9/+8
Configuring the mode of operation of port 1 doesn't belong to the HCD code, as it's related to the soon to come UDC support. Move the configuration to core code. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-01-27usb: isp1760: Initialize the bus interface in core codeLaurent Pinchart4-75/+105
Although the corresponding register is part of the HCD register space, processor bus initialization is not specific to the HCD. To prepare for device controller support, move bus interface initialization to core code.

Move core device initialization to a central location in order to share it with the device mode implementation. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2015-01-27usb: isp1760: Reorganize header filesLaurent Pinchart4-220/+251
The isp1760-rhcd.h header contains PTD constants and structures only useful for the HCD implementation. It also contains register definitions that will be needed by common code when implementing support for the ISP1761 device controller, but doesn't contain the isp1760_hcd structure definition that will also be used by common code. Move definitions to the right location and create an isp1760-regs.h to store register definitions. No change other than moving definitions and modifying indentation is performed.
