The driver calls pci_set_mwi to enable memory-write-invalidate when it is initialized, but does not call pci_clear_mwi when it is removed. Many other drivers calls pci_clear_mwi when pci_set_mwi is called, such as r8169, 8139cp and e1000. This patch adds a function "ehci_pci_remove" to remove the pci driver. This function calls pci_clear_mwi and usb_hcd_pci_remove, which can fix the problem. Signed-off-by:

The driver calls ehci_mem_init to allocate memory resources. But these resources are not freed when ehci_halt fails. This patch adds "ehci_mem_cleanup" in error handling code to fix this problem. Signed-off-by:

Registering usb_hcd_platform_shutdown to be called during shutdown. This is a generic function that performs the generic host stack's shutdown. It ensures that USB operations do not continue while kexec boots a new kernel. Signed-off-by:

The default value for the 'transceiver select' field of the PORTSC register may not always be correct. Previously the phy-msm-usb driver would do this for us, but since ehci-msm can now be instantiated standalone without any PHY driver, the register needs to be explicitly initialized to ULPI mode to properly communicate with the PHY. This is not readily apparent, as firmware or bootloader code also happen to pre-initialize this for us. However, it can manifest when performing a driver unbind/rebind as follows: cd /sys/bus/platform/drivers/msm_hsusb_host echo QCOM8040:00 > unbind echo QCOM8040:00 > bind The EHCI core executes a controller reset as part of this, and as a result the register in question would revert to its default state and must be re-initialized properly. Furthermore this may be useful in the future when adding PM suspend/resume support. Signed-off-by:

Allow the EHCI MSM driver to probe against an ACPI enumerated device with ID QCOM8040. Signed-off-by:
-
Jack Pham authored
Currently the EHCI MSM driver has a hard dependency to be created by an OTG layer, namely the phy-msm-usb driver. In some cases or board configurations we want to allow the EHCI host to be instantiated without OTG capability. Instead, relax the dependency on having an OTG PHY being present and call usb_add_hcd() directly. Signed-off-by:

This splits one big probing function into two smaller ones. The main one is now responsible for the generic stuff: allocating memory & enabling power using GPIO. The new one contains code that is specific to the USB 2.0 bcma core. This will allow adding support for the USB 3.0 bcma core (handling XHCI) in the future. Signed-off-by:

Having "bool ohci" argument in bcma_hcd_create_pdev function limited it to support two cases only (OHCI and EHCI) and put too much logic in it. Lets make caller pass all required data. This adds few extra arguments to the function call but will allow us to reuse this code and handle more cases in the future (e.g. add XHCI support). Signed-off-by:

kbasename() helper is dedicated to find a last part of the filename or pathname. USB core uses open-coded variant of that helper. Replace some lines of code by kbasename() call. The current users do not have trailing slash and we are on the safe side to make such change. I dig a history of the code under question up and found the patch [1] that brought it along with the same to tty layer. The check for trailing slash looks like copy'n'paste thing and I consider it as redundant.

usb 3.1 extend the hub get-port-status request by adding different request types. the new request types return 4 additional bytes called extended port status, these bytes are returned after the regular portstatus and portchange values. The extended port status contains a speed ID for the currently used sublink speed. A table of supported Speed IDs with details about the link is provided by the hub in the device descriptor BOS SuperSpeedPlus device capability Sublink Speed Attributes. Support this new request. Ask for the extended port status after port reset if hub supports USB 3.1. If link is running at SuperSpeedPlus set the device speed to USB_SPEED_SUPER_PLUS Signed-off-by:

If we detect that there is nothing to do just set the flag and do not check if it was already set before. Races really do not matter. If the flag is set by any code then the shepherd will start dealing with the situation and reenable the vmstat workers when necessary again. Since commit 0eb77e98 ("vmstat: make vmstat_updater deferrable again and shut down on idle") quiet_vmstat might update cpu_stat_off and mark a particular cpu to be handled by vmstat_shepherd. This might trigger a VM_BUG_ON in vmstat_update because the work item might have been sleeping during the idle period and see the cpu_stat_off updated after the wake up. The VM_BUG_ON is therefore misleading and no more appropriate. Moreover it doesn't really suite any protection from real bugs because vmstat_shepherd will simply reschedule the vmstat_work anytime it sees a particular cpu set or vmstat_update would do the same from the worker context directly. Even when the two would race the result wouldn't be incorrect as the counters update is fully idempotent. Reported-by:
