Recently we purchased the Rigol DS6104 and when I try to operate it from my Linux pc, everything works well with the default usbtmc driver, except when I want to download a big datachunk like a screenshot. This bitmapfile has a size of 1152054 bytes but I receive a smaller file and no new packets can be read. When I took a look at the driver source, I found this "Rigol quirk" and I added the id of the new DS series oscilloscopes to this list. I compiled it and loaded the new driver and now everything seems to work fine. Signed-off-by: Teunis van Beelen <teuniz@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

This patch fixes an issue that sometimes this controller is not able to complete the Control write status stage. This driver should enable DCPCTR.CCPL and PID_BUF to complete the status stage. However, if this driver detects the ctrl_stage interruption first before the control write data is received, this driver will clear the PID_BUF wrongly in the usbhsf_pio_try_pop(). To avoid this issue, this patch doesn't clear the PID_BUF in the usbhsf_pio_try_pop(). (Since also the privious code doesn't disable the PID_BUF after a control transfer was finished, this patch doesn't have any side efforts.)

This patch fixes an issue for control write. When usbhsf_prepare_pop() is called after this driver called a gadget setup function, this controller doesn't receive the control write data. So, this patch adds a code to clear the fifo for control write in usbhsf_prepare_pop().

Fix USB 3.0 devices lost in NOTATTACHED state after a hub port reset. Dissolve the function hub_port_finish_reset() completely and divide the actions to be taken into those which need to be done after each reset attempt and those which need to be done after the full procedure is complete, and place them in the appropriate places in hub_port_reset(). Also, remove an unneeded forward declaration of hub_port_reset(). Verbose Problem Description: USB 3.0 devices may be "lost for good" during a hub port reset. This makes Linux unable to boot from USB 3.0 devices in certain constellations of host controllers and devices, because the USB device is lost during initialization, preventing the rootfs from being mounted. The underlying problem is that in the affected constellations, during the processing inside hub_port_reset(), the hub link state goes from 0 to SS.inactive after the initial reset, and back to 0 again only after the following "warm" reset. However, hub_port_finish_reset() is called after each reset attempt and sets the state the connected USB device based on the "preliminary" status of the hot reset to USB_STATE_NOTATTACHED due to SS.inactive, yet when the following warm reset is complete and hub_port_finish_reset() is called again, its call to set the device to USB_STATE_DEFAULT is blocked by usb_set_device_state() which does not allow taking USB devices out of USB_STATE_NOTATTACHED state. Thanks to Alan Stern for guiding me to the proper solution and how to submit it.

We used to write the root port state changes in turn for every port, sleeping 20ms after every port state change. Suspended usb2 ports need two state changes, taking minimun 40ms per port. Now instead poll the Port Link State Change (PLC) bit as the state change to U0 will set this bit. Suspended usb2 ports still need the extra 20ms delay, but we now change all the port states at once so we only need to sleep 20ms once all together Signed-off-by: Mathias Nyman <mathias.nyman@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

In the OTG case, the controller might not yet have been added or is removed before the system suspends. Assign xhci->main_hcd during probe to prevent NULL pointer de-reference in xhci_suspend/resume().

The problem seems to be that if a new device is detected while we have already removed the shared HCD, then many of the xhci operations (e.g. xhci_alloc_dev(), xhci_setup_device()) hang as command never completes. I don't think XHCI can operate without the shared HCD as we've already called xhci_halt() in xhci_only_stop_hcd() when shared HCD goes away. We need to prevent new commands from being queued not only when HCD is dying but also when HCD is halted. The following lockup was detected while testing the otg state machine.

In case of non-Isochronous transfers, we don't want to clear DWC3_EP_BUSY flag until XferComplete event. That's because XferInProgress was only enabled so we can recycle TRBs and usb_requests quicker, but there are still other pending requests being transferred. In order to make sure we don't allow for another StartTransfer command while the HW is still processing other transfers, we must keep DWC3_EP_BUSY flag set and this what this patch does.

The sunxi otg phy has a bug where it wrongly detects a high speed squelch when reset on the root port gets de-asserted with a lo-speed device. The workaround for this is to disable squelch detect before de-asserting reset, and re-enabling it after the reset de-assert is done. Add a sunxi specific phy function to allow the sunxi-musb glue to do this.

twl4030_charger currently finds the associated phy using usb_get_phy() which will return the first USB2 phy. If your platform has multiple such phys (as mine does), this is not reliable (and reliably fails on the GTA04). Change to use devm_usb_get_phy_by_node(), having found the node by looking for an appropriately named sibling in device-tree. This makes usb-charging dependent on correct device-tree configuration.

Split the "get phy from device_node" functionality out of "get phy by phandle" so it can be used directly. This is useful when a battery-charger is intimately associated with a particular phy but handled by a separate driver. The charger can find the device_node based on sibling relationships without the need for a redundant declaration in the devicetree description. As a peripheral that gets a phy will often want to register a notifier block, and de-register it later, that functionality is included so the de-registration is automatic.

USB3380 enhanced mode allows GPEP to be used in both IN and OUT directions. However, IN and OUT endpoints must use same USB endpoint address (bEndpointAddress). Fix this by setting the ep_cfg.ep_number during initialization and keep it in net2280_enable() Tested-by: Ricardo Ribalda Delgado <ricardo.ribalda@gmail.com> Signed-off-by: Mian Yousaf Kaukab <yousaf.kaukab@intel.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
