Pull USB/Thunderbolt/PHY driver updates from Greg KH: "Here is the big USB and Thunderbolt and PHY driver updates for 5.6-rc1. With the advent of USB4, "Thunderbolt" has really become USB4, so the renaming of the Kconfig option and starting to share subsystem code has begun, hence both subsystems coming in through the same tree here. PHY driver updates also touched USB drivers, so that is coming in through here as well. Major stuff included in here are: - USB 4 initial support added (i.e. Thunderbolt) - musb driver updates - USB gadget driver updates - PHY driver updates - USB PHY driver updates - lots of USB serial stuff fixed up - USB typec updates - USB-IP fixes - lots of other smaller USB driver updates All of these have been in linux-next for a while now (the usb-serial tree is already tested in linux-next on its own before merged into here), with no reported issues" [ Removed an incorrect compile test enablement for PHY_EXYNOS5250_SATA that causes configuration warnings - Linus ] * tag 'usb-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (207 commits) Doc: ABI: add usb charger uevent usb: phy: show USB charger type for user usb: cdns3: fix spelling mistake and rework grammar in text usb: phy: phy-gpio-vbus-usb: Convert to GPIO descriptors USB: serial: cyberjack: fix spelling mistake "To" -> "Too" USB: serial: ir-usb: simplify endpoint check USB: serial: ir-usb: make set_termios synchronous USB: serial: ir-usb: fix IrLAP framing USB: serial: ir-usb: fix link-speed handling USB: serial: ir-usb: add missing endpoint sanity check usb: typec: fusb302: fix "op-sink-microwatt" default that was in mW usb: typec: wcove: fix "op-sink-microwatt" default that was in mW usb: dwc3: pci: add ID for the Intel Comet Lake -V variant usb: typec: tcpci: mask event interrupts when remove driver usb: host: xhci-tegra: set MODULE_FIRMWARE for tegra186 usb: chipidea: add inline for ci_hdrc_host_driver_init if host is not defined usb: chipidea: handle single role for usb role class usb: musb: fix spelling mistake: "periperal" -> "peripheral" phy: ti: j721e-wiz: Fix build error without CONFIG_OF_ADDRESS USB: usbfs: Always unlink URBs in reverse order ...

usb: dwc3: gadget: Remove END_TRANSFER delay

2020-01-15T09:39:23+00:00

We had a 100us delay to synchronize the END_TRANSFER command completion before giving back requests to the function drivers. Now, the controller driver can handle cancelled TRBs with the requests' cancelled_list and it can also wait until the END_TRANSFER completion before starting new transfers. Synchronization can simply base on the controller's command completion interrupt. The 100us delay is no longer needed. Remove this arbitrary delay.

usb: dwc3: gadget: Delay starting transfer

2020-01-15T09:39:23+00:00

If the END_TRANSFER command hasn't completed yet, then don't send the START_TRANSFER command. The controller may not be able to start if that's the case. Some controller revisions depend on this. See commit 76a638f8ac0d ("usb: dwc3: gadget: wait for End Transfer to complete"). Let's only send START_TRANSFER command after the END_TRANSFER command had completed.

usb: dwc3: gadget: Check END_TRANSFER completion

2020-01-15T09:39:23+00:00

While the END_TRANSFER command is sent but not completed, any request dequeue during this time will cause the driver to issue the END_TRANSFER command. The driver needs to submit the command only once to stop the controller from processing further. The controller may take more time to process the same command multiple times unnecessarily. Let's add a flag DWC3_EP_END_TRANSFER_PENDING to check for this condition.

usb: dwc3: turn off VBUS when leaving host mode

VBUS should be turned off when leaving the host mode. Set GCTL_PRTCAP to device mode in teardown to de-assert DRVVBUS pin to turn off VBUS power.

2020-01-15T09:39:19+00:00

DCTL.ULSTCHNGREQ is a write-only field. When doing a read-modify-write to DCTL, the driver must make sure that there's no unintended link state change request from whatever is read from DCTL.ULSTCHNGREQ.
