git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb 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 ...

2020-01-15usb: dwc3: gadget: Remove END_TRANSFER delayThinh Nguyen1-13/+5
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.

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.

2020-01-15usb: dwc3: gadget: Check END_TRANSFER completionThinh Nguyen3-2/+9
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.

Fix up inconsistent usage of upper and lowercase letters in "Samsung" and "Exynos" names. "SAMSUNG" and "EXYNOS" are not abbreviations but regular trademarked names. Therefore they should be written with lowercase letters starting with capital letter.

2019-08-30usb: dwc3: gadget: Workaround Mirosoft's BESL checkThinh Nguyen1-2/+12
While testing our host system using Microsoft's usb stack against our gadget for various BESL values, we found an issue with their usb stack when the recommended baseline BESL value is 0 (125us) or when the deep BESL is 1 or less. The Windows host will issue a usb reset immediately after it receives the extended BOS descriptor and the enumeration will fail after a few attempts. To keep compatibility with Microsoft's host usb stack, let's workaround this issue by using the recommended baseline BESL of 1 (or 150us) and clamp the deep BESL value within 2 to 15.

2019-08-28usb: dwc3: gadget: Set BESL config parameterThinh Nguyen1-0/+10
When operating with LPM signals, the controller asserts the deep low-power signal (utmi_l1_suspend_n) to the phy when the BESL value of the LPM token is equal to or greater than DCTL.HIRD_Thres[3:0] (and with DCTL.HIRD_Thres[4] set). Otherwise, the shallow low-power signal (utmi_sleep_n) is asserted. Set the recommended deep BESL equal to the controller's DCTL.HIRD_Thres[3:0] setting, and set the baseline BESL to 0 for the shallow low-power signal. This maximizes the opportunity for L1 residency and optimizes power savings. Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>

2019-08-28usb: dwc3: st: Add of_dev_put() in probe functionNishka Dasgupta1-0/+1
In function st_dwc3_probe, variable child_pdev takes the value returned by of_find_device_by_node, which gets a device pointer but does not put it. If child_pdev is not put before the probe function returns, it may cause a reference leak. Hence put child_pdev after its last usage. Issue found with Coccinelle.

2019-08-28usb: dwc3: st: Add of_node_put() before return in probe functionNishka Dasgupta1-3/+6
The local variable child in the function st_dwc3_probe takes the return value of of_get_child_by_name, which gets a node and does not put it. If the function returns without releasing child, this could cause a memory error. Hence put child as soon as there is no more use for it. Also create a new label, err_node_put, just before label undo_softreset; so that err_node_put puts child. In between initialisation of child and its first put, modify all statements that go to undo_softreset to now go to err_node_put instead, from where they can fall through to undo_softreset.

2019-08-28usb: dwc3: don't set gadget->is_otg flagRoger Quadros1-1/+0
This reverts commit 6a4290cc28be1 ("usb: dwc3: gadget: set the OTG flag in dwc3 gadget driver.") We don't yet support any of the OTG mechanisms (HNP/SRP/ADP) and are not setting gadget->otg_caps, so don't set gadget->is_otg flag. If we do then we end up publishing a OTG1.0 descriptor in the gadget descriptor which causes device enumeration to fail if we are connected to a host with CONFIG_USB_OTG enabled.

2019-08-09usb: dwc3: remove generic PHYs forwarding for XHCI deviceMarek Szyprowski1-18/+4
Commit 08f871a3aca2 ("usb: dwc3: host: convey the PHYs to xhci") added forwarding of the generic PHYs from DWC3 core to the instantiated XHCI-plat device. However XHCI(-plat) driver never gained support for generic PHYs, thus the lookup added by that commit is never used. In meantime the commit d64ff406e51e ("usb: dwc3: use bus->sysdev for DMA configuration") incorrectly changed the device used for creating lookup, making the lookup useless and generic PHYs inaccessible from XHCI device. However since commit 178a0bce05cb ("usb: core: hcd: integrate the PHY wrapper into the HCD core") USB HCD already handles generic PHYs acquired from the HCD's 'sysdev', which in this case is DWC3 core device. This means that creating any custom lookup entries for XHCI driver is no longer needed and can be simply removed.
