Merge tag 'usb-5.6-rc1' of 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 ...
