Merge tag 'usb-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH: "Here is the big USB/PHY driver patches for 4.20-rc1 Lots of USB changes in here, primarily in these areas: - typec updates and new drivers - new PHY drivers - dwc2 driver updates and additions (this old core keeps getting added to new devices.) - usbtmc major update based on the industry group coming together and working to add new features and performance to the driver. - USB gadget additions for new features - USB gadget configfs updates - chipidea driver updates - other USB gadget updates - USB serial driver updates - renesas driver updates - xhci driver updates - other tiny USB driver updates All of these have been in linux-next for a while with no reported issues" * tag 'usb-4.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (229 commits) usb: phy: ab8500: silence some uninitialized variable warnings usb: xhci: tegra: Add genpd support usb: xhci: tegra: Power-off power-domains on removal usbip:vudc: BUG kmalloc-2048 (Not tainted): Poison overwritten usbip: tools: fix atoi() on non-null terminated string USB: misc: appledisplay: fix backlight update_status return code phy: phy-pxa-usb: add a new driver usb: host: add DT bindings for faraday fotg2 usb: host: ohci-at91: fix request of irq for optional gpio usb/early: remove set but not used variable 'remain_length' usb: typec: Fix copy/paste on typec_set_vconn_role() kerneldoc usb: typec: tcpm: Report back negotiated PPS voltage and current USB: core: remove set but not used variable 'udev' usb: core: fix memory leak on port_dev_path allocation USB: net2280: Remove ->disconnect() callback from net2280_pullup() usb: dwc2: disable power_down on rockchip devices usb: gadget: udc: renesas_usb3: add support for r8a77990 dt-bindings: usb: renesas_usb3: add bindings for r8a77990 usb: gadget: udc: renesas_usb3: Add r8a774a1 support USB: serial: cypress_m8: remove set but not used variable 'iflag' ...
