Merge tag 'usb-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH: "Here is the big patchset of USB and PHY driver updates for 4.13-rc1. On the PHY side, they decided to move files around to "make things easier" in their tree. Hopefully that wasn't a mistake, but in linux-next testing, we haven't had any reported problems. There's the usual set of gadget and xhci and musb updates in here as well, along with a number of smaller updates for a raft of different USB drivers. Full details in the shortlog, nothing really major. All of these have been in linux-next for a while with no reported issues" * tag 'usb-4.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (173 commits) Add USB quirk for HVR-950q to avoid intermittent device resets USB hub_probe: rework ugly goto-into-compound-statement usb: host: ohci-pxa27x: Handle return value of clk_prepare_enable USB: serial: cp210x: add ID for CEL EM3588 USB ZigBee stick usbip: Fix uninitialized variable bug in vhci usb: core: read USB ports from DT in the usbport LED trigger driver dt-bindings: leds: document new trigger-sources property usb: typec: ucsi: Add ACPI driver usb: typec: Add support for UCSI interface usb: musb: compress return logic into one line USB: serial: propagate late probe errors USB: serial: refactor port endpoint setup usb: musb: tusb6010_omap: Convert to DMAengine API ARM: OMAP2+: DMA: Add slave map entries for 24xx external request lines usb: musb: tusb6010: Handle DMA TX completion in DMA callback as well usb: musb: tusb6010_omap: Allocate DMA channels upfront usb: musb: tusb6010_omap: Create new struct for DMA data/parameters usb: musb: tusb6010_omap: Use one musb_ep_select call in tusb_omap_dma_program usb: musb: tusb6010: Add MUSB_G_NO_SKB_RESERVE to quirks usb: musb: Add quirk to avoid skb reserve in gadget mode ...
