Merge tag 'usb-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb
Pull USB/PHY updates from Greg KH: "Here is the big set of USB and PHY driver patches for 5.2-rc1 There is the usual set of: - USB gadget updates - PHY driver updates and additions - USB serial driver updates and fixes - typec updates and new chips supported - mtu3 driver updates - xhci driver updates - other tiny driver updates Nothing really interesting, just constant forward progress. All of these have been in linux-next for a while with no reported issues. The usb-gadget and usb-serial trees were merged a bit "late", but both of them had been in linux-next before they got merged here last Friday" * tag 'usb-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb: (206 commits) USB: serial: f81232: implement break control USB: serial: f81232: add high baud rate support USB: serial: f81232: clear overrun flag USB: serial: f81232: fix interrupt worker not stop usb: dwc3: Rename DWC3_DCTL_LPM_ERRATA usb: dwc3: Fix default lpm_nyet_threshold value usb: dwc3: debug: Print GET_STATUS(device) tracepoint usb: dwc3: Do core validation early on probe usb: dwc3: gadget: Set lpm_capable usb: gadget: atmel: tie wake lock to running clock usb: gadget: atmel: support USB suspend usb: gadget: atmel_usba_udc: simplify setting of interrupt-enabled mask dwc2: gadget: Fix completed transfer size calculation in DDMA usb: dwc2: Set lpm mode parameters depend on HW configuration usb: dwc2: Fix channel disable flow usb: dwc2: Set actual frame number for completed ISOC transfer usb: gadget: do not use __constant_cpu_to_le16 usb: dwc2: gadget: Increase descriptors count for ISOC's usb: introduce usb_ep_type_string() function usb: dwc3: move synchronize_irq() out of the spinlock protected block ...
