Message

NXP imx8MPlus integrates 2 indentical dwc3 3.30b IP with additional wakeup
logic to support low power, this wakeup logic has a separated interrupt
which can generate events with suspend clock(32K), due to SoC integration
limitation, 64bit address can't be supported for host controller, but the
xhci capability register HCCPARAMS1 AC64 bit is 1, so introduce a new
property snps,xhci-dis-64bit-support-quirk to enable existing quirk
XHCI_NO_64BIT_SUPPORT for OF platforms.

  dt-bindings: usb: dwc3: add property to disable xhci 64bit support
  usb: host: xhci-plat: add quirk for XHCI_NO_64BIT_SUPPORT
