Subject: [PATCH RESEND 1/2] usb: host: xhci-plat: Add quirk-no-64-bit-support
From: Naveen Kumar M <mnkumar@...gle.com>
This patch exposes the existing quirk XHCI_NO_64BIT_SUPPORT so that dwc3
clients can also use this flag. Despite HCCPARAMS1 being set to 1 some
clients may not support 64 bit addressing.
