Subject: [PATCH 0/2] Add a quirk in xhci-plat for parent nodes to specify no
 64 bit support

From: Naveen Kumar M <mnkumar@...gle.com>

This patch aims to expose the XHCI_NO_64BIT_SUPPORT flag to the parent
nodes of xhci for clients to specify if they can not support 64 bit DMA
memory pointers. This issue was observed with a Google SoC that uses
a DWC3 controller where the virtual address's higher order bits are
truncated

  dt-bindings: usb: add no-64-bit-support property
