From: Naveen Kumar M <mnkumar@xxxxxxxxxx> 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. Resending due to missing out some reviewers/maintainers in the original patch.
