Subject: [PATCH 0/2] Add a quirk in xhci-plat for parent nodes to specify no 64 bit support
Date: Tue, 31 Oct 2023 04:40:19 +0000 [thread overview]
Message-ID: <20231031044021.1162403-1-mnkumar@google.com> (raw)
From: Naveen Kumar M <mnkumar@google.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
