Subject: [PATCH 1/2] usb: host: xhci-plat: Add quirk-no-64-bit-support
Date: Tue, 31 Oct 2023 04:40:20 +0000 [thread overview]
Message-ID: <20231031044021.1162403-2-mnkumar@google.com> (raw)
In-Reply-To: <20231031044021.1162403-1-mnkumar@google.com>
From: Naveen Kumar M <mnkumar@google.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.
