Subject: [RFC PATCH 2/4] usb: dwc3: host: Always set xhci-snps-quirks
Date: Fri, 03 Jun 2022 19:48:15 -0700	[thread overview]
Message-ID: <3980819b8b7ca377896e0e3de93862f3057694e9.1654310542.git.Thinh.Nguyen@synopsys.com> (raw)
In-Reply-To: <cover.1654310542.git.Thinh.Nguyen@synopsys.com>

Always enable xhci-snps-quirks to use xhci-snps glue extension. The
xhci-snps extension can fine tune xhci driver to better handle Synopsys
DWC_usb3x IPs.
