+Subject: [PATCH] arm64: dts: qcom: qrb2210-rb1: use USB host mode
+
+The default for the QCM2290 platform that this board is based on is OTG
+mode, however the role detection logic is not hooked up for this board
+and the dwc3 driver is configured to not allow role switching from
+userspace.
+
+Force this board to host mode as this is the preferred usecase until we
+get role switching hooked up.
+
+Fixes: e18771961336 ("arm64: dts: qcom: Add initial QTI RB1 device tree")
