Subject: [PATCH v4 17/18] arm64: dts: qcom: qrb5165-rb5: Switch on TCPM usb-role-switching for usb_1
Date: Sat, 18 Mar 2023 12:18:27 +0000	[thread overview]
Message-ID: <20230318121828.739424-18-bryan.odonoghue@linaro.org> (raw)
In-Reply-To: <20230318121828.739424-1-bryan.odonoghue@linaro.org>

Switch on usb-role-switching for usb_1 via TCPM. We need to declare
usb-role-switch in &usb_1 and associate with the remote-endpoint in TCPM
which provides the necessary signal.
