Subject: [PATCH 1/2] arm64: dts: qcom: sm8250: describe HS signals properly
Date: Fri, 22 Mar 2024 13:58:16 +0200	[thread overview]
Message-ID: <20240322-typec-fix-sm8250-v1-1-1ac22b333ea9@linaro.org> (raw)
In-Reply-To: <20240322-typec-fix-sm8250-v1-0-1ac22b333ea9@linaro.org>

The OF graph should describe physical signals. There is no 'role switch'
signal between Type-C connector and the DWC3 USB controller. Instead
there is a HighSpeed signal lane between DWC3 controller and the USB-C
connector. Rename endpoints in accordance to that (this follows the
example lead by other plaforms, including QRB2210 RB1, QRB4210 RB2 and
all PMIC GLINK platforms).
