Subject: [PATCH 3/7] arm64: dts: qcom: msm8996: Strictly limit USB2 host to USB2 speeds
Date: Tue, 25 May 2021 22:02:41 +0200 [thread overview]
Message-ID: <20210525200246.118323-3-konrad.dybcio@somainline.org> (raw)
In-Reply-To: <20210525200246.118323-1-konrad.dybcio@somainline.org>
As the name implies, the USB2 controller should only operate at
USB2 speeds. Make sure it does just that by pinning it to USB
High-Speed (USB2) mode.
