[PATCH 2/3] arm64: dts: qcom: sc8180x-primus: Wire up USB Type-C

From: Bjorn Andersson
Date: Mon Jun 12 2023 - 18:15:17 EST


Wire up pmic_glink and the various components of USB Type-C to get
battery status, orientation switching of SuperSpeed USB, as well as
support for external display on the SC8180X Primus reference device.
