Subject: [PATCH v2 6/7] arm64: dts: qcom: sc8180x-primus: Enable the two MP
 USB ports

From: Bjorn Andersson <quic_bjorande@...cinc.com>

The SC8180X Primus comes with an AUX card with two USB ports, fed by the
two multiport ports.

Enable the involved nodes and define two always-on regulators to enable
VBUS for these ports.
