Subject: [PATCH 5/5] arm64: allwinner: h6: enable USB3 port on Pine H64
Date:   Mon,  7 May 2018 23:18:17 +0800
Message-Id: <20180507151817.55663-6-icenowy@aosc.io>

Precedence: bulk

Pine H64 board have a USB3 port, which is connected to the USB3 pins of
the H6 SoC, and the 5V power supply is controlled via GPIO (shared with
the power USB ports).

Enable this port.
