Subject: [PATCH 3/3] ARM: dts: sun8i: s3: switch PineCube to use OHCI/EHCI only
Date: Sun, 22 Nov 2020 08:40:11 +0800
Message-ID: <20201122004011.1957325-2-icenowy@aosc.io> (raw)
In-Reply-To: <20201122003841.1957034-1-icenowy@aosc.io>

The PineCube board features a USB Type-A connector connected to the
SoC's USB pins.

As this is not designed for being used as a USB device, disable OTG
controller and route USB to OHCI/EHCI fixedly.
