Subject: [PATCH v2 4/4] arm64: dts: imx8mp-iota2: Enable the USB Type-C port

From: Petr Benes <petr.benes@...ft.com>

Enable the USB Type-C port with the Diodes PI5USB30213A port controller.
The port supports dual role data but can operate only in source power role
and PD is not supported.

v2:
- Use typec instead of tcpc.
- Drop unneeded status.
