[PATCH 4.18 104/145] ARM: dts: am57xx-idk: Enable dual role for USB2 port

From: Greg Kroah-Hartman
Date: Fri Sep 07 2018 - 17:18:48 EST


4.18-stable review patch. If anyone has any objections, please let me know.

------------------

From: Roger Quadros <rogerq@xxxxxx>

commit 5f3cc16483d40bbc609a828511ff851296fc62b6 upstream.

Dual-role support was added in v4.12. We should be using
it for USB2 port on the am57xx-idk.
