From e732f6d26eeab94a4988a556951bbc015b0c3d16 Mon Sep 17 00:00:00 2001 From: Alexander Kurz Date: Tue, 29 May 2018 06:20:20 +0000 Subject: [PATCH] ARM: dts: imx6qdl-wandboard: enable USB OTG Enable USB OTG (dual-role) on the Wandboard. Note, that the USB_OTG_VBUS current is quite limited due to a 22R resistor in the power line. Hence, the overcurrent signal of 1A will never be triggered on this board.
