From 7db70ebb8e3872bfcfd8e304835d5f86a42d83ec Mon Sep 17 00:00:00 2001 From: Stefan Agner Date: Thu, 9 Mar 2017 12:00:46 -0800 Subject: ARM: dts: imx7-colibri: use pull-down for USBC_DET pin The Standard Colibri pin for Client/Host detection USBC_DET (SODIMM pin 137) is multiplexed on the module with USB_OTG1_VBUS. The USB_OTG1_VBUS pad seems to be pulled low by default and not controllable through pinctrl. When the pin is unconnected on the Carrier board, the pin is at a intermediate voltage level which is not ideal. Pull-down the pin to make sure that the pin is at a defined state by default (low, USB host).
