From 1f0cbe2b52b1ed7832a2f9c48950522f7b0fb6e8 Mon Sep 17 00:00:00 2001 From: "Ye.Li" Date: Thu, 9 Jul 2015 17:07:32 +0800 Subject: MLK-11230 imx6: USB: Modify OTG ID pin pad setting to pull up Set the ID pin pad to pull up not the pull down at default, otherwise we can't enter the device mode, but always detect as host. After this change we have to use portA cable to play as host, and use portB cable for device.
