From 8991fdef6d94b3c32722f413f399c3fce0b5061d Mon Sep 17 00:00:00 2001 From: "Ye.Li" Date: Thu, 31 Dec 2015 15:24:45 +0800 Subject: [PATCH] usb:ci_udc: Remove ULPI setting for i.MX OTG controller All the i.MX6, i.MX23 and i.MX28 OTG controllers only support UTMI interface. Set to ULPI is not correct, even the controller will reject this setting in PORTSC register.
