From 271adb5c0546b080fb350a41520c600a16739f1a Mon Sep 17 00:00:00 2001
From: Rajesh Bhagat <rajesh.bhagat@nxp.com>
Date: Fri, 6 May 2016 09:05:29 +0530
Subject: [PATCH 23/93] drivers: usb: fsl: add USB ULPI init code
This adds the required code to set up a ULPI USB port, for
new NXP USB PHY used in QorIQ platforms.
To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT
have to be set in the board configuration file.
