   4 Subject: [PATCH 23/93] drivers: usb: fsl: add USB ULPI init code
   5
   6 This adds the required code to set up a ULPI USB port, for
   7 new NXP USB PHY used in QorIQ platforms.
   8
   9 To use this both CONFIG_USB_ULPI and CONFIG_USB_ULPI_VIEWPORT
  10 have to be set in the board configuration file.
