   4 Subject: [PATCH 03/11] MIPS: BCM63XX: move code touching the USB private
   5  register
   6
   7 This patch moves the code touching the USB private register in the
   8 bcm63xx USB gadget driver to arch/mips/bcm63xx/usb-common.c in
   9 preparation for adding support for OHCI and EHCI host controllers which
  10 will also touch the USB private register.
