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