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.
