| 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. |
