| 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. |
