-Subject: [PATCH 04/11] MIPS: BCM63XX: add OHCI/EHCI configuration bits to
- common USB code
-
-This patch updates the common USB code touching the USB private
-registers with the specific bits to properly enable OHCI and EHCI
-controllers on BCM63xx SoCs. As a result we now need to protect access
-to Read Modify Write sequences using a spinlock because we cannot
-guarantee that any of the exposed helper will not be called
-concurrently.
