I would say this looks very good.

One remaining discussion would be the mutex functionality that should be placed in pretty much anything under drivers/api. You have those acquire/release API's which map well onto a mutex locking mechanism so I'd say we should add it at this stage. Might be tricky to test though...

• Added mutex_* calls in the no_os_dma API.
• Fixed a merge conflict.
