Stephen Warren bacdbe0773 regmap: introduce fast_io busses, and use a spinlock for them ... Some bus types have very fast IO. For these, acquiring a mutex for every IO operation is a significant overhead. Allow busses to indicate their IO is fast, and enhance regmap to use a spinlock for those busses.
