There are drivers and driver libraries. Drivers provide interfaces to
the userspace.. and libraries are not designed to expose anything to the
external world, and are meant to be used by other drivers to perform
some operation... to my knowledge, McBSP falls in that world of "driver
libraries" just like DMA. if you would like to do something with it, you
should be in kernel space.. Now, if your usecase insists on having a
userspace access... you could write your own wrapper to the driver
library just like what i2c-dev does for I2C driver library.
