This selection enables a simple character driver that supports I2S
|
|
|
|
|
transfers via a read() and write(). The intent of this driver is to
|
|
|
|
|
support I2S testing. It is not an audio driver but does conform to
|
|
|
|
|
some of the buffer management heuristics of an audio driver. It is
|
|
|
|
|
not suitable for use in any real driver application in its current
|
|
|
|
|
form.
