* Name: i2schar_register
*
* Description:
* Create and register the i2s character driver.
* Create and register the I2S character driver.
*
* The I2S character driver is 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.
*
* Input Parameters:
* i2s - An instance of the lower half I2S driver
