This subsystem has no drivers with the similar feature, thus it's new
design for data transmission. The design supports below things:
1. Hardware features:
1.1. Data transmission is done by direct media access (DMA).
1.2. Hardware cares of two points for its data transmission; one is
hwptr and another is appl_ptr on PCM buffer dedicated for the
data transmission.
1.3. (perhaps)The granurarity of data transmission can be differed,
not fixed to the size of 'period'.
I realized that 'granularity' (misspelled...) is not proper in this
context. Here, I described intervals to start data transmissions by DMA.
The transmission can be managed by pre-programmed descriptors on device
register, or service routines for interrupts on drivers, and so on.
