Where does ADMAIF driver reside in kernel, who configures it for normal
dma txns..?

Not yet, we are in the process of upstreaming ADMAIF driver.
To describe briefly, audio subsystem is using ALSA SoC(ASoC) layer. 
ADMAIF is
registered as platform driver and exports DMA functionality. It 
registers PCM
devices for each Rx/Tx ADMAIF channel. During PCM playback/capture 
operations,
ALSA callbacks configure DMA channel using API dmaengine_slave_config().
RFC patch proposed, is to help populate FIFO_SIZE value as well 
during above
call, since ADMA requires it.

Also it wold have helped the long discussion if that part was made 
clear
rather than talking about peripheral all this time :(

Thought it was clear, though should have avoided using 'peripheral' 
in the
discussions. Sorry for the confusion.
