Detailed Description

I2S memory interface operations.

This structure defines the backend memory interface operations used by the I2S driver to transfer audio data between memory and the I2S FIFO.

The implementation can vary depending on the selected memory interface, such as DMA or any future memory interface mechanism.

The I2S core driver interacts with the memory interface only through this abstraction layer, enabling backend pluggability without modifying the core I2S logic.
