Developing an SAI Driver for the STM32H7 Series

[mustafaabdullahk]

Hello Zephyr Community,

I'm planning to develop a driver to support the SAI module in the STM32H7 series. This module provides flexibility for digital audio applications by supporting protocols such as I2S, PCM, TDM, and SPDIF. The SAI hardware includes two independent blocks (A and B) and offers full-duplex, master/slave modes, FIFO, and DMA support.

Features:

• Supported Protocols: I2S, PCM, TDM, SPDIF, AC'97.
• Modes and Configurations: Master/slave, full/half-duplex, and internal/external synchronization.
• Clock Management and Synchronization: Internal sync supports multiple data lanes in full-duplex applications.

I'd appreciate your feedback and advice, especially regarding integration with Zephyr’s audio API and driver design.

Thank you!
