Background
The Kernel is a critical component of the Linux operating system that provides core functionality and acts as an interface between hardware and software. It manages system resources, facilitates communication between different software components, and ensures the overall stability and security of the system. ASoC (Audio System on Chip) is a subsystem within the Kernel that handles audio-related functionalities. The mediatek module in ASoC is responsible for supporting MediaTek audio hardware. One specific module, mt2701_wm8960_machine_probe, is used for the MediaTek MT2701 platform with a WM8960 audio codec.
