Detailed Description

Unified DMIC data-path configuration.

Use this structure with dmic_config_data_path to configure data path from a single API. Buffer layout policy:

• Single-channel capture uses per-channel layout.
• Multi-channel capture uses interleaved layout. Example: ch0_s0, ch1_s0, ch0_s1, ch1_s1, ... The driver automatically selects interleaved mode when more than one channel is active.
