Introduce `get_caps()` API to DMIC, I2S, and Codec subsystems to expose driver-specific audio capabilities such as supported sample rates, bit widths, channel counts, buffer requirements, and frame timing. Introduce common audio definitions in `audio_caps.h` to unify capability flags across subsystems. Signed-off-by: Michal Chvatal <[email protected]>
Implement the `get_caps()` API for MCUX I2S Flexcomm, DMIC, and WM8904 audio drivers to expose driver-specific capabilities including supported sample rates, bit widths, channel counts, and buffer requirements. All drivers set temporary 10ms minimum frame interval as workaround for MediaPipe library compatibility. Signed-off-by: Michal Chvatal <[email protected]>
Changes affect: - drivers: i2s_mcux_flexcomm, dmic_mcux and wm8904 - audio subsystem headers: i2s.h, codec.h, dmic.h No functional changes, formatting improvements only. Signed-off-by: Michal Chvatal <[email protected]>

This PR introduces
get_caps()API to DMIC, I2S, and Codec subsystems, enablingdrivers to report their audio capabilities such as supported sample rates, bit widths,
channel counts, buffer requirements, and frame timing.
It implements the API for MCUX I2S Flexcomm, DMIC, and WM8904 audio drivers.
It also introduces common audio definitions in
audio_caps.hto unify capabilityflags across subsystems.
Changes are related to new MediaPipe library.
