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 <michal.chvatal@nxp.com>
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 <michal.chvatal@nxp.com>
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 <michal.chvatal@nxp.com>
Add test for the `get_caps()` API in both I2S and DMIC driver test suites. Tests validate successful operation, capability value ranges, and error handling with NULL parameters. Tests handle drivers that don't implement get_caps by gracefully skipping when -ENOSYS is returned, ensuring compatibility across different driver implementations.

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.
