This machine driver provides support for different configurations: RT700, RT711, RT1308 (1x and 2x, I2S or SoundWire mode), and RT715 CometLake, Icelake, TigerLake. PDM digital microphones HDMI To avoid introducing one driver per configuration, this common machine driver relies on platform-specific information, tables and quirks to dynamically create the relevant dailinks. Unlike a lot of machine drivers, we use different DAI links for SoundWire capture and playback since the Cadence PDIs can do capture OR playback, not both simultaneously. For each configuration, the card component string is updated so that UCM can select the relevant parts.
