The PMIC Audio driver and this API were developed to support the audio playback, recording, and mixing capabilities of the power management ICs that are available from Freescale Semiconductor, Inc.
The following operating modes are supported:
Operating Mode mc13783 ---------------------------- ------- Stereo DAC Playback Yes Stereo DAC Input Mixing Yes Voice CODEC Playback Yes Voice CODEC Input Mixing Yes Voice CODEC Mono Recording Yes Voice CODEC Stereo Recording Yes Microphone Bias Control Yes Output Amplifier Control Yes Output Mixing Control Yes Input Amplifier Control Yes Master/Slave Mode Select Yes Anti Pop Bias Circuit Control Yes
Note that the Voice CODEC may also be referred to as the Telephone CODEC in the PMIC DTS documentation. Also note that, while the power management ICs do provide similar audio capabilities, each PMIC may support additional configuration settings and features. Therefore, it is highly recommended that the appropriate power management IC DTS documents be used in conjunction with this API interface.
