This patch adds support to Q6AFE (Audio Front End) module on Q6DSP.

AFE module sits right at the other end of cpu where the codec/audio devices are connected.

AFE provides abstraced interfaces to both hardware and virtual devices. Each AFE tx/rx port can be configured to connect to one of the hardware devices like codec, hdmi, slimbus, i2s and so on. AFE services include starting, stopping, and if needed, any configurations of the ports.

This patch adds support to Q6ADM (Audio Device Manager) module in q6dsp. ADM performs routing between audio streams and AFE ports. It does Rate matching for streams going to devices driven by different clocks, it handles volume ramping, Mixing with channel and bit-width. ADM creates and destroys dynamic COPP services for device-related audio processing as needed.

This patch adds basic support to ADM.

This patch adds basic support to Q6 ASM (Audio Stream Manager) module on Q6DSP. ASM supports up to 8 concurrent streams. each stream can be setup as playback/capture. ASM provides top control functions like Pause/flush/resume for playback and record. ASM can Create/destroy encoder, decoder and also provides POPP dynamic services.

This patch adds support to basic features to allow hdmi playback.
