audio: Multizone: Dynamic JAMR3 support
JAMR3 board may not always be present in the system, the port
usage is being changed dynamically to:
- JAMR3 is present
o Cabin : port 1, slots 0 & 1
o Mic : port 1, slot 2
o Back Mic: port 1, slot 3
- JAMR3 is not present
o Cabin : port 0, slots 0 & 1
o Mic : port 0, slots 0 & 1
Above port allocation allows:
- Relinquish McASP3 (port 0) when JAMR3 is connected. This allows
DSP Radio to own that McASP instance for its rendering.
- Hardware setups that don't have JAMR3 fall back to the port 0
that is present in the main Jacinto6 EVM board (CPU board).
The default hardware setup is assumed to have JAMR3 connected.
When it's not connected, the property "persist.audio.use_jamr"
must be set to "0" or "false" and system has to be rebooted
(or media server restarted). This is meant to be a development
option.
