New register has been introduced with PTL in the vendor specific SHIM registers, outside of the IPs itself for microphone privacy status handling. Via the PVCCS register the current microphone privacy status can be checked and the interrupt generation on status change can be enabled/disabled. The status change interrupt is routed to the owner of the interface (DSP/host). The PVCCS is provided for each sublink under the IP to make it possible to control the interrupt generation per sublink. On status change the MDSTSCHG bit needs to be cleared for all sublink of the interface to be able to detect future changes in privacy. The status bit (MDSTS) is volatile in all PVCCS register, it reflects the current state of the GPIO signal. Microphone privacy is a hardware feature (if enabled and configured that way), the host has only passive, monitoring role. The added functions are generic to be future proof if the mic privacy support is extended beyond Soundwire and DMIC links.
