189efdf074 Use NO_PIN, not 0, for PDMIn unset pins. 
Also:
- Use NO_PIN, not 0xff for I2SOut (cosmetic fix only; no actual functional change)
- Add VOLTAGE_MONITOR/BATTERY, ACCELEROMETER_INTERRUPT pins for LED Glasses Driver

912fd7759d nrf: PDMIn: Implement 
So far, this supports only 16kHz and 16-bit samples with a fixed gain.
This is enough to support the basic functionality of e.g., sensing
ambient audio levels.
