Does anyone have the new Power Function 2.0 specification or pin out?
Pin 1 - Motor Pin 2 - Motor Pin 3 - GND (0v) Pin 4 - VCC (3.3v) Pin 5 - ID 1 (UART TX for active devices) Pin 6 - ID 2 (UART RX for active devices)
The basic spec for motors is that they are given continuous 3.3V power on pins 3 and 4, voltages to drive the motor on pins 1 and 2, and pins 5 and 6 are used to identify the type of motor that is attached. For the basic motors, I believe that this is simply a known resistance between pins 5 and 6.
LPF2 is also known as Powered Up - ref.
The Bluetooth hub is documented: https://github.com/lego/lego-ble-wireless-protocol-docs . This carries a large

Philo also has useful information.
This doesn't answer the original question but I believe anyone searching for info will benefit from the connection.
