-'''
-TrekStor EBR30-a I2C demux protocol decoder.
-
-Takes an I2C stream as input and outputs 3 different I2C streams, for the
-3 different I2C devices on the TrekStor EBR30-a eBook reader (which are all
-physically connected to the same SCL/SDA lines).
-
-I2C slave addresses:
-
- - AXP199 battery management chip: 0x69/0x68 (8bit R/W), 0x34 (7bit)
- - H8563S RTC chip: 0xa3/0xa2 (8bit R/W), 0x51 (7bit)
- - Unknown accelerometer chip: 0x2b/0x2a (8bit R/W), 0x15 (7bit)
