That's interesting!

For the Cubox and the AMX33XX boards, the I2C address of the HDMI
registers is 0x70, and the I2C address of the CEC registers is 0x34.

For other boards using the TDA998x family, if the I2C address is
different from 0x70, have you an idea about what can be the CEC I2C
address? (this value is actually hard-coded in the TDA998x driver)
