We faced an i2c transaction time-out issue on Aspeed 2500 EVB board.
It happens when we try to connect on board LM75 at 0x4d driver to bus 7.
We used https://github.com/openbmc/linux/tree/dev-4.6 kernel and also tried https://github.com/shenki/linux/tree/dev-4.7 kernel.
We also tried to change i2c timeout counter (I2CD08) from 3 bits to 5 bits, according to Aspeed AST2400 to AST2500 migration guideline, but it didn't help.
Is that a known issue?
Is there a known solution you can point us to?
Thanks for the assistance,
