Hi, What would be the most appropriate mailing list to ask about pmbus drivers and power management devices like ltc29**. I'm trying to bring-up some LTC devices using existing drivers and I've encountered some problems while reading e.g. temp1_max_alarm attribute (NACK returned from the target device). I've found what exact line of code introduced in 5.15.x kernel causes this problem but I'm not sure whether or not that line was added according to the pmbus specification expectations therefore the code is fine, but it may that it's the device that responds incorrectly and it's behaviour does not adhere to the pmbus specification.
