20 The BMC chip is integrated in some Intel Progr
21 Cards (PAC). It connects to a set of sensor ch
22 sensor data of different components on the boa
23 responsible for sensor data sampling and recor
24 registers. The host driver reads the sensor da
25 registers and exposes them to users as hwmon i

27 The BMC chip is implemented using the Intel MA
28 reprogramed to some variants in order to suppo
29 PACs. The driver is designed to be able to dis
30 variants, but now it only supports the BMC for
