     15Description
     16-----------
     17
     18This driver adds the temperature, voltage, current and power reading
     19support for the Intel MAX 10 Board Management Controller (BMC) chip.
     20The BMC chip is integrated in some Intel Programmable Acceleration
     21Cards (PAC). It connects to a set of sensor chips to monitor the
     22sensor data of different components on the board. The BMC firmware is
     23responsible for sensor data sampling and recording in shared
     24registers. The host driver reads the sensor data from these shared
     25registers and exposes them to users as hwmon interfaces.
     26
     27The BMC chip is implemented using the Intel MAX 10 CPLD. It could be
     28reprogramed to some variants in order to support different Intel
     29PACs. The driver is designed to be able to distinguish between the
     30variants, but now it only supports the BMC for Intel PAC N3000.
