^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 15) Description
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 16) -----------
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 17)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) This driver adds the temperature, voltage, current and power reading
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) support for the Intel MAX 10 Board Management Controller (BMC) chip.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) The BMC chip is integrated in some Intel Programmable Acceleration
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 21) Cards (PAC). It connects to a set of sensor chips to monitor the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 22) sensor data of different components on the board. The BMC firmware is
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 23) responsible for sensor data sampling and recording in shared
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 24) registers. The host driver reads the sensor data from these shared
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 25) registers and exposes them to users as hwmon interfaces.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 26)
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) The BMC chip is implemented using the Intel MAX 10 CPLD. It could be
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) reprogramed to some variants in order to support different Intel
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) PACs. The driver is designed to be able to distinguish between the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) variants, but now it only supports the BMC for Intel PAC N3000.
