Lochnagar is an evaluation and development board for Cirrus Logic Smart CODEC and Amp devices. It allows the connection of most Cirrus Logic devices on mini-cards, as well as allowing connection of various application processor systems to provide a full evaluation platform. This driver adds support for the hardware monitoring features of the Lochnagar 2 to the hwmon API. Monitoring is provided for the board voltages, currents and temperature supported by the board controller chip.

Add support for fan capability registers in order to distinct between the systems which have minor fan configuration differences. This reduces the amount of code used to describe such systems. The capability registers provides system specific information about the number of physically connected tachometers and system specific fan speed scale parameter. For example one system can be equipped with twelve fan tachometers, while the other with for example, eight or six. Or one system should use default fan speed divider value, while the other has a scale parameter defined in hardware, which should be used for divider setting. Reading this information from the capability registers allows to use the same fan structure for the systems with the such differences.
