hwmon: lochnagar: Add Lochnagar 2 hardware monitoring driver 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.

Kernel Driver Lochnagar
docs: hwmon: convert three docs to ReST format Those three new drivers were missed on the initial conversion to ReST format. So: - Rename them to .rst; - Add them to the hwmon index.rst index; - add some blank lines at the "Supported systems:" part, in order to allow Sphinx to properly identify new lines, suppressing warnings and avoid it to output some random lines in bold; - When multiple authors are involved, change the authors part to a list, in order to avoid adding blank lines. - adjust the table cells (one of the tables seemed to be assuming that tab is 4 positions instead of 8) and add the table markup. - be sure that the section markups have the same number of characters as the section title.

Supported systems:
* Cirrus Logic : Lochnagar 2
Author: Lucas A. Tanure Alves
Description
-----------
Lochnagar 2 features built-in Current Monitor circuitry that allows for the
measurement of both voltage and current on up to eight of the supply voltage
rails provided to the minicards. The Current Monitor does not require any
hardware modifications or external circuitry to operate.
The current and voltage measurements are obtained through the standard register
map interface to the Lochnagar board controller, and can therefore be monitored
by software.
