Equilibrium driver is a pinctrl and GPIO driver for Intel Lightning
Mountain network processor SoC that supports both the GPIO and pin
control frameworks. It provides interfaces to setup pin muxing, assign
desired pin functions, configure GPIO attributes for LGM SoC pins.
Pin muxing and pin config settings are retrieved from device tree.
