This is a proposal for adding ACPI support for pin controller configuration. It has been developed to enable the MinnowBoard and IoT community by providing an easy way to specify pin multiplexing and pin configuration. This proposal is based on using _DSD properties to specify device states and configuration nodes and it follows closely the device tree model. Device states are defined using the Device Properties format and the configuration nodes are defined using the Hierarchical Properties Extension format. The generic properties for the configuration nodes are the same as the ones for device tree, while pincontroller drivers can also define custom ones.
