2016-10-29Documentation: Add documentation for GPIO toggling in ACPI AMLFurquan Shaikh
This document provides information about the different functions that a driver can use for generating ACPI code for toggling GPIO. These functions are expected to be implemented by the SoC. It also defines the different constraints on use of Local variables in ACPI code while implementing these functions.
