pinconf_generic_parse_dt_config() takes a node as input and generates an array of generic pinconfig values from the properties of this node. As I couldn't find a mechanism to count the number of properties of a node the function uses internally an array to accept one of parameter and copies the real present options to a smaller variable at its end.
