This is a rewrite of the Kinetis GPIO driver which follows the refactored API in [1]. Pins are specified using the GPIO_PIN(PORT_x, y) macro, e.g. GPIO_PIN(PORT_E, 25) for the PTE25 pin. The interrupt pin handling is now implemented as a linked list, this is more memory efficient, but with a minor variation in interrupt latency depending on in what order the pins were initialized at runtime. Because the linked list entries are taken from a shared pool, there is also the possibility of running out of available configuration slots, define the preprocessor macro GPIO_INT_POOL_SIZE in periph_conf.h if you need more than 16 pins configured for interrupts in the same application.
