gpio_ext_common module

Common functions for external GPIO

This module wraps calls to the gpio_x functions (GCC only!) and redirects calls with port GPIOEXTx to modules.

See gpio_ext_pca95xx as an example implementation.

Example for airframe file

Add to your firmware section:

<module name="gpio_ext_common"/>
