If anyone has any objections, please let me know. ------------------ From: William Breathitt Gray [ Upstream commit 2ba5772e530f73eb847fb96ce6c4017894869552 ] The direction of the IDIO-16 GPIO lines is fixed with the first 16 lines as output and the remaining 16 lines as input. Set the gpio_config fixed_direction_output member to represent the fixed direction of the GPIO lines.
