I have two questions about the GPIOs of the efusA9.
1) Can I use the GPIOs for LCD_Bx (GPIO5_IO06 - GPIO05_IO11) as soon as I disable the displays in the efusa9dl.dts file? Or is there something other I have to change?
2) Are the GPIOs usable in C wihtout using the /proc files? We don't need to toggle them really fast but I don't know how much overhead the proc files will add.
