I tried that initially and it caused all the gpio_request calls to fail. The only way I could make gpio_request to work is when I define the pin as gpio mode via mxc_gpio_mode. Regards, Fabio Estevam

I managed to put these definitions in the static pin array as you suggested. In order to do so, I had to fix iomux-v1.c. I will send a v2 version including the iomux-v1 fix. Please let me know if you have any other comments in the other patches so that I can consider them for v2. Thanks, Fabio Estevam
