i wan to access all gpios from user space using application.
do i need to write a module driver to create a gpio node that application can use it to read/write on gpio pin.
gpiochip_setup_dev: registered GPIOs 320 to 511 on device: gpiochip0 (tegra-gpio)
[ 0.452408] gpiochip_setup_dev: registered GPIOs 256 to 319 on device: gpiochip1 (tegra-gpio-aon)
