View GPIO information and register description

We develop based on Jetson NANO.
Among the information printed by the Cat /sys/kernel/debug/gpio command, how to check the missing gpio information (such as GPIO6)? ,

Enter the information printed by Cat /sys/kernel/debug/tegra_gpio, please provide an explanation of the meaning of the register?

I’m moving this topic to Jetson Nano series.

may I know which platform you’re actually works on? is it Jetson Nano or Xavier NX?
because I see you’re having AON-GPIO in the gpiochip1, which is not for Nano series.
