Cannot control GPIO in my driver in the L4T35.3.1

[Xzz]

Upon reviewing the log, I realized that I was requesting GPIO before gpiochip initialization (the kernel stage starts loading it after 6 seconds),

[    1.209913] xz failed to request rs232 enable GPIO err: -517
[    6.641029] gpiochip0: registered GPIOs 348 to 511 on tegra234-gpio
[    6.648323] gpiochip1: registered GPIOs 316 to 347 on tegra234-gpio-aon

so I delayed the loading of my driver. Now I am encountering new log errors

[    6.530373] gpiochip0: registered GPIOs 348 to 511 on tegra234-gpio
[    6.537730] gpiochip1: registered GPIOs 316 to 347 on tegra234-gpio-aon
[    7.924990] tegra186-gpio 2200000.gpio: invalid port number: 48
[    7.931078] xz failed to request rs232 enable GPIO err: -517

Then I discovered that someone else has encountered the same issues and errors as me.

@frander.diaz

And that configuration fails to find the reset-gpios.

[   91.427682] tegra186-gpio 2200000.gpio: invalid port number: 60
[   91.433774] device 10-0061: reset-gpios not found
[   91.438705] device 10-0061: tegra camera driver registration failed

Please help me to check why my port number is wrong.
