Snapdragon 660 GPIO PINS

I want to get the gpio pins on the mobile phone and the information of the gyro sensor, how can I do it?

I don't think you can reach sensors using gpio on sdm660 platfrom, they might be "hidden" behind Snapdragn Sensor Core (but I'm not sure)

If you need to access any ubused GPIOs from linux userspace, you can use libgpiod CLI tools or C API for that (or one of its bindings )

I want to use it with Android operating system installed, like linux operating system, but do I need to be rooted operating system, I want to use Ros/ros2 operating system.

If I understand correctly, ros is based on ubuntu, there are some packages

$ apt search libgpiod
gpiod/jammy 1.6.3-1build1 amd64
  Tools for interacting with Linux GPIO character device - binary

libgpiod-dev/jammy 1.6.3-1build1 amd64
  C library for interacting with Linux GPIO device - static libraries and headers

libgpiod-doc/jammy,jammy 1.6.3-1build1 all
  C library for interacting with Linux GPIO device - library documentation

libgpiod2/jammy 1.6.3-1build1 amd64
  C library for interacting with Linux GPIO device - shared libraries

debian man page for command-line tool gpioset - https://manpages.debian.org/experimental/gpiod/gpioset.1.en.html
kernel must be built with CONFIG_GPIO_CDEV

a very useful website, I will do some research on this, thank you very much for sharing the resource.
