+Description:
+		The character device files /dev/gpiochip* are the interface
+		between GPIO chips and userspace.
+
+		The ioctl(2)-based ABI is defined in
+		[include/uapi]<linux/gpio.h> and documented in
+		Documentation/userspace-api/gpio/chardev.rst.
+
+		The following file operations are supported:
+
+		open(2)
+		  Currently the only useful flags are O_RDWR.
+
+		ioctl(2)
+		  Initiate various actions.
+
+		  See Documentation/userspace-api/gpio/chardev.rst
+		  for a description of all ioctls.
+
+		close(2)
+		  Stops and free up the I/O contexts that was associated
+		  with the file descriptor.
