Help text

This option causes char devices created for FSI devices to be located under a common /dev/fsi/ directory. Set to N unless your userspace has been updated to handle the new location.

Additionally, it also causes the char device names to be offset by one so that chip 0 will have /dev/scom1 and chip1 /dev/scom2 to match old userspace expectations.

New userspace will use udev rules to generate predictable access symlinks in /dev/fsi/by-path when this option is enabled.
