"""
This script parses the target DTS file name and determines which DTS input
file to use as the source, then the DTS source file name to stdout. For
example, if the target is:
build/usrp_x410_fpga_XG_100.dts
then it will print the input DTS file name (replacing the directory and
removing the _100):
dts/usrp_x410_fpga_XG.dts
Note: This code assumes it's being run from the top x400 directory, because it
will always add dts/ input file path.
usage: get_dts_input.py [-h] --target INPUT
Arguments:
-h, --help Show this help message and exit
--target TARGET The target file name (e.g., build/usrp_x410_fpga_X4_200.dts)
