AGX carrier board version

Hi Team,

Please help me in understanding the carrier board version.

tegra194-p2822-0000-a00.dtsi
I understand that “a00” is the carrier board version.
what does “0000” specifies here?

tegra194-power-tree-p2888-0001-p2822-1000.dtsi
In the above dtsi, carrier board name has 1000 extension(p2822-1000). what does it mean?

Thanks,

p2888 is the Xavier module and p2822 is the devkit carrier board.

The rest of things are NVIDIA internal use only.
