How do I use the gpio from the ALEOS framework? Also where can I find the complete list of devicetree names and descriptions for the RV50?

To answer my own question to help anyone else out that is having an issue hunting down documentation. GPIO is manipulated through the devicetree lua module. The commands for the GX400 work on the RV50. Search for ALEOS AF Device Parameter Access Technical Article to find the complete list of devicetree system variables.
