Hi James,
There are gpio definition in json files under configuration. How are we using it. Are these gpios being initialized based on configurations here and where are these being used.

There's two answers. 1. The entity-manager can export gipos:
https://github.com/openbmc/entity-manager/blob/master/include/devices.hpp#L43

2. There is a gpio daemon that can configure gpios: 
https://github.com/Intel-BMC/provingground/tree/master/gpiodaemon but 
it's not completely ready yet.

Current usages include dbus-sensors 
https://github.com/openbmc/dbus-sensors/blob/master/src/TachSensor.cpp#L201 
https://github.com/openbmc/dbus-sensors/blob/master/src/ChassisIntrusionSensor.cpp#L175 

and power control I believe. Theres also some ongoing work for fault 
leds https://gerrit.openbmc-project.xyz/c/openbmc/intel-ipmi-oem/+/19709
