    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://urldefense.proofpoint.com/v2/url?u=https-3A__gerrit.openbmc-2Dproject.xyz_c_openbmc_intel-2Dipmi-2Doem_-2B_19709&d=DwICaQ&c=5VD0RTtNlTh3ycd41b3MUw&r=v9MU0Ki9pWnTXCWwjHPVgpnCR80vXkkcrIaqU7USl5g&m=Nj0NvY_nyfomDAeLgrpDr2-LxqTeWVYFrdf-zDaZfTA&s=a8h5uJrO1qKh8QcrzO01zqj6q7OrAPri9ah5_zQRynA&e=
