In the RFC I sent out the proposed flags were:
#define VFIO_DEVICE_FLAGS_PLATFORM (1 << ?) /* A platform bus device */
#define VFIO_DEVICE_FLAGS_DEVTREE (1 << ?) /* device tree info available */
Since you are only implementing the first part, the platform
device support, just call it: VFIO_DEVICE_FLAGS_PLATFORM
I think the 'platform' term is more accurate as we are providing
a mechanism to expose devices on the /sys/bus/platform bus to
user space.
