[greybus-dev] binding gb gpio device to gb-phy driver?

Hi List!

I'm currently using gbridge / tcpip with the IID1-simple-gpio-module.mnfs example to hook up a fake module that just responds to socket I/O.

A couple of small changes were required, but everything seems to be parsed, bundles, cports are all created.

However, for some reason, greybus does not seem to automatically bind the device to the gb-gpio driver, nor does it probe the device. I only see pings after the svc has inserted my fake module and handshake is complete.

Is anyone aware if a separate step that is required to bind the device to the driver? I've tried

sudo sh -c 'echo -n 1-2.2.1 > /sys/bus/gbphy/drivers/gpio/bind'

but that gives me -ENODEV

Any pointers would be great!

Thanks,

C
