We have a whole bunch of child devices that we really just want treated as other devices to instantiate. Add the "simple-bus" property for this. Commit-notes This bindings file really needs to move over to yaml. Hopefully someone at Qualcomm who's working on display code can help with that. Right now on Linux we have a manual call to of_platform_populate() to populate our children. That's pretty non-ideal as described in another patch in this series and I'm trying to remove it. I'm not sure how much of a hack to consider "simple-bus". I've seen it used like this before, but if folks tell me that it's terrible then I guess we'll have to figure some other way out of our crazy -EPROBE_DEFER loop in Linux.
