Subject[PATCH 2/9] dt-bindings: msm/dpu: Add simple-bus to dpu bindings
Date
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.
