I thought Rob said that he did NOT want to use version numbers in
compatible strings.  And what's the difference between these three
versions anyway?


This was already discussed here.

https://lkml.org/lkml/2015/11/2/689

The agreement was to use

compatible = "qcom,hidma-mgmt-1.1", "qcom,hidma-mgmt-1.0", "qcom,hidma-mgmt";

I'll be adding code for v1.1 specifically in the future.
