I don't think there's any requirement that the Linux driver source
filename needs to match the DT binding compatible value in any way.
Given the bindings are OS-agnostic, naming the binding file based on the
compatible value seems better than naming the binding based on the Linux
driver name when there's a discrepancy. I see you've renamed the file in
V3, so everything's fine.
