Note that your patch doesn't cleanly apply to Andy's tree.  Context
here shows that you have it between the thermal sensor and the SPMI
bus but the "qcom,sdm845-aoss-cc" node is there in.  It's easy enough
to resolve, but it's usually considered nice to post patches that the
maintainers can apply.

When resolving this myself, I realized that you have the node in the
wrong place anyway.  Nodes with a unit address should be sorted by
unit address.  As you unit address is ae00000 you should be right
above 'dispcc: clock-controller@af00000'.
