This is something that still confuses me. What if you have more than one
compatible string? This won't be solvable. See the qcom binding for example,
there are two strings and none matches. In the omap bindings are also two
strings and only one matches. In all cases, including mine, the bindings
check script is fine with that.

So, you basically want it to be called "allwinner,sun6i-a31-hwspinlock.yaml"?

Sorry if I come up with this, but I don't want to just do it, I want to
understand it.
