Indeed.

There's no consumer upstreamed yet, I don't know where I shall specify
it. How about keeping the function name and modify the declaration to

+static const struct acpm_handle *acpm_get_by_phandle(struct device_node
*np,
+						     const char *property)

This shall be in line with the syscon API and doesn't force me to
introduce bindings for the consumers now.

Thanks!
