You shouldn't have compatible strings for subfunctions of a MFD unless these represent meaningful reusable IPs that can exist separately from the parent chip, that's clearly not the case here. All you're doing here is encoding Linux internal abstractions which aren't OS neutral and might change in future (for example clocking might move more into the clock API).
While that's nice, the of_node doesn't get populated if there isn't a compatible string. And people don't like workarounds for the missing of_node.
What workarounds are you referring to? Why would this need any kind of workaround, there is no requirement for magic broken nodes like this in the subsystem and if there is we should fix that rather than bodge the ABI.
