Hi
The right way to do it is to use the existing API by exposing the
inverter (there are existing examples in the tree, using the
hierarchical model)...

A much simpler version can be written in a few minutes, see below...
Can something like that be used if the parent domain is not hierarchical (i.e. does not provide alloc(),
but provides map() instead)?
In particular, gpio-rcar currently provides irq domain that is not hierarchical.
As well as quite a few other gpiochips.
