They are just for debugging after all. So, I remove the yaml file and add the bindings to the documenation, then? Makes sense to me because it is for debugging and not really official. > I would consider housing this tool under drivers/gpio actually. > We have other funky things like gpio-sim and gpio-aggregator > so why not. Heh, my first draft was placed in drivers/gpio. I'd be happy to have it there. > I would create a Kconfig menu with "GPIO hardware hacking tools". >=20 > But Bartosz would need to agree on that idea.
