I have addressed this in v2: https://lore.kernel.org/linux-devicetree/20220917041136.526446-1-sergio.paracuellos@gmail.com/T/#u > > I didn't check the rest for existing documentation... The rest of compatible strings for cpu's that I am listing here seems to not contain associated txt bindings description, so I guess if anything extra is needed / required can be added afterwards?
