Where else in the tree does it make sense to locate the 'syscon-reboot-mode' node? Locate nodes where they logically belong. > According to the driver 'syscon-reboot' > can't lack the regmap property because it's mandatory, while here you refuse > to have even optional support.

There's plenty of bad or "don't follow current best practice" examples in the tree for all sorts of things. That is not a reason for doing something in a new binding or adding to an existing one. Rob
