Haha, I'm in that large majority of people who lack deep knowledge of what's going on, so it definitely confuses me :) I think the stepwise fix would be helpful in making the patches more accessible to us non-experts, and I know it would save me time in reviewing. It may also be useful to people converting other bindings to YAML because it's more obvious what mistakes need to be fixed in the process. Also helpful: changing the subject line to match the existing convention, e.g., dt-bindings: PCI: ftpci100: Convert faraday,ftpci100 to YAML Bjorn
