Hi Heiko, I found that Documentation/devicetree/bindings/arm/rockchip.yaml uses pattern of one board per item in oneOf. This leads to quite big file, with many entries, although gives nice description for each board. I find enum-based pattern, like FSL [1], much more readable and compact. What do you think? I could re-organize the arm/rockchip.yaml, but I don't want to mess with your preference.
