Question for the Rockchip U-boot maintainers:

Would you like to keep this method for backward compatibillity together with "gpio-ranges"?
All dtsi files must be changed first!

If you have the time...
As you are already touching gpio with a common fall back string then it's best you do that in separate patch series.
Mind it involves a lot of dtsi changes before this can be merged.
Moving gpio nodes to root must also make it work both full U-boot and SPL reduced DT and with platdata if possible.
