The letter g comes before i, please move this higher in the list.
Sure i will adrress this in my next patchset.

Can the pins property at least be moved into sc7280.dtsi? Then this can
add bias and drive strength overrides in the board file?
Sure i will adrress this in my next patchset.

Any reason the node shouldn't be called opp-table?
Yes, it can be called but for consistency, we are using the same node names as that on sc7180.
