A quick look at the code suggests this issue affects GPIO banks D and E in the AST2400 and AST2500, and banks T and U in the AST2600. Functionally I think the patch is fine.

Some gpio pin at aspeed soc is input only and the prefix name of these pin is "GPI" only. This patch fine-tune the condition of GPIO check from "GPIO" to "GPI".
