The Aspeed pinconf data structures are split into 'conf' and 'map' types, where the 'conf' struct defines which register and bitfield to manipulate, while the 'map' struct defines what value to write to the register and bitfield. Both structs have a mask member, and the wrong mask was being used to tell the regmap which bits to update. A todo is to look at whether we can remove the mask from the 'map' struct.
