* In some cases the register ranges for pull enable and pull
* direction are the same and thus there are only 3 register ranges.
*
* Since Meson G12A SoC, the ao register ranges for gpio, pull enable
* and pull direction are the same, so there are only 2 register ranges.
*
* For the pull and GPIO configuration every bank uses a contiguous
* set of bits in the register sets described above; the same register
* can be shared by more banks with different offsets.
