Again, the Linux pin numberspace is sparse, you can use whatever pin number you like as long as it fits in a u32 and does not overlap with other pins. If you have a problem that the physical pin numbers and the bank offsets or bits you need to poke or something doesn't match, that is an issue for the *driver* not for the pin control subsystem. However the pin control core may provide cross-mapping helpers as discussed elsewhere, but the pin control internal numbering is *not* an issue. Those are just "some number" on a certain pin controller, use the number from the datasheet if you like.
