This should be determined by the "compatible" property alone, I think.
we specifically put this into dts as almost each of the SoC versions has a different register layout. i really want to avoid having to patch the gpio driver whenever ralink/mtk decides to "change the registers yet again".
Yes, that's what we have to do in e.g. driver/net/ethernet/sh_eth.c. There are 5 register layouts known by now, 2 of them were added recently. :-)
I can change it if must be.
Yes, I think it must be this way.
but i really would prefer to keep it this way as it will safe me lots of time in future
