This is a pretty painful conversion, with lots of #ifdefs. I think it would be possible to use a common pointer type and reduce this.
But perhaps it does not matter - how long must we be in the state of supporting legacy SPI? Can we convert all TI boards to driver model?
We _really_ need some way to support more than one board per binary before we can move everything to DM only.
I think we can kind of do this today if we stick to using platform data for everything that's board-specific rather than SoC-defined. What we talked about at ELCE was auto-generating the pdata from the device tree, I think.
