Thus far, Linux has two separate drivers for each and they are diverging considerably. This series unifies them into a single driver with small SPI and parallel bus specific parts. The approach here is to first separate out the SPI specific parts into a separate file, then add parallel bus accessors in another separate file and then finally remove the old parallel bus driver. The reason for replacing the old parallel bus driver is because the SPI bus driver is much higher quality.
