What is the expected difference between a dependency on DW_DMAC_CORE and one on DW_DMAC_CORE != n?
No functional difference, it's more to make the menuconfig options more obvious. Without this patch, menuconfig will not show the legacy byt-max98090 and byt-rt5640 options if the DW_DMAC_CORE is built as a module. While we want to encourage folks to use the newer DPCM drivers, we also want to leave these options accessible.
My point is that you've written the above in a very confusing manner - I have to think about what it means while just a dependency would be clear and obvious.
