Cover letter [PATCH 0/4] OMAP-GPMC generic timing migration
Hi Daniel,

I doubt whether auxdata would help here, it seems using compatible field alone would help in deciding relevant custom timing routine. Whether we want this kind of peripheral knowledge in gpmc driver instead of using generic timing routine has to be decided though.

Another thing that might be worth thinking about is that apart from the GPMC host controller and the peripherals, there could be other components like level shifters or series resistors on the board that limit the maximum speed of transactions. So in fact we might be better off storing all that timing details in the DT, as they are in fact highly application specific.
Yes, making it future proof for these kind of scenarios was one of the reason's that initially triggered generic timing path.
