Either the binding document or this code is wrong. The biding is in patch titled: "mfd: tc3589x: Add device tree bindings" and yes, you are right, this seems wrong. (The example in that patch is wrong too.) > I'm confused as to how this can work. Are you using /bits/ 8 in your dts? Yes indeed I do. So it was working fine... I'll adjust this to use u32:s, even if it seems odd supporting keypads with 255+ columns and rows... well it's in there.
