IMHO, the older binding needs to be supported as well. It's fine to update the DTS for the new binding, but even Documentation says touchscreen-max-[xy] and if the driver changed that, the driver should be fixed too. Besides, it seems like this has been in tree since v3.16:
$ git describe a38cfebb56898633687ab337fd53710e63a0aedd v3.15-rc5-72-ga38cfebb5689
So, because this has been wrongly documented for so long, we should support both bindings. Sure, deprecate touchscreen-max-[xy], but they must still be supported, IMO.
In any case, for this patch:
