Pekon,
A few questions regarding this patch, despite the fact I'm not sure it will
ever be included.

Is this output pin?

Again: is this output pin?

The devicetree binding says these wait properties are bool, so the above
should be:
gpmc,wait-on-read;
gpmc,wait-on-write;
But the problem is that there's no wait-pin defined, so this not enabled.
Could you explain what should be the correct binding? This is very confusing
for me.
Thanks!
