I have no experience with omap_hdq platform, but there are quite a few questions
related to IO - you never check whether write was successful or read returned actually
valid data, is it ok? I mean is it correct to assume that read can not return 0xff for example
and it is a sign that something is wrong, or this can not happen?

As for me, I have no objection, but this patch must go via omap tree imo.
