Thanks for your reply to me, I had missed that you continued this work.

I find it somewhat awkward to have to call both of_hwspin_lock_get_id() and
then hwspin_lock_request_specific(), but I found the request from Ohad, so
let's stick with it.

Am I right that hwlock-num-locks and hwlock-base-id are optional from the
frameworks perspective and only there to aid the hwspin drivers? If so it is
strange to have in the common binding and have the helper functions in the core
for simply reading hwspin device specific properties.

Otherwise I think it looks sane, although I haven't spend that much time
reviewing it.

I did throw it into my tree and gave it a testrun with the Qualcomm code I've
been working on. So for the non-omap parts:
