I have posted two further revisions of this series, the latest is v6 [1]. I added additional patches in v5 that added the concept of reserved locks, and I have posted them as a separate RFC [2] for v6 so as to not block the core DT support. In anycase, the latest v6 version does not define the of_hwspin_lock_request_specific() function anymore, and it is replaced with of_hwspin_lock_get_id() function, based on Ohad's review comments on v5, and I did add the support for -EPROBE_DEFER in this API, without changing any of the existing return code conventions. I am yet to receive any comments on v6, but that series should address both your need for a probe deferral and Ohad's request to not change any return types. Please give it a try and let me know if you have any comments. regards Suman [1] http://marc.info/?l=linux-arm-kernel&m=141055365513902&w=2 [2] http://marc.info/?l=linux-arm-kernel&m=141055554214657&w=2 > > @Ohad, do you object merging Suman's patch in it's current form?
