Ohad, Benoit, A gentle reminder - can you please provide your review comments on these patches. I am hoping that this series can make it to 3.13. Paul, The hwmod data patches needs to be merged only after the respective DT node patches are merged, without which the hwmod entry will not have a base address while enabling and idling (using sysc) the hwmod during hwmod initialization. regards Suman > > Changes new in v2: > - Added a new common DT binding documentation and OF helpers (Patch1), > addressing the review comments from v1 [2].
