Hi Jacek, For patches 1-4 and 6 (assuming you fix the small issue in patch 3) you can add Reviewed-by: Oded Gabbay <ogab...@kernel.org> For patch 5 I had a comment/question, please reply to it. Once we sort that thing that patch is also r-b by me. Patch 7 - I prefer someone else who knows about PM to look at it. In habana we don't support power management (in the driver) so I have never dealt with that and therefore I have no idea if you use the kapi correctly.
