Why changing this? You just added these bindings not so long time ago... This is very confusing to push bindings and then immediately ask to remove them. Best regards, Krzysztof

One more point - anyway this should be revert with clear explanation WHY you are reverting bindings. Same for second patch. Best regards, Krzysztof

See this revision as a proposal of something that has been asked multiple times in previous reviews. See message from Stephen Boyd on last revision [0], or discussion with Rob Herring on much earlier revision [1]. Proposal from Stephen Boyd of using auxiliary devices makes sense, that could be the future direction of this series. It won't change the dt-bindings aspect of it, only the driver implementations.

I'll make sure to use standard revert formatting and explain why it is being done. Thanks, -- Théo Lebrun, Bootlin Embedded Linux and Kernel engineering https://bootlin.com

Why v7 was sent ignoring Rob's comments: https://lore.kernel.org/all/20240221-mbly-clk-v7-3-31d4ce3630c3@bootlin.com/ Best regards, Krzysztof

Yes. The gist of it is that I had misunderstood the messages. Mostly, I did not understand how to implement separate Linux driver with the desired devicetree structure (no subnode on the syscon for each feature). I was missing knowledge about Linux infrastructure allowing for that. MFD and auxdevs are two approaches, with auxdevs being preferred. The latest revision finally takes those comments into account.

Switch from sub-nodes in system-controller for each functionality to a single node representing the entire OLB instance. dt-bindings is unnecessary and soc/mobileye/mobileye,eyeq5-olb.yaml will inherit all properties.
