What I said before: "Again, third time (once from Bjorn, once from Dmitry), rephrase property name and description to describe the hardware issue. I see description improved, but not the property name. Again in the end of description you say what Linux should do. Bindings do not describe Linux OS."You didn't answer my question: "I see a plenty of properties similar to this one instructing the OS to keep some resource ON to workaround hardware issues. So they are all wrong?"They are not the best, but it all depends on the individual case.quoted
If you say they are wrong, why are they approved in the first place?Because we don't have time to keep digging what the driver is doing and what is claimed in DT. Some people don't even CC us on the driver.Not sure if I asked this before, but can this not be set in the config struct inside the driver?This cannot be the default config for any platform as keeping refclk always on will have some power penalty. Only if the hardware (EP or board design) has any issue, we can turn on this option.
So, if I'm reading this right, this concerns some but not all 8280 boards? Konrad -- linux-phy mailing list linux-phy@lists.infradead.org https://lists.infradead.org/mailman/listinfo/linux-phy
