Auto-detection was enabled by default in the original driver so I think that should be left intact. I added the ability to manually override this via DT with a fixed value, and then configure said fixed value through sysfs at runtime. I'm not 100% clear on the usecase of runtime enabling/disabling auto so I'd rather leave the implementation as-is. Either auto mode is enabled or not -- and this is directly tied to the DT setting. But if someone has a strong usecase for this I can certainly add it.
