When hardware design introduces significant sensor data noise,

Questions inline. Mostly around why these controls belong in DT.
What do they have to do with hardware / wiring etc rather than being
appropriate for userspace controls.
So almost all are definite no to being suitable for device tree bindings.

Hi Jonathan,
Thank you for the suggestions in your recent email. Following your
advice, I discussed these configurations in detail with engineers from
the HX9023S supplier. Based on their feedback, these settings are not
intended to be exposed to end-users. Typically, these configurations are
adjusted during the DVT phase of the end product by the supplier to
optimize performance, after which they are finalized and not meant to be
modified dynamically at the user level.
Given this approach, it seems more appropriate to provide these settings
as part of a firmware file, allowing the configuration to be kept
internal and managed without user-level access. If this approach aligns
with your thoughts, I can prepare and submit a new patch focused on
firmware parsing and handling for these configurations.
Thank you again for your valuable guidance, and I look forward to your
feedback.
Best regards,
Yasin Lee
