The board where this > patches are useful is not yet upstream but will be soon (hopefully). Tell us more. My initial instinct is that this shouldn't be board specific. What's the trade off we are making here? Time vs precision of calibration or something else? If these are set to a level by default that doesn't work for our board, maybe we should just change them for all devices?
