This cannot be discussed until the UAPI contract is drafted. It needs to end up in the appropriate "Properties" section under https://dri.freedesktop.org/docs/drm/gpu/drm-kms.html#kms-properties when documentation is built. I also do not see any of the previous review comments being addressed that I recall. The typo "sharpeness" is very common in these patches, and it is even in the UAPI as the property name. Also doc comments use different spelling than actual code. And sometimes you use even "sharpening" instead of "sharpness". Which one is it?
