Seems like v5 (patch at least, I did not look at the rest) does not address a handful of the feedback. - Access registers via readl/writel, instead of current approach - With ^^ you can drop the compiler workaround - Checking for unsupported KMS properties (format, rotation, etc) should happen in the XXX_check callbacks - Remove always true checks, around the (rather moot) abstraction layer
For the future, please keep the revision/changelog within the corresponding patch. This way reviewers can see, from the onset, what is addressed. Look at `git log -- drivers/gpu/drm` for examples.
