Giving that lack of documentation, could you put some more comments in the code? so that nobody cleans out that "strange workaround" in 6 monthes...

It's not a workaround, it's how the hw works. If we'd add the explanation from the changelog everytime there's a little and/or badly documented hw oddity, you won't be able to read the code anymore.

Use git blame and dig into the history - drm/* is full of such stuff. -Daniel
