Since we got a maintainer for fbdev, I would like to unorphan fbtft (with the idea of sending PRs to Helge) and move it out of staging since there is no more clean up work expected and no more drivers either.
Thoughts?
Thanks for sharing yours, my answers below.
But why? We already have DRM drivers for some of these devices.
No, we do not (only a few are available).
Porting the others to DRM is such a better long-term plan. OTOH, as no one has shown up and converted them, maybe they should be left dead or removed entirely.
As I mentioned above there are devices that nobody will take time to port to a way too complex DRM subsystem. But the devices are cheap and quite widespread in the embedded world. I'm in possession of 3 or 4 different models and only 1 is supported by tiny DRM.
On top of that the subtle fact people forgot about FBTFT is that it does support parallel interface (yes, I know that it's not performant, but one of the displays I have is with that type of interface).
P.S. For the record, I will personally NAK any attempts to remove that driver from the kernel. And this is another point why it's better not to be under the staging.
