You are describing a transitioning over to DRM - which is Ok. But on that way there is no need to ignore, deny or even kill usage scenarios which are different compared to your usage scenarios (e.g. embedded devices, old platforms, slow devices, slow busses, no 3D hardware features, low-color devices, ...).
All of those should be handled by the drm layer, as Daniel keeps pointing out. If not, then the tinydrm layer needs to be enhanced to do so.
Anyone have a pointer to hardware I can buy that is one of these fbtft drivers that I could do a port to drm to see just how much work is really needed here?
I have bought myself (for other purposes, I mean not to convert the driver(s)) SSD1306 based display (SPI), SSD1331 (SPI), HX88347d (parallel).
Each of them costed less than $10 with delivery to EU (nowadays maybe a bit more expensive). I believe it's very easy to find the links on AliExpress.
