I was going to start working on making the vc4 driver work with tinydrm panels, but it turned out tinydrm didn't have the panel I had previously bought. So, last night I ported the fbtft staging driver over to DRM. It seems to work (with DT at https://github.com/anholt/linux/commits/drm-misc-next-hx8357d) -- fbdev works great including rotated, and so does modetest. However, when X11 comes up at 16bpp, I get: https://photos.app.goo.gl/8tuhzPFFoDGamEfk8 If I have tinydrm set a preferred bpp of 24, X looks great. Noralf, any ideas?
