[PATCH 0/3] drm: tinydrm driver for adafruit PiTFT 3.5" touchscreen

[Eric Anholt]

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:

If I have tinydrm set a preferred bpp of 24, X looks great.  Noralf,
any ideas?
