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

dt-bindings: new binding for Himax HX8357D display panels
drm: Add an hx8367d tinydrm driver.
drm/tinydrm: Fix setting of the column/page end addresses.
