Subject: [PATCH 0/3] drm: tinydrm driver for adafruit PiTFT 3.5" touchscreen
Date: Wed, 24 Oct 2018 11:43:10 -0700 [thread overview]
Message-ID: <20181024184313.2967-1-eric@anholt.net> (raw)
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?
