Success!
I installed fbdev (2:0.4.2-r17.0.12):
opkg install xf86-video-fbdev
I then enabled fbdev in X11 by editing the "Device" section of
/etc/X11/xorg.conf to:
Section "Device"
Identifier "Builtin Default fbdev Device 0"
Driver "fbdev"
Option "Rotate" "CCW"
EndSection
That rotated the screen, but the touchscreen needed to swap x and y, and
invert x, so I added two Options to the "evdev touchscreen catchall"
identifier of /usr/share/X11/xorg.conf.d/10-evdev.conf:
Section "InputClass"
Identifier "evdev touchscreen catchall"
MatchIsTouchscreen "on"
MatchDevicePath "/dev/input/event*"
Driver "evdev"
Option "SwapAxes" "true"
Option "InvertX" "true"
EndSection
Which worked for the base X server (clock face pointer and login screen),
but as soon as the default user logged in, the touchscreen lost its swap
axes option. I could run:
xinput --set-prop "ti-tsc" "Evdev Axes Swap" 1
from an xterm window, to get it to work again, but I wanted it to be
automatic.
At first I tried adding it to the .xprofile file, but that didn't work. I
then found that by modifying /etc/pointercal.xinput to the following:
xinput set-int-prop "ti-tsc" "Evdev Axis Calibration" 32 3733 367 79
3992;xinput
set-int-prop "ti-tsc" "Evdev Axes Swap" 8 1;
everything worked on a reboot.
Thanks for your help, Gary. I wish it would have worked with modesetting
and xrandr, but I will leave that as an exercise for another user :)
And for the HDMI vs LCD driver, as far as I know, the base (internal to the
AM33xx) lcd controller is used for both. I looked at the source dts file
for HDMI and it defines a similar fb section as the LCD7 dts file. But, at
this point, I don't need to dig any deeper....
