[Bug 797491] [NEW] overo lcd43 touchscreen does not work
You have been subscribed to a public bug:
confirmed on two kernels:
linaro 2.6.38 shipped in the 11.05 release
current 2.6.38 tip: 5983da7 Merge branch 'beagle-fixes' of git://kernel.ubuntu.com/rsalveti/linux-li
There are two DRM issues:
1) A device like Overo's lcd43 display (Samsung LTE430WQ-F0C panel) does
not support EDID probing via i2c. The DRM related code tried to account
for this but did so incorrectly.
2) The drm_mode_vrefresh function in drivers/gpu/drm/drm_modes.c is
returning a value of 59 rather than 60 which causes the code to think
the one supported more for this panel is incorrectly configured.
