.) The timings are correct, it behaves as if the start address has been shifted many pixels _into_ the framebuffer. This occurs whenever the display mode size is changed - using xrandr in Xorg shows that changing the resolution triggers the problem almost every time, but changing the refresh rate does not. Using devmem2 to disable and re-enable the HDLCD resolves the issue, and repeated disable/enable cycles do not make the issue re-appear. Further debugging shows that we try to update the controller configuration while enabled. Alwys ensure that the HDLCD is disabled prior to updating the controller timings, and use drm_crtc_vblank_off()/drm_crtc_vblank_on() so that DRM knows whether it can expect vblank interrupts.
