Re: [ 7.092803] omapdss error: timeout reading edid

Besides the 4460 board I also have a brand new 4430 pandaboard. It
displays the same behaviour as Thorsten's (EDID timeout) when exchanged
for the 4460. So I suspect a software problem behind the failure to read
EDIDs.

Is there an easy way to determine if (omap_rev() > OMAP4430_REV_ES2_2)
delivers TRUE in affected 4430 boards?

Title:
  Panda: only low resolution on 1080p plasma

Status in Linaro Texas Instruments Landing Team:
  Confirmed
Status in Linaro Ubuntu Evaluation Builds:
  Confirmed

Bug description:
  Installed the linarotv image 20120114-2 and hwpack_linaro-lt-panda-x11-base_20120106-1 on a Pandaboard ES with linaro-media-create.
  After boot installed ubuntu-omap4-extras-multimedia.
  Then did a dist-upgrade on Jan 21. 20:45CET

  HDMI connected to a Yamaha RX-V1800 audio-video-receiver and from
  there to a 1080p plasma TV.

  The resulting screen resolution was only 720×576@50 and xbmc does not offer any further resolutions or refresh rates.
  The EDID sent by the Yamaha AVR includes many resolutions up to 1080p (verified with SwitchResX on a MacBook).

  Attached boot log with options omapdss.debug=1 drm.debug=7 and EDID
