Adding DVI support to OMAP4 PandaBoard. PandaBoard uses TFP410 DVI Framer chip http://focus.ti.com/lit/ds/symlink/tfp410.pdf The TFP410 gets its power enable and display data over GPIO lines muxed in from OMAP4430. PandaBoard supports other LCD displays through expansion connectors, following board rework. This will disable the DVI interface. However, the existing mux settings remain the same PandaBoard additionally supports display over HDMI interface. It is mutually exclusive to display over DVI. Hence the mux settings need to be configured seperately, as and when HDMI is enabled Also, I2C3 bus used for reading EDID data from DVI Monitors is registered here. Since the design is similar to BeagleBoard, the code for the same is taken from the kernel.org commit e3333f48dd5cb21 (omap: Adding beagle i2c eeprom driver to read EDID) Reviewed-by: Manjunath G Kondaiah <redacted> Reviewed-by: Anand Gadiyar <redacted>I've also tested it on the Panda, and gone through this and most of the other patches in the series. So if you like, you could consider this an: Acked-by: Anand Gadiyar <redacted>quoted

They are available against v2.6.38-rc4 here: git://dev.omapzoom.org/pub/scm/anand/linux-omap-usb.git in the display-patches-for-v2.6.38-rc4 branch if someone wants to take a look.
These work great on my Panda A1, (mainline 2.6.38-rc4 base) haven't seen any regressions on my Beagle C4 with the same patchset/image.. Regards, -- Robert Nelson http://www.rcn-ee.com/
