OMAP4: PandaBoard: Adding DVI support
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 e3333f48 (omap: Adding beagle i2c eeprom driver to read EDID) Reviewed-by:Manjunath G Kondaiah <manjugk@ti.com> Reviewed-by:
