Mistral OMAP3 EVM - omapdss DPI error

Hello Everyone,

I have been facing DSS init problems related to DPI interface while trying to boot a Mistral OMAP3 EVM board using kernel 2.6.35.11 (from mainline). Due to the DPI error, omapfb cannot be probed and no displays are available.

After getting kernel sources, setting "omap3_evm_defconfig", crosscompiling the sources and bootting, I have:
