Unfortunately I can't. In fact we have a few DM81xx devices which boot
nicely using the existing kernel code and have most of the peripherals
working fine, but sound is not working even though all the relevant
drivers are in place. I believe that unless davinci-evm is deprecated,
it is beneficial for everyone to have it supporting DM81xx (and I can
take over its maintenance since the current maintainer has invalid
e-mail specified in the header). I'll be working on of-graph version,
too, but Rome wasn't built in a day, you know :)

Best regards,
