Hi Josh,
We have solved the problem. It turns out that installing all the sound related *.ko did not work, installing below kos solved the problem.
sound/soc/snd-soc-core.ko
sound/soc/davinci/snd-soc-davinci.ko
sound/soc/davinci/snd-soc-evm.ko
Now ALSA listed the new card.Thanks and we appreciate your help.
Best regards,
Kishore.
