[alsa-devel] [PATCH 4/4] ASoC: Davinci: Add audio codec support for DM365 EVM

[miguel.aguilar at ridgerun.com]

From: Miguel Aguilar <miguel.aguilar at ridgerun.com>

1) Enables tlv320aic3101 support on DM365 EVM.
2) Set tlv320aic3x i2c setup into DM365 EVM board file.

This patch was tested on DM365 EVM rev c.
