From 8d43d1bc81190ee8e4e694d805afa586339b0afc Mon Sep 17 00:00:00 2001 From: Chaithrika U S Date: Wed, 10 Mar 2010 14:48:33 +0530 Subject: ASoC: DaVinci: Add hw_param callback for S/PDIF DIT link On TI DM6467 EVM, S/PDIF DIT codec fails to open as it is unable to install hardware params. This dummy codec has no set_fmt and set_sysclk implementations and calls from the application to these functions cause errors. This patch adds a new hardware params callback function for S/PDIF transciever codec.

However, the current soc-core doesn't support simultaneous codecs, once that support will have added, a patch will be posted to enable both codecs in the DM365 EVM.
