2011-12-30asoc: tegra: handling of i2s capture in voice call recordingNikesh Oswal
stop the enabling/disabling of i2s capture from i2s dai in voice call recording usecase because this would be handled by the voice call management functions and also add parameters for voice call record usecase in i2s structures.

2011-12-15ASoC: Tegra: Add support for AP slave mode for Tegra30Sumit Bhattacharya
If AP is set as slave set audio_sync clock as source of i2s controller clock and use pll_a_out0 as i2s controller source in AP master mode. This change is needed to support AP slave mode reliably on Tegra30.
