From 8f6ac18808eb88377e62a3ebee9edfb25d5fcb32 Mon Sep 17 00:00:00 2001 From: Stephen Warren Date: Wed, 14 Aug 2013 14:24:16 -0600 Subject: [PATCH] ASoC: tegra: fix Tegra30 I2S capture parameter setup The Tegra30 I2S driver was writing the AHUB interface parameters to the playback path register rather than the capture path register. This caused the capture parameters not to be configured at all, so if capturing using non-HW-default parameters (e.g. 16-bit stereo rather than 8-bit mono) the audio would be corrupted. With this fixed, audio capture from an analog microphone works correctly on the Cardhu board.
