[alsa-devel] [PATCH v2 2.6.38] ASoC: WM8994: Ensure late enable events are processed for the ADCs
by Dimitris Papastamos 02 Mar '11

Ensure that the ADCs are provided with a clock as the previous patch "ASoC: WM8994: Improve playback robustness" did not handle this case properly.

[alsa-devel] [PATCH] audio:am3517evm support for AIC23
by Abhilash K V 01 Mar '11

01 Mar '11

This patch aims to fix the registration of the AIC23-based audio module on the AM3517-EVM, with the following two changes: 1. The i2c_board_info entry supporting aic23 codec was added into the i2c2 bus. 2. The i2c client device name (".2-001a" in this case, including the separator period) was appended to the codec_name member of am3517evm_dai to resolve the names mismatch happening in soc_bind_dai_link().
