[alsa-devel] [PATCH 0/5] Support for OMAP4 Digital Microphone interface
by Peter Ujfalusi 23 Nov '11

23 Nov '11

Hello, The following series will add support for OMAP4 DMIC interface, and enable them on sdp4430/Blaze boards. Mark: The Panda support will be based on this series with the conversion of the sdp4430 ASoC machine driver to platform device/driver to prepare it for DT. The DT bindings for the dmic driver will be sent shortly as well.

[alsa-devel] [PATCH 1/2] ASoC: cs42l51: Clear CS42L51_MIC_POWER_CTL_AUTO bit for MODE_SLAVE and MODE_MASTER
by Axel Lin 23 Nov '11

23 Nov '11

According to the datasheet: MIC Power Control & Speed Control (Address 03h) BIT[7] : Auto-Detect Speed Mode (AUTO) Default: 1 0 - Disable 1 - Enable Function: Enables the auto-detect circuitry for detecting the speed mode of the CODEC when operating as a slave. When AUTO is enabled, the MCLK/LRCK ratio must be implemented according to Table 3 on page 39. The SPEED[1:0] bits are ignored when this bit is enabled. Speed is determined by the MCLK/LRCK ratio. SPEED[1:0] bits are ignored when this bit is enabled. Thus we need to clear this bit for MODE_SLAVE and MODE_MASTER because the default of this bit is 1 (Enable).

[alsa-devel] Commit d6cc9fabd58f33e829a3182aa856db0d57c726ef breaks built-in mic on ASUS F6A
by Dmitry Nezhevenko 23 Nov '11

23 Nov '11

Hi, I've found that internal doesn't work on kernel 3.1 while previous verison (3.0) is ok. I've bisected it between v3.0 and v3.1 using "arecord -V mono" command. It wasn't easy because of NULL pointer dereference in patch_realtek.c that was fixed by 60a6a8425a84fa46a3831ce79197640b8224311b. So during bisect I was applying applicable part of 60a6a84 for every attempt. Finally I've found that commit d6cc9fabd58f33e829a3182aa856db0d57c726ef breaks it. It's parent works well and just applying it on top breaks internal mic on my laptop. Unfortunately it's impossible to revert it on top of 3.1..
