[alsa-devel] [PATCH 0/8] ASoC: OMAP-twl4030: Add support for more3 boards
Hello,
This series will update the omap-twl4030 machine driver and the twl4030 codec driver to enable support for more boards. With this change we can remove two more machine drivers: zoom2 and sdp3430 since they will be supported by the common omap-twl4030 machine driver. The arch/arm/mach-omap2/ patches will go as a separate series to avoid cross tree issues.
Regards, Peter --- Peter Ujfalusi (8): ASoC: twl4030: Correct the support for Voice port ASoC: zoom2: No need to configure the Voice port anymore ASoC: sdp3430: No need to configure the Voice port anymore ASoC: twl4030: Convert MICBIAS to SUPPLY widget ASoC: twl4030: Configure extmute pinmux when the dedicated pin is in use ASoC: sdp3430: No need to configure pin mux for extmute ASoC: omap-twl4030: Add support for routing, voice port and jack detect ASoC: OMAP: Remove obsolete machine drivers for Zoom2 and SDP3430

In order to be able to use the Voice port of twl4030 three bits need to be handled in VOICE_IF register: VIF_EN: to enable the voice port (needed for both playback and capture) VIF_DIN_EN: Need to be enabled for playback only (input to the codec) VIF_DOUT_EN: Need to be enabled for capture only (output from codec)
Use DAPM_SUPPLY for the VIF_EN bit and add DAPM_AIF_IO/OUT widget to handle the playback/capture bit.

Applied all, thanks.

When HS extmute is enabled without custom GPIO we should configure the mux to allow the pin to be used as extmute signal.
