2009-07-02ASoC: TWL4030: Add EXTMUTE to reduce pop-noise effectCandelaria Villareal, Jorge
According to TRM, an external FET controlled by a 1.8V output signal can be used to reduce the pop-noise heard when the audio amplifier is switched on. It is suggested that GPIO6 of TWL4030 be used, but any other gpio can be used instead. This is indicated in machine driver with the following twl4030_setup_data members: -hs_extmute. Set to 1 if board has support for EXTMUTE. -set_hs_extmute. Set to a callback funcion to control an external gpio line. Set to NULL if MUTE[GPIO6] pin is used. Codec driver takes care of enabling and disabling this output during the headset pop attenuation sequence. Also add a delay to let VMID settle in ramp up sequence.

2009-05-22ASoC: TWL4030: Add support for platform dependent configurationPeter Ujfalusi
twl4030_setup_data structure can be passed from platform drivers to the codec via the snd_soc_device->codec_data pointer. Currently the setup data has support for the Headset pop-removal related configuration, which differs from board to board.

Support for 4 channel TDM (SND_SOC_DAIFMT_DSP_A) for twl4030 codec. The channel allocations are: Playback: TDM i2s TWL RX Channel 1 Left SDRL2 Channel 3 Right SDRR2 Channel 2 -- SDRL1 Channel 4 -- SDRR1 Capture: TDM i2s TWL TX Channel 1 Left TXL1 Channel 3 Right TXR1 Channel 2 -- TXL2 Channel 4 -- TXR2 Signed-off-by: Peter Ujfalusi <peter.ujfalusi@nokia.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-04-20ASoC: TWL4030: Add support Voice DAIJoonyoung Shim
Add Voice DAI to support the PCM voice interface of the twl4030 codec. The PCM voice interface can be used with 8-kHz(voice narrowband) or 16-kHz(voice wideband) sampling rates, and 16bits, and mono RX and mono TX or stereo TX. The PCM voice interface has two modes - PCM mode1 : This uses the normal FS polarity and the rising edge of the clock signal. - PCM mode2 : This uses the FS polarity inverted and the falling edge of the clock signal. If the system master clock is not 26MHz or the twl4030 codec mode is not option2, the voice PCM interface is not available.

2009-01-29ASoC: TWL4030: Add analog loopback supportPeter Ujfalusi
This patch adds the analog loopback/bypass support for twl4030 codec. Details for the implementation: It seams that the analog loopback needs the DAC powered on on the channel, where the loopback is selected. The switch for the DACs has been moved from the DAPM_DAC to the "Analog XX Playback Mixer". In this way the DAC will be powered while the audio playback is used or/and the loopback is enabled for the channel. The twl4030 codec powering has been reworked. Now the codec will be powered as long as it does not receives the SND_SOC_BIAS_OFF event. The exceptions are when the given change in the registers needs the codec power down/up cycle in order to take effect. Otherwise the codec is on. When the codec enters to STANDBY state and none of the loopback paths are enabled, than the amplifiers, which are no in the DAPM path are forced to turn off and the PLL is disabled. When playback/capture starts the disabled gains are restored and the PLL is enabled. When one of the loopback enabled in STANDBY mode, the disabled gains are restored and the PLL is enabled also. In short: the codec always goes to the lowest power state based on the bias_level and the bypass_state.

2008-12-31ASoC: TWL4030: DAPM based capture implementationPeter Ujfalusi
This patch adds DAPM implementaion for the capture path on twlx030. TWL has two physical ADC and two digital microphone (stereo) connections. The CPU interface has four microphone channels. For simplicity the microphone channel paths are named as: TX1 (Left/Right) - when using i2s mode, only the TX1 data is valid TX2 (Left/Right) Input routing (simplified version): There is two levels of mux settings for TWL in input path: Analog input mux: ADCL <- {Off, Main mic, Headset mic, AUXL, Carkit mic} ADCR <- {Off, Sub mic, AUXR} Analog/Digital mux: TX1 Analog mode: TX1L <- ADCL TX1R <- ADCR TX1 Digital mode: TX1L <- Digimic0 (Left) TX1R <- Digimic0 (Right) TX2 Analog mode: TX2L <- ADCL TX2R <- ADCR TX2 Digital mode: TX2L <- Digimic1 (Left) TX2R <- Digimic1 (Right) The patch provides the following user controls for the capture path: Mux settings: "TX1 Capture Route": {Analog, Digimic0} "TX2 Capture Route": {Analog, Digimic1} "Analog Left Capture Route": {Off, Main Mic, Headset Mic, AUXL, Carkit Mic} "Analog Right Capture Route": {Off, Sub Mic, AUXR} Volume/Gain controls: "TX1 Digital Capture Volume": Stereo gain control for TX1 path "TX2 Digital Capture Volume": Stereo gain control for TX2 path "Analog Capture Volume": Stereo gain control for the analog path only Important things for the board files: Microphone bias: "Mic Bias 1": Bias for Main mic or for digimic0 (analog or digital path) "Mic Bias 2": Bias for Sub mic or for digimic1 (analog or digital path) "Headset Mic Bias": Bias for Headset mic When the routing configured correctly only the needed components will be powered/enabled.

2008-12-03ASoC: TWL4030: Add input selection and gain controlsGrazvydas Ignotas
The TWL4030 codec device has two ADCs. Both of them can have several inputs routed to them, but TRM says that only one source can be selected for every ADC, even though every source has a dedicated bit in the registers. This patch adds input source controls. It modifies default register values to have no inputs selected and ADCs disabled. When some input is selected, control handlers enable apropriate input amplifier and ADC. If a microphone is selected, bias power is automatically enabled. When some input is deselected, unused chip parts are disabled. Microphone and line input recording tested on OMAP3 pandora board.
