2009-07-22ASoC: MAX9877: separate callback functionsJoonyoung Shim1-33/+63
The callback function to control register was used by whole controls in MAX9877 driver, but this causes using many if statement for double register control or invert. So, the callback function for double register control is separate differently, and the code for invert is added in the callback function.

2009-07-22ASoC: MPC5200: Increase the delay time between resetsJohn Bonesio1-1/+2
Reset was failing with the original udelay(50) between the code in psc_ac97_cold_reset() and the call to psc_ac97_warm_reset(). Through testing it was found that a delay of 1ms was necessary for the cold_reset code to consistently complete successfully.

2009-07-17ASoC: SDP3430: Add support for EXTMUTE using TWL GPIO6Candelaria Villareal, Jorge1-0/+9
Board sdp3430 has hardware support for EXTMUTE using TWL4030 GPIO6 line, controlled by register INTBR_PMBR1. Machine driver takes care of enabling gpio line through i2c and codec driver manipulates the line during headset ramp up/down sequence.

2009-07-15ASoC: MAX9877: add MAX9877 amp driverJoonyoung Shim4-0/+318
The MAX9877 combines a high-efficiency Class D audio power amplifier with a stereo Class AB capacitor-less DirectDrive headphone amplifier. The max9877_add_controls() is called to register the MAX9877 specific controls on machine specific init() of the machine driver.

2009-07-08ASoC: Configure WM8731 SYSCLK at startup on AT91SAM9G20-EKMark Brown1-25/+10
The system clock is currently fixed by the driver and this avoids the need for us to handle errors with enabling and disabling MCLK (which was incorrect previously so this fixes bugs in error handling). Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-07-08ASoC: Disable microphone input for AT91SAM9G20-EK by defaultMark Brown1-1/+13
As shipped the board does not have inputs but it is relatively straightforward to modify the board to hook them up so support is provided in the driver. When these modifications have not been made enabling the microphone stage can cause problems. Add an ifdef to disable this by default. Don't put it into Kconfig since users will have to get their soldering irons out to change things. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-07-08ASoC: Use CODEC as clock master on AT91SAM9G20-EKMark Brown1-87/+2
This simplifies the driver by removing the need to manually configure dividers within the CPU and improve audio performance by ensuring that the optimal phase relationships between the clocks in the system are maintained. Note that currently this means that for playback to work the Output Mixer HiFi switch must be enabled since otherwise CODEC will not generate the DAC clock.

2009-07-08ASoC: Limit WM8731 to symmetric ratesMark Brown1-0/+1

2009-07-05ASoC: Remove use of hw_read from TLV320AIC3x driverMark Brown1-9/+2
The TLV320AIC3x driver is currently the only user of the CODEC hw_read operation and is jumping through some hoops in order to do so. In order to support future refactoring to make the hw_read operation more usable unwrap the usage in this driver to avoid its use. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-07-05ASoC: Remove unused AK4535 hardware read functionalityMark Brown1-16/+0
Nothing uses it and the existing hw_read operation needs to be refectored so it's easier to remove it rather than work with it. Support can be re-added if the code requires volatile registers. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-07-05ASoC: Begin to factor out register cache I/O functionsMark Brown10-577/+400
A lot of CODECs share the same register data formats and therefore replicate the code to manage access to and caching of the register map. In order to reduce code duplication centralised versions of this code will be introduced with drivers able to configure the use of the common code by calling the new snd_soc_codec_set_cache_io() API call during startup. As an initial user the 7 bit address/9 bit data format used by many Wolfson devices is supported for write only CODECs and the drivers with straightforward register cache implementations are converted to use it.
