2009-04-27ASoC: cs4270: add Master Playback SwitchDaniel Mack
This adds a new control named 'Master Playback Switch' for cs4270 codecs. It is implemented using the new SOC_DOUBLE_EXT macro to catch the put function and store the information about manually set mute controls from userspace. When a manual mute is set, we don't want the soc core to un-mute the outputs. Renamed cs4270_mute() to cs4270_dai_mute() to avoid confusion.

2009-03-12ASoC: Replace remaining uses of snd_soc_cnew with snd_soc_add_controls.Philipp Zabel
The drivers are basically duplicating the same code over and over. As snd_soc_cnew is going to be made static some time after the next merge window, we might as well convert them now.

2009-03-04ASoC: make ops a pointer in 'struct snd_soc_dai'Eric Miao
Considering the fact that most cpu_dai or codec_dai are using a same 'snd_soc_dai_ops' for several similar interfaces, 'ops' would be better made a pointer instead, to make sharing easier and code a bit cleaner. The patch below is rather preliminary since the asoc tree is being actively developed, and this touches almost every piece of code, (and possibly many others in development need to be changed as well). Building of all codecs are OK, yet to every SoC, I didn't test that.

2009-02-28ASoC: Add cs4270 support for slave mode configurationsDaniel Mack
Added support for scenarios where the Cirrus CS4270 audio codec is slave to the bitclk and lrclk. Mixed setups are unsupported. Signed-off-by: Daniel Mack <daniel@caiaq.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2009-02-13ASoC: add additional controls to the CS4270 codec driverTimur Tabi
Update the CS4270 codec driver to allow applications to use the mixer to control Digital Loopback, Soft Ramp, Zero Cross, Popguard, and Auto-Mute. Soft Ramp, Zero Cross, and Auto-Mute are disabled by the driver when it first initializes the hardware, but these features either don't work or interfere with normal ALSA behavior. However, they can now be re-enabled by an application if desired. Remove CONFIG_SND_SOC_CS4270_HWMUTE and always allow ASoC to control the mute bits. The driver previously and erroneously assumed that these bits control only external muting circuitry, but they also control internal muting circuitry, so they should always be used.

2009-01-30ASoC: fix initialization order of the CS4270 codec driverTimur Tabi
ASoC codec drivers typically serve two masters: the I2C bus and ASoC itself. When a codec driver registers with ASoC, a probe function is called. Most codec drivers call ASoC first, and then register with the I2C bus in the ASoC probe function. However, in order to support multiple codecs on one board, it's easier if the codec driver is probed via the I2C bus first. This is because the call to i2c_add_driver() can result in the I2C probe function being called multiple times - once for each codec. In the current design, the driver registers once with ASoC, and in the ASoC probe function, it calls i2c_add_driver(). The results in the I2C probe function being called multiple times before the driver can register with ASoC again. The new design has the driver call i2c_add_driver() first. In the I2C probe function, the driver registers with ASoC. This allows the ASoC probe function to be called once per I2C device. Also add code to check if the I2C probe function is called more than once, since that is not supported with the current ASoC design.

2009-01-23ASoC: remove stand-alone mode support from CS4270 codec driverTimur Tabi
The CS4270 supports stand-alone mode, where the codec is not connect to the I2C or SPI buses. Instead, input voltages configure the codec at power-on. The CS4270 ASoC device driver has partial support for this mode, but the code was never tested, and partial support doesn't help anyone. It also made the rest of the code more complicated than necessary.

2008-12-09ASoC: Register non-AC97 codec DAIsMark Brown
Currently this is done at module probe time since ASoC ties in codec device probe to the instantiation of the entire ASoC device. Subsequent patches will refactor the codec drivers to handle probing separately. Note that the core does not yet use this information. AC97 is special since the codec is controlled over the AC97 link but we want to give the machine driver a chance to set up the system before trying to instantiate since it may need to do configuration before the AC97 link will operate Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2008-12-01ASoC: Rename snd_soc_register_card() to snd_soc_init_card()Mark Brown
Currently ASoC card initialisation is completed by a function called snd_soc_register_card(). As part of the work to allow independant registration of cards, codecs and machines in ASoC v2 a new function of the same name has been added so rename the existing function to facilitate the merge of v2.

2008-11-21ASoC: Merge snd_soc_ops into snd_soc_dai_opsMark Brown
Liam Girdwood's ASoC v2 work avoids having two different ops structures for DAIs by merging the members of struct snd_soc_ops into struct snd_soc_dai_ops, allowing per DAI configuration for everything. Backport this change. This paves the way for future work allowing any combination of DAIs to be connected rather than having fixed purpose CODEC and CPU DAIs and only allowing CODEC<->CPU interconnections.

2008-10-30ASoC: Disable automatic volume control in the CS4270 sound driverTimur Tabi

2008-09-30ALSA: ASoC: Fix cs4270 error pathJean Delvare
The error path in cs4270_probe/cs4270_remove is pretty broken: * If cs4270_probe fails, codec is leaked. * If snd_soc_register_card fails, cs4270_i2c_driver stays registered. * If I2C support is enabled but no I2C device is found, i2c_del_driver is never called (neither in cs4270_probe nor in cs4270_remove. Fix all 3 problems by implementing a clean error path in cs4270_probe and jumping to its labels as needed.

2008-09-29ALSA: make the CS4270 driver a new-style I2C driverTimur Tabi
Update the CS4270 ALSA device driver to use the new-style I2C interface. Starting with the 2.6.27 PowerPC kernel, I2C devices that have entries in the device trees can no longer be probed by old-style I2C drivers. The device tree for Freescale MPC8610 HPCD has included an entry for the CS4270 since 2.6.25, but that entry was previously ignored by the PowerPC I2C subsystem. Since that's no longer the case, the best solution is to update the CS4270 driver to a new-style interface, rather than try to revert the behavior of new PowerPC I2C subsystem.

2008-01-31[ALSA] Remove sound/driver.hTakashi Iwai
This header file exists only for some hacks to adapt alsa-driver tree. It's useless for building in the kernel. Let's move a few lines in it to sound/core.h and remove it.

2008-01-31[ALSA] cs4270: wrong sample rate when CONFIG_SND_SOC_CS4270_VD33_ERRATA is setTimur Tabi
When CONFIG_SND_SOC_CS4270_VD33_ERRATA is set, there was a mismatch between the mclk_ratios[] and cs4270_mode_ratios[] arrays. The two arrays have been merged and code has been shuffled. One side effect is that the cs4270_set_dai_sysclk() and cs4270_set_dai_fmt() functions are available only if I2C has been enabled.

The volume control for the CS4270 ASoC driver was inverted - raising the volume level with alsamixer would decrease the actual volume.
