* ASoC: Factor out I2C 8 bit address 16 bit data I/OMark Brown2009-08-03
| | | | | | | As part of this refactoring the type of the CODEC hw_read operation is changed to match the regular read operation. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* ASoC: Add I/O control bus information to factored out cache setupMark Brown2009-08-03
| | | | | | | | | | | While writes tend to be able to use a fairly bus independant format to do the writes reads are all bus specific. To allow us to factor out this code include the bus type as a parameter when setting up the cache. Initially just use this to factor out hw_write_t for I2C.

| * ASoC: Remove use of hw_read from TLV320AIC3x driverMark Brown2009-07-05
| | | | | | | | | | | | | | | | | | 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>
| * ASoC: Remove unused AK4535 hardware read functionalityMark Brown2009-07-05
| | | | | | | | | | | | | | | | 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>
* | ASoC: Factor out WM8580 register cache codeMark Brown2009-07-05
| | | | | | | | | | | | | | Note the slightly tricky cache usage in the volume update function due to the requirement for a separate write for the VU bit. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
* | ASoC: Begin to factor out register cache I/O functionsMark Brown2009-07-05
|/ | | | | | | | | | | | | | | | 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.

* ASoC: Zoom2: Update twl4030_setup_data parametersCandelaria Villareal, Jorge2009-07-03
| | | | | | | | | | | | | | Add support for EXTMUTE in Zoom2 machine driver. This is necessary to further reduce pop noise problem. Signal EXTMUTE is connected to signal GPIO 153 in Zoom2 board. In addition, change ramp delay value to 3 (218/161/109 ms). With previous ramp delay value, pop noise was louder. With a longer value the beep tone can be observed.

* ASoC: TWL4030: Add EXTMUTE to reduce pop-noise effectCandelaria Villareal, Jorge2009-07-02
| | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch tries to work around the problem of broken OMAP1510 PCM playback pointer calculation by replacing DMA function call that incorrectly tries to read the value form DMA hardware with a value computed locally from an already maintained variable omap_runtime_data.period_index.

Similarly, the I2C device registration temporarily moves into the magician machine driver before it will find its final resting place in the board file. At the same time, platform specific configuration is moved to platform data and common power/reset GPIO handling moves into the codec driver.

| * | | ASoC: Add stub suspend and resume calls for ASoC subdevicesMark Brown2009-06-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now that ASoC subdevices can be regular devices they can have normal suspend and resume calls from their buses. However, suspending them individually is not desirable since this can lead to problems such as pops and clicks from devices being suspended with their signals being amplified or clocks being stopped suddenly. This will be resolved by having the normal device model suspend and resume calls call into ASoC which will suspend the entire card while any of its components are suspended. At present this is not yet implemented but in order to aid the transition of drivers to the standard device model this patch adds API calls for the notifications.
