2012-12-10ASoC: Samsung: remove __dev* attributesBill Pemberton
CONFIG_HOTPLUG is going away as an option. As result the __dev* markings will be going away. Remove use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit. Signed-off-by: Bill Pemberton <wfp5p@virginia.edu> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2012-12-07ASoC: Samsung: Do not register samsung audio dma device as pdevPadmavathi Venna
Previously, the ASoC 'platform' (PCM/DMA) object was instantiated via a platform_device. This didn't represent the hardware well, since there was no separate hardware associated with this platform_device; it was a virtual device with sole purpose to call snd_soc_register_platform(). This change removes the platform_device completely. Each Samsung DAI now registers the ASoC 'platform' itself. Machine drivers are adjusted for the new 'platform' name.

2011-10-31sound: Add module.h to the previously silent sound usersPaul Gortmaker

2011-08-31ASoC: Allow source specification for CODEC level sysclkMark Brown
Similarly to PLLs/FLLs some modern CODECs provide selectable system clock sources. When the clock is the clock for a DAI we do not usually need to identify which clock is being configured so can use clk_id for the source clock but with CODEC wide system clocks we will need to specify both the clock being configured and the source. Add a source argument to the CODEC driver set_sysclk() operation to reflect this. As this operation is not as widely used as the DAI set_sysclk() operation the change is not very invasive. We probably ought to go and make the same alternation for DAIs at some point. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-08-12ASoC: Allow userspace control of Speyside headphone outputMark Brown

2011-06-06ASoC: Manage Speyside system clocking only in bias managementMark Brown
Now that the CODEC driver supports it defer configuration of the system clock until bias management which is a much more idiomatic place to do system power control and makes things a lot more happy when we're using both interfaces.

2011-04-13ASoC: Mark Speyside widgets as ignoring suspendMark Brown

2011-04-13ASoC: Add stub baseband link on SpeysideMark Brown
Demonstrate the connection of a baseband to the system. We add a DAI for the link to the baseband. This will become visible to the application layer - audio should be started from the application layer using an application such as this: http://opensource.wolfsonmicro.com/~gg/bluetooth-pcm/bluetooth_pcm.c which starts up audio as for CPU based playback and record up to the point where data is streamed. Due to non-availability of baseband simulation hardware we reuse the configuration for the CPU link with the CODEC acting as clock master, allowing signals to be observed with a scope. A more standard system would have separate configuration for the baseband with its own ops structure and operations. Normally the baseband would be clock master as the baseband audio will be synchronised to the external telephony network.

2011-04-13ASoC: Add pin switches for fixed analogue inputs and outputs on SpeysideMark Brown
Pin switches enable direct control of the DAPM state from userspace, enabling simple enabling and disabling of the path. This is especially useful for outputs such as the speaker which are composed of several physical devices as it allows them to be controlled as a group.

2011-04-13ASoC: Add Speyside headset jack detection supportMark Brown
Speyside makes use of support the WM8915 has for detecting the polarity of the microphone and ground connections on headsets, using a GPIO to control the polarity of the ground connection and switching between the two microphone bias supplies available on the device in order to do so. As a result of this the detection support is more involved than for most other CODECs, using a callback to configure the current polarity of the jack and translate this into the board-specific connections required for the current scenario. On Android some additional work is required to hook this up to the application layer as the Android HeadsetObserver monitors a custom drivers/switch API rather than the standard Linux APIs. This can be done by either updating HeadsetObserver or modifying the ALSA core to report via drivers/switch as well.

2011-04-13ASoC: Support the sub speaker driver on SpeysideMark Brown
Speyside includes a WM9081 configured as an external speaker driver taking an analogue input from HPOUT2 on the WM8915 on the system. Add support for this to the driver, using a prefix of "Sub" for the WM9081 controls to ensure we avoid collisions with controls on the WM8915.

2011-04-13ASoC: Initial audio support for Speyside on Cragganmore 6410Mark Brown
This is minimal code required to get audio out of the Speyside audio subsystem on the Wolfson Cragganmore 6410 reference platform. It sets up the link between the CPU and AIF1 of the WM8915 on the system, enabling audio playback via the headphone and speaker outputs of the device (which require no further configuration except runtime). It allows verification of basic functionality of the system.
