Currently the ASoC core configures the bias levels in the system using a callback on codecs and machines called 'dapm_event', passing it PCI style power levels as SNDRV_CTL_POWER_ constants. This is more obscure than it needs to be and has caused confusion to driver authors, especially given that DAPM is also performing power management. Address this by renaming the callback function to 'set_bias_level' and using constants explicitly representing the off, standby, pre-on and on states which DAPM transitions through. Also unexport the API for setting bias level: there are currently no in-tree users of this API other than the core itself and it is likely that the core would need to be extended to cater for any users.

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. With this patch, sound/driver.h isn't removed but has just a single compile warning to include it. This should be really killed in future.

This patch fixes a bug whereby AC97 bus device data was being clobbered when AC97 codecs using the generic ac97_codec.c driver were being registered. Codecs that didn't use the generic driver were unaffected (e.g. WM9712, WM9713). Changes:- o Add new AC97 codec class for custom (or need bus dev registration) AC97 codecs. o Only register/deregister this custom codec device with the AC97 bus. The generic AC97 driver already does this for generic codec devices.

This patch updates the ASoC core to the new DAI matching and clocking API in version 0.13 Changes:- o Removed DAI capabilities matching code in favour of manual matching in the machine drivers. o Added DAI operations for codec and CPU interfaces. o Removed config_sysclk() function and struct snd_soc_clock_info. No longer needed as clocking is now configured manually in the machine drivers. Also removed other clocking data from structures. o Added machine driver prepare callback.

This patch fixes a bug whereby the power management delayed work would never be run at driver suspend() or module remove(). Delayed work would be created (after audio had finished) with a long delay (~5 secs) and was sometimes never queued before flush_scheduled_work() was being called at suspend or module remove. This caused the delayed work to queued after the module had been removed or after resume. This patch forces any delayed work to complete by cancelling it (timer cannot fire and add it to queue later), scheduling it for now and waiting on it's completion. This is something I probably would like to add to workqueue.c in the next merge window, however it's here atm because it can oops.

From: Andrew Morton <akpm@osdl.org> I converted the workqueues to per-device while I was there. It seems strange to create a new kernel thread (on each CPU!) and to then only have a single global work to ever be queued upon it. Plus without this, I'd have to use the _NAR stuff, gawd help me. Does that workqueue really need to be per-cpu? Does that workqueue really need to exist? Why not use keventd?

This patch adds support for the DAI BCLK to be generated by multiplying Rate * Channels * Word Size (RCW). This now gives 3 options for BCLK clocking and synchronisation :- 1. BCLK = Rate * x 2. BCLK = MCLK / x 3. BCLK = Rate * Chn * Word Size. (New) Changes:- o Add support for RCW generation of BCLK o Update Documentation to include RCW. o Update DAI documentation for label = value DAI modes. o Add RCW support to wm8731, wm8750 and pxa2xx-i2s drivers.

This patch is the core of ASoC functionality. The ASoC core is designed to provide the following features :- o Codec independence. Allows reuse of codec drivers on other platforms and machines. o Platform driver code reuse. Reuse of platform specific audio DMA and DAI drivers on different machines. o Easy I2S/PCM digital audio interface configuration between codec and SoC. Each SoC interface and codec registers their audio interface capabilities with the core at initialisation. The capabilities are subsequently matched and configured at run time for best power and performance when the application hw params are known. o Machine specific controls/operations: Allow machines to add controls and operations to the audio subsystem. e.g. volume control for speaker amp. To achieve all this, ASoC splits an embedded audio system into 3 components :- 1. Codec driver: The codec driver is platform independent and contains audio controls, audio interface capabilities, codec dapm and codec IO functions. 2. Platform driver: The platform driver contains the audio dma engine and audio interface drivers (e.g. I2S, AC97, PCM) for that platform. 3. Machine driver: The machine driver handles any machine specific controls and audio events. i.e. turning on an amp at start of playback.
