2010-11-15ASoC: Fix dapm_seq_compare() for multi-componentMark Brown1-2/+2
Ensure that we keep all widget powerups in DAPM sequence by making the CODEC the last thing we compare on rather than the first thing. Also fix the fact that we're currently comparing the widget pointers rather than the CODEC pointers when we do the substraction so we won't get stable results.

2010-11-15ASoC: Prevent system suspend while debouncing wakeup capable GPIO jacksMark Brown1-0/+4
If the device associated with a GPIO jack is wakeup capable then disable suspend while we're debouncing the jack so that we skip suspends that race with the jack. Note that currently the GPIO based jack has a CODEC associated with it which we're using right now. These jacks should be reparented against the card itself and this code adjusted.

2010-11-11ASoC: soc-cache: Add support for rbtree based register cachingDimitris Papastamos2-1/+234
This patch adds support for rbtree compression when storing the register cache. It does this by not adding any uninitialized registers (those whose value is 0). If any of those registers is written with a nonzero value they get added into the rbtree. Consider a sample device with a large sparse register map. The register indices are between [0, 0x31ff]. An array of 12800 registers is thus created each of which is 2 bytes. This results in a 25kB region. This array normally lives outside soc-core, normally in the driver itself. The original soc-core code would kmemdup this region resulting in 50kB total memory. When using the rbtree compression technique and __devinitconst on the original array the figures are as follows. For this typical device, you might have 100 initialized registers, that is registers that are nonzero by default. We build an rbtree with 100 nodes, each of which is 24 bytes. This results in ~2kB of memory. Assuming that the target arch can freeup the memory used by the initial __devinitconst array, we end up using about ~2kB bytes of actual memory. The memory footprint will increase as uninitialized registers get written and thus new nodes created in the rbtree. In practice, most of those registers are never changed. If the target arch can't freeup the __devinitconst array, we end up using a total of ~27kB. The difference between the rbtree and the LZO caching techniques, is that if using the LZO technique the size of the cache will increase slower as more uninitialized registers get changed.

2010-11-11ASoC: soc-cache: Add support for LZO register cachingDimitris Papastamos3-1/+417
This patch adds support for LZO compression when storing the register cache. The initial register defaults cache is marked as __devinitconst and the only change required for a driver to use LZO compression is to set the compress_type member in codec->driver to SND_SOC_LZO_COMPRESSION. For a typical device whose register map would normally occupy 25kB or 50kB by using the LZO compression technique, one can get down to ~5-7kB. There might be a performance penalty associated with each individual read/write due to decompressing/compressing the underlying cache, however that should not be noticeable. These memory benefits depend on whether the target architecture can get rid of the memory occupied by the original register defaults cache which is marked as __devinitconst. Nevertheless there will be some memory gain even if the target architecture can't get rid of the original register map, this should be around ~30-32kB instead of 50kB.

2010-11-11ASoC: soc-cache: Add support for flat register cachingDimitris Papastamos3-54/+349
This patch introduces the new caching API and migrates the old caching interface into the new one. The flat register caching technique does not use compression at all and it is equivalent to the old caching technique. One can still access codec->reg_cache directly but this is not advised as that will not be portable across different caching strategies. None of the existing drivers need to be changed to adapt to this caching technique. There should be no noticeable overhead associated with using the new caching API.

2010-11-11ASoC: Add DAPM trace eventsMark Brown2-0/+126
Trace events for DAPM allow us to monitor the performance and behaviour of DAPM with logging which can be built into the kernel permanantly, is more suited to automated analysis and display and less likely to suffer interference from other logging activity. Currently trace events are generated for: - Start and stop of DAPM processing - Start and stop of bias level changes - Power decisions for widgets - Widget event execution start and stop giving some view as to what is happening and where latencies occur. Actual changes in widget power can be seen via the register write trace in soc-core. Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk>

2010-11-06ASoC: Decouple DAPM from CODECsLiam Girdwood108-1064/+1239
Decoupling Dynamic Audio Power Management (DAPM) from codec devices is required when developing ASoC further. Such as for other ASoC components to have DAPM widgets or when extending DAPM to handle cross-device paths. This patch decouples DAPM related variables from struct snd_soc_codec and moves them to new struct snd_soc_dapm_context that is used to encapsulate DAPM context of a device. ASoC core and API of DAPM functions are modified to use DAPM context instead of codec. This patch does not change current functionality and a large part of changes come because of structure and internal API changes. Core implementation is from Liam Girdwood <lrg@slimlogic.co.uk> with some minor core changes, codecs and machine driver conversions from Jarkko Nikula <jhnikula@gmail.com>.
