| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multi-component commit f0fba2ad broke a few things which this patch should fix. Tested on the DM355 EVM. I've been as careful as I can, but it would be good if those with access to other Davinci boards could test. -- The multi-component commit put the initialisation of snd_soc_dai.[capture|playback]_dma_data into snd_soc_dai_ops.hw_params of the McBSP, McASP & VCIF drivers (davinci-i2s.c, davinci-mcasp.c & davinci-vcif.c). The initialisation had to be moved from the probe function in these drivers because davinci_*_dai changed from snd_soc_dai to snd_soc_dai_driver. Unfortunately, the DMA params pointer is needed by davinci_pcm_open (in davinci-pcm.c) before hw_params is called. I have moved the initialisation to a new snd_soc_dai_ops.startup function in each of these drivers. This fix indicates that all platforms that use davinci-pcm must have been broken and need to test with this fix. -- The multi-component commit also changed the McBSP driver name from "davinci-asp" to "davinci-i2s" in davinci-i2s.c without updating the board level references to the driver name. This change is understandable, as there is a similarly named "davinci-mcasp" driver in davinci-mcasp.c. There is probably no 'correct' name for this driver. The DM6446 datasheet calls it the "ASP" and describes it as a "specialised McBSP". The DM355 datasheet calls it the "ASP" and describes it as a "specialised ASP". The DM365 datasheet calls it the "McBSP". Rather than fix this problem by reverting to "davinci-asp", I've elected to avoid future confusion with the "davinci-mcasp" driver by changing it to "davinci-mcbsp", which is also consistent with the names of the functions in the driver. There are other fixes required, so it was never going to be as simple as a revert anyway. -- The DM365 only has one McBSP port (of the McBSP platforms, only the DM355 has 2 ports), so I've changed the the id of the platform_device from 0 to -1. -- In davinci-evm.c, the DM6446 EVM can no longer share a snd_soc_dai_link structure with the DM355 EVM as they use different cpu DAI names (the DM355 has 2 ports and the EVM uses the second port, but the DM6446 only has 1 port). This also means that the 2 boards need different snd_soc_card structures. -- The codec_name entries in davinci-evm.c didn't match the i2c ids in the board files. I have only checked and fixed the details of the names used for the McBSP based platforms. Someone with a McASP based platform (eg DA8xx) should check the others.

The name collision would occur when codec drivers try to registering kcontrols with the same name or when building audio paths. This patch introduces optional prefix_map into struct snd_soc_card. With it machine drivers can specify a unique name prefix to each codec that have conflicting names with anothers. Prefix to codec is matched with codec name. Following example illustrates a machine that has two same codec instances. Name collision from kcontrol registration is avoided by specifying a name prefix "foo" for the second codec. As the codec widget names are prefixed then second audio map for that codec shows a prefixed widget name. static const struct snd_soc_dapm_route map0[] = { {"Spk", NULL, "MONO"}, }; static const struct snd_soc_dapm_route map1[] = { {"Vibra", NULL, "foo MONO"}, }; static struct snd_soc_prefix_map codec_prefix[] = { { .dev_name = "codec.2", .name_prefix = "foo", }, }; static struct snd_soc_card card = { ... .prefix_map = codec_prefix, .num_prefixes = ARRAY_SIZE(codec_prefix), }; Signed-off-by: Jarkko Nikula <jhnikula@gmail.com> Acked-by: Liam Girdwood <lrg@slimlogic.co.uk> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>

* | ASoC: soc-cache: Add support for rbtree based register cachingDimitris Papastamos2010-11-111-0/+232
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | ASoC: soc-cache: Add support for LZO register cachingDimitris Papastamos2010-11-112-0/+415
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | Instead of dereferencing a NULL function pointer and falling apart use BUG_ON() for any unimplemented hw_read() calls.

| * ASoC: WM8776: Removed unneeded struct memberDimitris Papastamos2010-11-061-1/+0
| | | | | | | | | | | | | | | | | | | | | | The member reg_cache is not used at all and therefore it should be removed. This member was usually needed for older versions of ASoC that did not handle caching automatically and had to be done in the driver itself.

* | ASoC: Move pop time from DAPM context to sound cardJarkko Nikula2010-11-063-25/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | Based on discussion the dapm_pop_time in debugsfs should be per card rather than per device. Single pop time value for entire card is cleaner when the DAPM sequencing is extended to cross-device paths. debugfs/asoc/{card->name}/{codec dir}/dapm_pop_time -> debugfs/asoc/{card->name}/dapm_pop_time Signed-off-by: Jarkko Nikula <jhnikula@gmail.com> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
