On OpenMoko soc-audio resume is taking 700ms of the whole resume time of 1.3s, dominated by writes to the codec over I2C. This patch shunts the resume guts into a workqueue which then is done asynchronously. The "card" is locked using the ALSA power state APIs as suggested by Mark Brown. [Added fix for race with resume to suspend and fixed a couple of nits from checkpatch -- broonie.] Signed-off-by:

To provide added robustness in case an AC97 controller reads back all zeros in error cases check for an exact match when testing to see if resets have brought the codec back. Signed-off-by:

Sort stac9205_cfg_table in the order of id numbers, and removed the duplicated (obsoleted) entries for 0x01fc and 0x01fd. This doesn't change the driver behavior since the old entries are all secondary. The duplication occured due to commit dfe495d0, and the old entries were introduced by commit ae0a8ed8. Signed-off-by:

ASoC codec drivers frequently set the register cache size using sizeof() rather than ARRAY_SIZE(). For tlv320aicx either is correct since the registers are 8 bit but update to use ARRAY_SIZE() for clarity. Signed-off-by:

The register cache size is used by the codec_reg sysfs file which works in terms of the register cache access functions rather than in terms of raw access to the cache so the size specified needs to be in terms of the number of elements. Signed-off-by:

The pending IRQ handling is a very hackish workaround and should be avoided as much as possible via a larger bdl_pos_adj option value. Put a warning message if this situation occurs so that the user may have a chance to notice that something is wrong. Signed-off-by:

ATI SB controllers seem to report the DMA ahead in the amount of FIFO. Thus bdl_pos_adj should be 32 for them as default. Also, the default value is set to -1, which means to make the driver to choose the appropriate value. Signed-off-by:

The option bdl_pos_adj should be provided for each card instance instead of a global one because the value depends rather on each controller-chip. Signed-off-by:

position_fix=3 is the option to correct the DMA position with the FIFO size. But, it never worked correctly, and we have now more other workarounds for the DMA position fixes. Thus better to remove it. Also, change POS_FIX_NONE to POS_FIX_LPIB to represent its real role better. Signed-off-by:

Added a new option, bdl_pos_adj, to adjust the delay of IRQ-wakeup timing. Most HD-audio hardwares have a problem that a BDL IRQ is issued before actually the data and the DMA pointer are updated. We have already a mechanism to force to delay snd_pcm_period_elapsed() calls via workq, but this costs much CPU, and typically the delay is within one sample. Thus, it's more clever to adjust the BDL entries instead. The new option adds the size of the delay in frames. As default, it's set to 1 -- that is, one sample delay. Even the hardware is really correct, one sample delay is relatively harmless in comparison with reporting wrong positions. Signed-off-by:

This patch contains the following cleanups: - make the following needlessly global functions static: - dmasound_core.c: get_afmt_string() - dmasound_paula.c: dmasound_paula_init() - dmasound_q40.c: dmasound_q40_init() - remove the following unused global variable: - dmasound_core.c: software_input_volume Signed-off-by:

Attached is a revised version of my patch to add AT32 to ASoC. This cleans most of the style issues associated with the previous patch. Also fixes an issue with the playpaq_wm8510.c code depending on a non-released patch to th AT32 portmux support. Patch is against 2.6.24.3.atmel.3 kernel, the latest AVR32 kernel Atmel has released, with the linux-2.6-asoc patches from when v2.6.24 was tagged also applied.

Make the hw volume buttons work correctly on some HP OmniBook laptops. The original quirk was apparently applied a bit too early and it was also lacking some critial register writes. This improved sequence was discovered by trial and error (like the original sequence). Tested and found working on OB500 and OB6000 laptops. Signed-off-by:
