2011-12-02ASoC: Drop unused state parameter from CODEC suspend callbackLars-Peter Clausen1-1/+1
The existence of this parameter is purely historical. None of the CODEC drivers uses it and we always pass in the same value anyway, so it should be safe to remove it.

2011-11-23ASoC: Constify snd_soc_dai_ops structsLars-Peter Clausen1-3/+3
Commit 1ee46ebd("ASoC: Make the DAI ops constant in the DAI structure") introduced the possibility to have constant DAI ops structures, yet this is barley used in both existing drivers and also new drivers being submitted, although none of them modifies its DAI ops structure. The later is not surprising since existing drivers are often used as templates for new drivers. So this patch just constifies all existing snd_soc_dai_ops structs to eliminate the issue altogether. The patch was generated with the following coccinelle semantic patch: // <smpl> @@ identifier ops; @@ -struct snd_soc_dai_ops ops = +const struct snd_soc_dai_ops ops = { ... }; // </smpl> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com>
2011-10-22ASoC: max98095: Convert codec->hw_write to snd_soc_writeAxel Lin1-7/+6
codec->hw_write is broken now, convert codec->hw_write to snd_soc_write. The hardware has 2 banks of registers sharing a section in I2C register space. The 1st bank is the primary one and is cached. The 2nd bank is for loading coefficients only and they do not need cache. These coefficients registers are therefore direct writes. Thus we set cache_bypass flag to deal with this before calling snd_soc_write.

2011-10-04ASoC: max98095 codec: Catch driver bugs for biquad channel nameRyan Mallon1-10/+22
Move the biquad channel names to a separate array and iterate over it in max98095_get_bq_channel rather than duplicating the hardcoded channel names. Add an error message if an invalid channel is passed and check the error in the callers. Also added a BUILD_BUG_ON to ensure that the bq_mode_name and controls arrays are the same size.

2011-09-28ASoC: Remove unused "control_data" field of struct max98095_privAxel Lin1-2/+0
The control_data field is used to initialize the codec's control_data field, but since this is also done by the snd-soc-cache core, the redundant assignment can be removed and the field can be dropped.

2011-06-22ASoC: codecs: Max98095: Fix logging of hardware revision.Taylor Hutt1-4/+4
The base hardware revision of the Maxim 98095 part is 0x40; the code which outputs the revision of the hardware has been updated to properly use uppercase alphabetic values for the revision numbers. Also, the use of a constant for the length 'max98095_dai' has been replaced with ARRAY_SIZE().

2011-05-28ASoC: Remove redundant freq assignment for max98095->sysclk/max98088->sysclkAxel Lin1-2/+0
Current implementation set max98095->sysclk/max98088->sysclk to freq twice. Set it once is enough, this patch removes the first assignment in case we may set invalid clock frequency to max98095->sysclk/max98088->sysclk.

2011-05-18ASoC: Max98095: Move existing NULL check before pointer dereference.Taylor Hutt1-10/+6
Visual inspection shows that max98095_put_eq_enum() and max98095_put_bq_enum() each have a possible NULL deref of 'pdata'. This change moves the NULL check above the use.
