ASoC: sta32x: Write the register default value to cache for reserved registers

2011-10-13T10:50:05+00:00

Chip documentation explicitly requires that the reset values of reserved register bits are left untouched. codec->hw_read is broken now. Here we use below trick to avoid writing to reserved registers while resume. Write the register default value to cache for reserved registers, so the write to the these registers are suppressed by the cache restore code when it skips writes of default registers.

ASoC: sta32x: Move resource allocation and release to the corresponding callback functions

2011-08-18T16:25:56+00:00

This patch includes below small fixes: 1. Move sta32x_set_bias_level() from sta32x_i2c_remove() to sta32x_remove(). 2. Remove a redundant regulator_bulk_free() call in sta32x_i2c_remove(), as we will call regulator_bulk_free() in sta32x_remove(). 3. Remove unneeded snd_soc_codec_set_drvdata(codec, NULL) in sta32x_i2c_remove. The i2c core will set the clientdata to NULL.

ASoC: sta32x: shortcut the for loop to get ir and mcs

2011-08-15T13:54:11+00:00

There is exactly one match or no match at all during the for loop iteration, thus we can break from the for loop once a match is found. Signed-off-by: Axel Lin Acked-by: Johannes Stezenbach Signed-off-by: Mark Brown

ASoC: STA32x: Preserve reserved register bits

2011-07-13T15:24:32+00:00

Chip documentation explicitly requires that the reset values of reserved register bits are left untouched. It is possible there are differences between STA326 and STA328 or future chip revisions in these bits, and clobbering them might cause malfunction.

ASoC: STA32x: Add mixer controls for biquad coefficients

2011-07-13T15:24:31+00:00

The STA32x has a number of preset EQ settings, but also allows full user control of the biquad filter coeffcients (when "Automode EQ" is set to "User"). Each biquad has five signed, 24bit, fixed-point coefficients representing the range -1...1. The five biquad coefficients can be uploaded in one atomic operation into on-chip coefficient RAM. There are also a few prescale, postscale and mixing coefficients, in the same numeric format and range (a negative coefficient inverts phase). These coefficients are made available as SNDRV_CTL_ELEM_TYPE_BYTES mixer controls. Signed-off-by: Johannes Stezenbach Signed-off-by: Mark Brown
