      ASoC: codecs: add const to snd_soc_codec_driver structures · a180ba45
      由 Bhumika Goyal 提交于 
      Declare snd_soc_codec_driver structures as const as they are only passed
as an argument to the function snd_soc_register_codec. This argument is
of type const, so declare the structures with this property as const.
In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in
a copy operation along with getting passed to snd_soc_register_codec.
So, it can be made const too.

      ASoC: sgtl5000: add avc support · a7295267
      由 Richard Leitner 提交于 
      The sgtl5000 features an automatic volume control block (AVC), which
reduces loud signals and amplifies low level signals for easier
listening. This patch adds support for this AVC block to the driver.

Apart from the "AVC Switch" control which enables the block following
controls for the configuration of AVC are added:
	+ AVC Threshold Volume: threshold where audio is compressed when
		the measured level is above or expanded when below
	+ AVC Max Gain Volume: maximum gain which can be applied when
		the measured audio level is below threshold
	+ AVC Hard Limiter Switch: when enabled the signal is limited to
		the programmed threshold.
	+ AVC Integrator Response: response time of the integrator

The AVC block is enabled and configured using the DAP_AVC_CTRL and
DAP_AVC_THRESHOLD registers.

Following 2 checkpatch.pl strict checks are ignored because the
indentation style is different for the struct snd_kcontrol_new
definition:
	patch:147: CHECK: Alignment should match open parenthesis
	patch:150: CHECK: Alignment should match open parenthesis

      ASoC: sgtl5000: Allow 8kHz playback in codec slave mode · 2a4cfd10
      由 Fabio Estevam 提交于 
      When trying to play a 8kHz file with codec in slave mode we get the following
error on a mx28evk:

$ aplay -Dhw:0,0 stereo_8k.wav
Playing WAVE 'stereo_8k.wav' : Signed 16 bit Little Endian, Rate 8000 Hz, Stereo
[   21.218647] sgtl5000 0-000a: PLL not supported in slave mode
[   21.224559] sgtl5000 0-000a: 128 ratio is not supported. SYS_MCLK needs to be 256, 384 or 512 * fs
[   21.233687] sgtl5000 0-000a: ASoC: can't set sgtl5000 hw params: -22
aplay: set_params:1123: Unable to install hw params:

This error happens because we are using 'sys_fs' instead of 'frame_rate' in the
valid ratio check.

Use the real'frame_rate' so that the ratio is correctly calculated and the
playback can run.

sgtl5000 codec manual states that in 'Synchronous SYS_MCLK input' mode that the
following SYS_CLK frequencies are allowed: 256*fs, 384*fs, 512*fs.

, where fs is the sampling frequency, which can be in the range of:
8, 11.025, 16, 22.5, 32, 44.1, 48, 96 kHz.

      ASoC: sgtl5000: Remove MCLK restriction · d819ce96
      由 Fabio Estevam 提交于 
      According to the sgtl5000 datasheet the MCLK frequency range restriction of
8 to 27 MHz only applies when the PLL is used - synchronous SYS_MCLK input mode.

When running the codec as slave, the master should generate MCLK in the range of
256*fs, 384*fs or 512*fs, which is called asynchronous SYS_MCLK input mode.

In asynchronous SYS_MCLK we cannot have the 8 to 27 MHz check because if we
want to play a 8KHz sample rate track, with a MCLK of 8k * 512 = 4.096MHz the
current check would return -EINVAL, which is not correct.

Remove the 8 to 27MHz frequency check, since this only applies to the
synchronous SYS_MCLK input case.

      ASoC: sgtl5000: Fix SMALL_POP bit definition · c251ea7b
      由 Fabio Estevam 提交于 
      On a mx28evk with a sgtl5000 codec we notice a loud 'click' sound  to happen
5 seconds after the end of a playback.

The SMALL_POP bit should fix this, but its definition is incorrect:
according to the sgtl5000 manual it is bit 0 of CHIP_REF_CTRL register, not
bit 1.

Fix the definition accordingly and enable the bit as intended per the code
comment.

After applying this change, no loud 'click' sound is heard after playback

      ASoC: sgtl5000: Cleanup bias level transitions · e649057a
      由 Lars-Peter Clausen 提交于 
      Set the CODEC driver's suspend_bias_off flag rather than manually going to
SND_SOC_BIAS_OFF in suspend and SND_SOC_BIAS_STANDBY in resume. This makes
the code a bit shorter and cleaner.

Since the ASoC core now takes care of setting the bias level to
SND_SOC_BIAS_OFF when removing the CODEC there is no need to do it manually
anymore either.

The manual transition to SND_SOC_BIAS_STANDBY at the end of CODEC probe()
can also be removed as the core will automatically do this after the CODEC
has been probed.
