2016-01-27ASoC: ssm4567: Reset device before regcache_sync()Lars-Peter Clausen1-0/+5
When the ssm4567 is powered up the driver calles regcache_sync() to restore the register map content. regcache_sync() assumes that the device is in its power-on reset state. Make sure that this is the case by explicitly resetting the ssm4567 register map before calling regcache_sync() otherwise we might end up with a incorrect register map which leads to undefined behaviour. One such undefined behaviour was observed when returning from system suspend while a playback stream is active, in that case the ssm4567 was kept muted after resume. Fixes: 1ee44ce03011 ("ASoC: ssm4567: Add driver for Analog Devices SSM4567 amplifier") Reported-by: Harsha Priya <harshapriya.n@intel.com> Tested-by: Fang, Yang A <yang.a.fang@intel.com> Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-08-14ASoC: ssm4567: Add sense supportLars-Peter Clausen1-0/+21
The ssm4567 has sensing circuitry that can be used to monitor the current and voltage on the speaker amplifier output has well as the VBAT input. This data can be output over the I2S interface so it can be processed by a DSP or similar. This patch adds the sense capture output stream to the CODEC DAI as well as DAPM widgets that ensure that the sensing circuitry is powered up when the capture stream is active.

2015-07-22ASoC: ssm4567: Keep TDM_BCLKS in ssm4567_set_dai_fmtBen Zhang1-1/+7
The regmap_write in ssm4567_set_dai_fmt accidentally clears the TDM_BCLKS field which was set earlier by ssm4567_set_tdm_slot. This patch fixes it by using regmap_update_bits with proper mask.

2015-05-04ASoC: ssm4567: Replace direct snd_soc_codec dapm field accessLars-Peter Clausen1-1/+1
The dapm field of the snd_soc_codec struct is eventually going to be removed, in preparation for this replace all manual access to codec->dapm.bias_level with snd_soc_codec_get_bias_level(). Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2015-04-27ASoC: Move bias level update to the coreLars-Peter Clausen1-6/+1
All drivers have the same line at the end of the set_bias_level callback to update the bias_level state. Move this update into snd_soc_dapm_force_bias_level() and remove them from the drivers. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-11-06ASoC: ssm4567: Add support for disabling the boost stageLars-Peter Clausen1-0/+7
This patch adds a switch to enable/disable boost stage of the output amplifier. Applications that know that they do not need the output amplifier boost stage can disable it to conserve a bit of power. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2014-11-06ASoC: ssm4567: Add support for setting the DAI format and TDM configurationLars-Peter Clausen1-0/+119
The SSM4567 has support for a couple of different DAI formats. In TDM mode it is also possible to select the TDM slot. This patch adds support for this by implementing the set_fmt and set_tdm_slot callbacks. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
