| | * ASoC: adau17x1: Mark DSP parameter memory as readable and preciousLars-Peter Clausen2014-11-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | To be able to read back data from the DSP parameter memory the register range needs to be marked as readable. At the same time we do not want them to e.g. appear in debugfs output so mark them as precious as well.

| | * ASoC: sigmadsp: Restructure in preparation for fw v2 supportLars-Peter Clausen2014-11-20
| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The v2 file format of the SigmaDSP takes a more declarative style compared to the imperative style of the v1 format. In addition some features that are supported with v2 require the driver to keep state around for the firmware. This requires a bit of restructuring of both the firmware loader itself and the drivers making use of the firmware loader. Instead of loading and executing the firmware in place when the DSP is configured the firmware is now loaded at driver probe time. This is required since the new firmware format will in addition to the firmware data itself contain meta information describing the firmware and its requirements and capabilities. Those will for example be used to restrict the supported samplerates advertised by the driver to userspace to the list of samplerates supported for the firmware. This only does the restructuring required by the v2 format, but does not yet add support for the new format itself.

* / ASoC: adau17x1: Replace w->codec with snd_soc_dapm_to_codec(w->dapm)Lars-Peter Clausen2014-11-17
|/ | | | | | | | The codec field of the snd_soc_widget struct is eventually going to be removed, use snd_soc_dapm_to_codec(w->dapm) instead. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: adau17x1: Cleanup manual bias level transitionsLars-Peter Clausen2014-09-04
| | | | | | | | | 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. Signed-off-by: Lars-Peter Clausen <lars@metafoo.de> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: Add ADAU1381/ADAU1781 audio CODEC supportLars-Peter Clausen2014-05-27
This patch adds support for the Analog Devices ADAU1381 and ADAU1781 audio CODECs. The device is a low-power, 24-bit stereo audio CODEC with multiple analog inputs and outputs, two digital microphone inputs and an I2S interface. The device can be controlled either using I2C or SPI. The main difference between the two variants is that the ADAU1781 has a freely programmable SigmaDSP processor, while the ADAU1381 has a fixed function wind noise reduction filter.
