2021-04-22ASoC: adau17x1: Avoid overwriting CHPFNiklas Carlsson1-2/+11
Configuring number of channels per LRCLK frame by using e.g. snd_soc_dai_set_tdm_slot before configuring DAI format was being overwritten by the latter due to a regmap_write which would write over the whole register.

2017-09-07ASoC: adau17x1: Workaround for noise bug in ADCRicard Wanderlof1-1/+23
The ADC in the ADAU1361 (and possibly other Analog Devices codecs) exhibits a cyclic variation in the noise floor (in our test setup between -87 and -93 dB), a new value being attained within this range whenever a new capture stream is started. The cycle repeats after about 10 or 11 restarts. The workaround recommended by the manufacturer is to toggle the ADOSR bit in the Converter Control 0 register each time a new capture stream is started. I have verified that the patch fixes this problem on the ADAU1361, and according to the manufacturer toggling the bit in question in this manner will at least have no detrimental effect on other chips served by this driver.

2016-11-02ASoC: dapm: Support second register for DAPM control updatesChen-Yu Tsai1-1/+1
To support double channel shared controls split across 2 registers, one for each channel, we must be able to update both registers together. Add a second set of register fields to struct snd_soc_dapm_update, and update the DAPM control writeback (put) callbacks to support this. For codecs that use custom events which call into DAPM to do updates, also clear struct snd_soc_dapm_update before using it, so the second set of fields remains clean.

2016-06-15ASoC: adau17x1: Add support for specifying the MCLK using the CCFLars-Peter Clausen1-58/+161
The devices from the ADAU17X1 family all have a MCLK clock input which supplies the master clock for the device. The master clock is used as the input clock for the PLL. Currently the MCLK rate as well as the desired PLL output frequency need to be supplied by calling snd_soc_dai_set_pll() form a machine driver. Add support for specifying the MCLK using the common clock framework. In addition to that also automatically configure the PLL to a suitable rate if the master clock was provided using the CCW. This allows to use the CODEC driver without any special configuration requirements from the machine driver. While the PLL output frequency can be configured over a (more or less) continuous range the narrowness of the range and the other constraints of the clocking tree usually only result in two output frequencies that will actually be chosen. One for 44.1kHz based rates and one for 48kHz based rates, these are the rates that the automatic PLL configuration will use. For the rare case where a non-standard setup is required a machine driver can disable the auto-configuration and configure a custom frequency using the existing mechanisms. If the common clock framework is not enabled clk_get() will return NULL and the driver will function as before and the clock rate needs to be configured manually.

2016-06-09ASoC: adau: Factor out shared PLL configuration codeLars-Peter Clausen1-34/+4
Multiple devices from the ADAU family share the same PLL structure and configuration register layout. Introduce a new helper module that can be used to calculated the PLL configuration registers based on a specified input frequency and the desired output frequency of the PLL. The ADAU1761/ADAU1781 and ADAU1373 drivers are updated to make use of this new helper module. But future drivers for additional devices from the ADAU family are also expected to make use of it. In anticipation of sharing more infrastructure code between different devices from the ADAU family the new module is called adau-utils.

2014-11-20ASoC: sigmadsp: Restructure in preparation for fw v2 supportLars-Peter Clausen1-6/+48
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.
