Reset (aka power off) happens when the reset gpio is made active.

2020-09-17ASoC: ak4458: Add DSD support for ak4458 and ak4497Shengjiu Wang1-7/+82
Ak4458 can't support DSD512 format, but ak4497 can, so add a new enum variable (enum ak4458_type) in ak4458_drvdata to distinguish these two platforms. Ak4497 has two kinds of DSD input pin, it can be selected by the dsd-path property from DT. In hw_params(), bit clock is calculated according to different DSD format (DSD64, DSD128, DSD256, DSD512), then registers are configured.

2020-08-18ASoC: ak4458: Add regulator supportShengjiu Wang1-1/+30
"AVDD" is for analog power supply, "DVDD" is for digital power supply, they can improve the power management. As the regulator is enabled in pm runtime resume, which is behind the component driver probe, so accessing registers in component driver probe will fail. Fix this issue by enabling regcache_cache_only after pm_runtime_enable.

2020-07-17ASoC: codecs: ak*: merge .digital_mute() into .mute_stream()Kuninori Morimoto1-2/+3
snd_soc_dai_digital_mute() is internally using both mute_stream() (1) or digital_mute() (2), but the difference between these 2 are only handling direction. We can merge digital_mute() into mute_stream int snd_soc_dai_digital_mute(xxx, int direction) { ... else if (dai->driver->ops->mute_stream) (1) return dai->driver->ops->mute_stream(xxx, direction); else if (direction == SNDRV_PCM_STREAM_PLAYBACK && dai->driver->ops->digital_mute) (2) return dai->driver->ops->digital_mute(xxx); ... } Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Reviewed-by: Peter Ujfalusi <peter.ujfalusi@ti.com> Link: https://lore.kernel.org/r/87pn95wiwa.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>

2019-01-07ASoC: ak4458: Add support for AK4497Daniel Baluta1-3/+76
AK4497 is a 32-bit 2ch DAC and has the same register map as AK4458 with few exceptions: * AK4497 has one more register at the end of register space DFS_READ which is a read only register that allows users to read FS Auto Detection mode. We currently do not use this register so we use the same regmap structure as for ak4458. * Because AK4458 is an 8ch DAC there are some fields that are only used by AK4458 and marked as reserved for AK4497, so for this reason we need to have a distinct set of controls, widgets and routes.
