ASoC: mt6358: Add endianness flag in snd_soc_component_driver

2022-05-09T11:46:30Z

The endianness flag is used on the CODEC side to specify an ambivalence to endian, typically because it is lost over the hardware link. This device receives audio over an I2S DAI and as such should have endianness applied. As the core will now expand the formats to cover both endian types, remove the redundant manual specification of both.

ASoC: mediatek: mt6358: add delay after dmic clock on

2019-08-15T14:04:04Z

Most dmics produce a high level when they receive clock. The difference between power-on and memory record time is about 10ms, but the dmic needs 50ms to output normal data. This commit add 100ms delay after SoC output clock so that we can cut off the pop noise at the beginning.

ASoC: mediatek: mt6358: save output volume for mixer controls

2019-05-08T08:12:24Z

Output volume settings from mixer controls would be lost. Imagine that "Headphone Volume" has set to -10dB via amixer: - in mtk_hp_enable() - hp_store_gain() saves the volume setting -10dB from regmap_read() to ana_gain[AUDIO_ANALOG_VOLUME_HPOUTL] - headset_volume_ramp() ramps up from -10dB to -10dB - in mtk_hp_disable() - headset_volume_ramp() ramps down from -10dB to -40dB Next time in mtk_hp_enable(), hp_store_gain() would save -40dB but not -10dB. As a result, headset_volume_ramp() would ramp from -10dB to -40dB (which is mute). Signed-off-by: Tzung-Bi Shih Signed-off-by: Mark Brown

ASoC: mediatek: mt6358: initialize setting when ramping volume

2019-05-08T08:11:53Z

Mt6358 ramps up from the smallest volume (i.e. -10dB) to target dB when opening and ramps down from target dB to mute (i.e. -40dB) when closing. If target is equal to -10dB when opening, headset_volume_ramp() simply leaves current setting (which may not be -10dB) unchanged. Execute the loop at least once to initialize the setting to the starting point (i.e. from). Signed-off-by: Tzung-Bi Shih Signed-off-by: Mark Brown
