2021-09-16Merge series "ASoC: cs42l42: Implement Manual Type detection as fallback" ↵Mark Brown
from Vitaly Rodionov <vitalyr@opensource.cirrus.com>: For some headsets CS42L42 autodetect mode is not working correctly. They will be detected as unknown types or as headphones. According to the CS42L42 datasheet, if the headset autodetect failed, then the driver should switch to manual mode and perform a manual steps sequence. These steps were missing in the current driver code. This patch will add manual mode fallback steps in case autodetect failed. The default behavior is not affected, manual mode runs only when autodetect failed. Tested for regression with autodetect with all known headsets - no regression. Tested with all headsets customers reported as false detected: Gumdrop DropTech B1 - detected as headset OK HUAWEI AM115 - detected as headset OK UGREEN EP103 - detected as headset OK HONOR AM116 - detected as headset OK Stefan Binding (1): ASoC: cs42l42: Implement Manual Type detection as fallback sound/soc/codecs/cs42l42.c | 104 ++++++++++++++++++++++++++++++++----- sound/soc/codecs/cs42l42.h | 54 +++++++++++++++++++ 2 files changed, 146 insertions(+), 12 deletions(-) -- 2.25.1

2021-08-05ASoC: cs42l42: Assume 24-bit samples are in 32-bit slotsRichard Fitzgerald
If the machine driver doesn't call snd_soc_dai_set_sysclk() the SCLK is assumed to be sample_rate * sample_bits * 2 (that is, the rate necessary for a standard I2S frame). But 24-bit samples can be sent in either a 24-bit slot or a 32-bit slot. If the PLL is configured for a 24-bit slot, but a 32-bit slot is used, cs42l42 will be overclocked. Ultimately it is the machine driver's responsibilty to call snd_soc_dai_set_sysclk() if SLK will be different from the standard I2S rate. However, it is convenient to assume 32-bit slots to allow this common case without needing special machine driver support. The machine driver then only has to set SCLK if the slots are 24-bit, but if it fails to do this cs42l42 won't be overclocked.

2021-08-05ASoC: cs42l42: Fix mono playbackRichard Fitzgerald
I2S always has two LRCLK phases and both CH1 and CH2 of the RX must be enabled (corresponding to the low and high phases of LRCLK.) The selection of the valid data channels is done by setting the DAC CHA_SEL and CHB_SEL. CHA_SEL is always the first (left) channel, CHB_SEL depends on the number of active channels. Previously for mono ASP CH2 was not enabled, the result was playing mono data would not produce any audio output.

2021-08-05ASoC: cs42l42: Constrain sample rate to prevent illegal SCLKRichard Fitzgerald
The lowest valid SCLK corresponds to 44.1 kHz at 16-bit. Sample rates less than this would produce SCLK below the minimum when using a normal I2S frame. A constraint must be applied to prevent this. The constraint is not applied if the machine driver sets SCLK, to allow setups where the host generates additional bits per LRCLK phase to increase the SCLK frequency. In these cases the machine driver would always have to inform this driver of the actual SCLK, and it must select a legal SCLK.

2021-08-05ASoC: cs42l42: PLL must be running when changing MCLK_SRC_SELRichard Fitzgerald
Both SCLK and PLL clocks must be running to drive the glitch-free mux behind MCLK_SRC_SEL and complete the switchover. This patch moves the writing of MCLK_SRC_SEL to when the PLL is started and stopped, so that it only transitions while the PLL is running. The unconditional write MCLK_SRC_SEL=0 in cs42l42_mute_stream() is safe because if the PLL is not running MCLK_SRC_SEL is already 0.

2021-08-03ASoC: cs42l42: Remove duplicate control for WNF filter frequencyRichard Fitzgerald
The driver was defining two ALSA controls that both change the same register field for the wind noise filter corner frequency. The filter response has two corners, at different frequencies, and the duplicate controls most likely were an attempt to be able to set the value using either of the frequencies. However, having two controls changing the same field can be problematic and it is unnecessary. Both frequencies are related to each other so setting one implies exactly what the other would be. Removing a control affects user-side code, but there is currently no known use of the removed control so it would be best to remove it now before it becomes a problem.

cs42l42 does not support standard burst transfers so the use_single_read and use_single_write flags must be set in the regmap config. Because of this bug, the patch: commit 0a0eb567e1d4 ("ASoC: cs42l42: Minor error paths fixups") broke cs42l42 probe() because without the use_single_* flags it causes regmap to issue a burst read. However, the missing use_single_* could cause problems anyway because the regmap cache can attempt burst transfers if these flags are not set.

2021-05-11Merge series "Tidy up device ID reading on legacy Cirrus parts" from Charles ↵Mark Brown
Keepax <ckeepax@opensource.cirrus.com>: Pierre requested I have a look at some cppcheck warnings in the cs42l42 driver, since it is reassigning the ret variable without ever checking the result. Looking a bit more broadly this happens in quite a few legacy Cirrus parts, as they all use the same process to read the ID, factor out a small helper so they can all share the same code. Whilst in there fix up a couple of other trivial error path issues as well.

2020-07-16ASoC: codecs: cs*: merge .digital_mute() into .mute_stream()Kuninori Morimoto
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/87r1tlwiwe.wl-kuninori.morimoto.gx@renesas.com Signed-off-by: Mark Brown <broonie@kernel.org>
