2021-10-25ASoC: cs42l42: Prevent NULL pointer deref in interrupt handlerRichard Fitzgerald1-1/+1
The interrupt handling code was getting the struct device* from a struct snd_soc_component* stored in struct cs42l42_private. If the interrupt was asserted before ASoC calls component_probe() the snd_soc_component* will be NULL. The stored snd_soc_component* is not actually used for anything other than indirectly getting the struct device*. Remove it, and store the struct device* in struct cs42l42_private.

2021-10-15ASoC: cs42l42: Set correct SRC MCLKRichard Fitzgerald1-0/+1
According to the datasheet the SRC MCLK must be as near as possible to (125 * sample rate). This means it should be ~6MHz for rates up to 48k and ~12MHz for rates above that. As per datasheet table 4-21.

2021-10-15ASoC: cs42l42: Allow time for HP/ADC to power-up after enableRichard Fitzgerald1-0/+2
After enabling the HP or ADC by writing the corresponding PDN=0, it takes around 20 milliseconds for it to power up and the midrail supply to be stable. Add this wait into a DAPM widget callback. If HP and ADC are both powering up in a DAPM sequence, there's no need to do the wait twice. The widget will perform one wait in the POST_PMU if there was a PRE_PMU for one or both.

2021-09-27ASoC: cs42l42: Use two thresholds and increased wait time for manual type detectionStefan Binding1-0/+5
Some headsets require very different comparator thresholds for type detection, as well as longer settling times. In order to detect a larger number of headsets, use 2 thresholds to give maximum coverage (1.25V and 1.75V), as well as a longer settling time of 100ms. This will not affect default audotodetect mode and applies to manual mode type detection only.

ASoC: Fixes for v5.14 Quite a lot of fixes here, the biggest set being for the cs42l42 driver which is reasonably old but has seen a sudden uptick in activity. There's also some fixes for correctly referencing PCM buffer addresses and the removal of some driver-local bodges that had been done for the lack of prefix handling in DAPM which were broken by the core handling that as expected.

2021-08-05ASoC: cs42l42: Fix mono playbackRichard Fitzgerald1-0/+2
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: PLL must be running when changing MCLK_SRC_SELRichard Fitzgerald1-0/+1
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.

HSBIAS_SENSE_EN configures HSBIAS output current sense through the external 2.21-k resistor. HSBIAS_SENSE is hardware feature to reduce the potential pop noise during the headset plug out slowly. But on some platforms ESD voltage will affect it causing test to fail, especially with CTIA headset type. For different hardware setups, a designer might want to tweak default behavior.
