Drop the snd_soc_dai_set_bclk_ratio() call, the rt5651 dai does not have a set_bclk_ratio() op, so it is a nop (and returns -EINVAL). Signed-off-by:

When platform_clock_control() first selects PLL1 as sysclk the PLL_CTRL registers have not been setup yet and we effectively have an invalid clock configuration until byt_rt5651_aif1_hw_params() gets called. Add a new byt_rt5651_prepare_and_enable_pll1() helper and use that from both platform_clock_control() and byt_rt5651_aif1_hw_params() to fix this. Tested-by:

Before this commit it was possible to set the DMIC_EN quirk in the machine driver, but it would never be passed to the codec driver so it was a nop. This commit adds code to actually pass the quirk to the codec driver. Since the DMIC_EN quirk was ignored before, this commit removes it from the default quirk settings, to avoid this causing an unexpected functional change. If we really want the DMIC_EN behavior anywhere it should be specifically enabled by follow up commits. Signed-off-by:

If we cannot find the codec ACPI-dev, then the snd-soc-core will not be able to find the codec either and snd_soc_register_card() will just keep exiting with -EPROBE_DEFER, filling the log with errors each time the probe gets retried. Instead simply log an error from the machine driver and exit with -ENODEV. Signed-off-by:

We get the insertion event before the jack is fully inserted at which point the second ring on a TRRS connector may short the 2nd ring and sleeve contacts. Testing has shown that this short-circuit may happen as late as 500ms after the insertion event, but it never lasts longer then 300ms. This commit changes the detection algorithm to require 5 identical OVCD values in a row at 100 ms intervals to fix the jack-type sometimes getting mis-detected. Tested-by:

Hans de Goede authored
When using RCCLK instead of MCLK / PLL1 the OVCD status often gets stuck at its last value, which breaks jack-type detection. This commit fixes this by force-enabling the platform clock when doing jack-type detection. Tested-by:

When the mic-gnd contacts are short-circuited by a headphones plug, the hardware periodically retries if it can apply the bias-current leading to the OVCD status flip-flopping 1-0-1 with it being 0 about 10% of the time. This commit enables the sticky bit for the OVCD status to deal with this. This commit also introduces 2 helper functions to deal with the OVCD status bit, this may seem a bit overkill now, but these will also be used in future patches. Tested-by:

OVer-Current-Detection (OVCD) for the micbias current is used to detect if an inserted jack is a headset or headphones (mic shorted to ground). The threshold for at which current the OVCD triggers on the rt5651 is not only controlled by setting the absolute current limit, but also by setting a scale factor which applies to the limit. Testing has shown that we need to set both (depending on the board). This commit adds support for the sofar unused OVCD scale-factor register and adds support for specifying non-default values for it through the "realtek,over-current-scale-factor" device-property.

OVer-Current-Detection (OVCD) for the micbias current is used to detect if an inserted jack is a headset or headphones (mic shorted to ground). Some boards may need different values for the OVCD current threshold because of a resistor on the board in serial with or parallel to the jack mic contact. This commit adds support for configuring the OCVD current threshold through the "realtek,over-current-threshold-microamp" device-property. Note this commit changes the default value from 600uA to 2000uA, because testing has shown 600uA to be a poor default. Signed-off-by:

The idea behind exporting rt5651_apply_properties(), was for it to be used on platforms where the platform code may need to add device-properties, rather then relying only on properties set by the firmware. The platform code could then call rt5651_apply_properties() after adding properties to make sure that the codec driver was aware of the new properties. But this is not necessary, as long as we do all property parsing from the codec component-driver's probe function (or later) then the machine driver can attach properties before calling snd_soc_register_card and calling rt5651_apply_properties() for ordering reasons is not necessary. This commit makes rt5651_apply_properties() private and adds 2 comments documenting that all property parsing must be done from the codec component-driver's probe function. Signed-off-by:

Currently DMIC capture and WoV usecase uses same BE DAI but operate at different sampling rates, this results in config mismatch for WoV when DMIC is already running in parallel. DMIC has two slots which can operate with some constraints, so add BE DAI for DMICvoice pin which can used for WoV usecases to capture 4ch, 16KHz, 16bit data. Signed-off-by:

To determine if a plugged in jack is a headset (speakers + mic) or headphones (mic contact shorted to ground) we use the micbias1 OVer Current Detect (OVCD) functionality. For this to work we need to have a micbias current to actually cause an overcurrent condition when headphones are plugged in, so jack-type detection requires both the LDO and micbias1 supplies to be on. Before this commit there were 2 issues with the handling of this: 1) The LDO supply was force-enabled twice and never disabled again even though it only needs to be forced on when doing jack-type detection 2) micbias1 was not force-enabled, and thus may be off when doing jack-type detection This commit fixes both by force-enabling the LDO and micbias1 supplies before checking for an overcurrent condition and disabling them afterwards. Note that both supplies will still get turned on normally (and OVCD will protect against overcurrent) when the micbias1 is enabled normally because the user has activated a sound stream recording from the mic.

Remove the "JD power" dapm supply which gets force-enabled once when using jack-detect and never gets disabled again. Since the PWR_JD_M bit simply needs to be always on when using jack-detect there is no need to have it tracked by dapm, instead we can simply set it to 1 once when initializing the jack-detection.

Remove the setup of the PWR_ANLG1 reg which was done directly before calling snd_soc_component_force_bias_level(SND_SOC_BIAS_OFF), as the latter will override any settings done to PWR_ANLG1 immediately anyways. Tested-by:

Hans de Goede authored
rt5651_set_bias_level(BIAS_OFF) used to unconditionally clear the entire register, including the jack-detect and PLL power bits. When jack-detection support was introduced a special case for jack-detect was added which hard-codes a register value to keep both on. This commit removes the jack-detect special case, instead simply leaving these bits as is on BIAS_OFF. Tested-by:

The PWR_ANLG1 reg not only contains various power on/off bits, it also contains 2 bits which select if the LDO generates 1.0, 1.1 or 1.2V. Note there is a separate on/off bit for the LDO. rt5651_set_bias_level(BIAS_OFF) used to unconditionally clear the entire register, when jack-detection support was introduced a special case for jack-detect was added which hard-codes a register value to keep the LDO voltage at 1.2 volt. This commit removes the jack-detect special case, instead simply always leaving the LDO voltage control bits as is on BIAS_OFF. Tested-by:

The rt5651_set_bias_level() function was turning everything off at SND_SOC_BIAS_STANDBY, rather then at SND_SOC_BIAS_OFF, requiring the bias- level to be raised to SND_SOC_BIAS_PREPARE before turning anything on. This is not how the bias-levels are supposed to work, this commit fixes this by turning everything off at the SND_SOC_BIAS_OFF level and enabling the pwr-bits needed for minimum functionality at SND_SOC_BIAS_STANDBY. This fixes the minimum set of pwr-bits not getting enabled when force-enabling some dapm-supplies (e.g. for jack type detection), which raises the bias-level to standby. Signed-off-by:

is_sys_clk_from_pll() is used as a snd_soc_dapm_route.connected callback, checking RT5651_GBL_CLK to determine if the sys-clk is PLL1 and thus the PWR_PLL bit in reg PWR_ANLG2 must be set. RT5651_GBL_CLK is changed by rt5651_set_dai_sysclk(), which gets called by the pre_pmu / post_pmd functions of the "Platform Clock" dapm-supply. This creates an ordering issue, during a dapm transition first all connected() callbacks are called to build a list of supplies to enable and then the complete list is walked to enable the supplies. Since the connected() check happens before enabling any supplies, is_sys_clk_from_pll() ends up deciding if the PWR_PLL bit should be set based on the state the "Platform Clock" supply had *before* the transition. This sometimes results in PWR_PLL being off, even though *after* the transition PLL1 is configured as sys-clk. This commit removes is_sys_clk_from_pll() instead simply setting / clearing PWR_PLL in rt5651_set_dai_sysclk() based on the selected sys-clk, which fixes this and as a bonus results in a nice cleanup.

Move the applying of the differential input and dmic properties to a new rt5651_apply_properties() helper function. This new function can be called by platform code which attaches properties after probe() has run to apply these new properties. Note this also moves the time when we apply these properties for DT platforms from i2c-probe to snd-component-probe time, this should not result in any functional difference. Signed-off-by:

Move 2 functions higher up in rt5651.c, this is a preparation patch to avoid needing forward declarations when moving over from a codec private function to the standard snd_soc_component_set_jack(). This commit purely moves these 2 functions up, not a single line is changed. Signed-off-by:

Move all jack-detect initialization to rt5651_set_jack_detect. The main reason to do this is so that platform code can setup jack-detect properties after the device has been probed, which unfortunately is necessary on some platforms. This has 2 additional advantages: 1) Grouping all jack-detect init together makes it easier to follow what is happening and results in a small reduction in the number of loc. 2) Before we would register the irq handler before rt5651->hp_jack was assigned, leading to a potential NULL deref if the jack_detect work runs before the machine driver has called set_jack.
