Merge series "Do not handle MCLK device clock in simple-card-utils" from Sameer Pujar <spujar@nvidia.com>: With commit 1e30f642 ("ASoC: simple-card-utils: Fix device module clock") simple-card-utils can control MCLK clock for rate updates or enable/disable. But this is breaking some platforms where it is expected that codec drivers would actually handle the MCLK clock. One such example is following platform. - "arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts" In above case codec, wm8904, is using internal PLL and configures sysclk based on fixed MCLK input. In such cases it is expected that, required PLL output or sysclk, is just passed via set_sysclk() callback and card driver need not actually update MCLK rate. Instead, codec can take ownership of this clock and do the necessary configuration. So the original commit is reverted and codec driver for rt5659 is updated to fix my board which has this codec.

This reverts commit 1e30f642 ("ASoC: simple-card-utils: Fix device module clock"). The original patch ended up breaking following platform, which depends on set_sysclk() to configure internal PLL on wm8904 codec and expects simple-card-utils to not update the MCLK rate. - "arch/arm64/boot/dts/freescale/fsl-ls1028a-kontron-sl28-var3-ads2.dts" It would be best if codec takes care of setting MCLK clock via DAI set_sysclk() callback.

Many systems do not use ACPI and hence do not provide a DMI table. On non-ACPI systems a warning, such as the following, is printed on boot. WARNING KERN tegra-audio-graph-card sound: ASoC: no DMI vendor name! The variable 'dmi_available' is not exported and so currently cannot be used by kernel modules without adding an accessor. However, it is possible to use the function is_acpi_device_node() to determine if the sound card is an ACPI device and hence indicate if we expect a DMI table to be present. Therefore, call is_acpi_device_node() to see if we are using ACPI and only parse the DMI table if we are booting with ACPI. Signed-off-by:

Most steps in this table are steps of 3dB (300 centi-dB), so we can simplify the table. This not only reduces the amount of space it takes inside the kernel, this also makes alsa-lib's mixer code actually accept the table, where as before this change alsa-lib saw the "ADC PGA Gain" control as a control without a dB scale.

According to the SGTL5000 datasheet [1], the DAP_AVC_CTRL register has the following bit field definitions: | BITS | FIELD | RW | RESET | DEFINITION | | 15 | RSVD | RO | 0x0 | Reserved | | 14 | RSVD | RW | 0x1 | Reserved | | 13:12 | MAX_GAIN | RW | 0x1 | Max Gain of AVC in expander mode | | 11:10 | RSVD | RO | 0x0 | Reserved | | 9:8 | LBI_RESP | RW | 0x1 | Integrator Response | | 7:6 | RSVD | RO | 0x0 | Reserved | | 5 | HARD_LMT_EN | RW | 0x0 | Enable hard limiter mode | | 4:1 | RSVD | RO | 0x0 | Reserved | | 0 | EN | RW | 0x0 | Enable/Disable AVC | The original default value written to the DAP_AVC_CTRL register during sgtl5000_i2c_probe() was 0x0510. This would incorrectly write values to bits 4 and 10, which are defined as RESERVED. It would also not set bits 12 and 14 to their correct RESET values of 0x1, and instead set them to 0x0. While the DAP_AVC module is effectively disabled because the EN bit is 0, this default value is still writing invalid values to registers that are marked as read-only and RESERVED as well as not setting bits 12 and 14 to their correct default values as defined by the datasheet. The correct value that should be written to the DAP_AVC_CTRL register is 0x5100, which configures the register bits to the default values defined by the datasheet, and prevents any writes to bits defined as 'read-only'. Generally speaking, it is best practice to NOT attempt to write values to registers/bits defined as RESERVED, as it generally produces unwanted/undefined behavior, or errors. Also, all credit for this patch should go to my colleague Dan MacDonald <dmacdonald@curbellmedical.com> for finding this error in the first place.

The adc_vol_tlv volume-control has a range from -17.625 dB to +30 dB, not -176.25 dB to + 300 dB. This wrong scale is esp. a problem in userspace apps which translate the dB scale to a linear scale. With the logarithmic dB scale being of by a factor of 10 we loose all precision in the lower area of the range when apps translate things to a linear scale. E.g. the 0 dB default, which corresponds with a value of 47 of the 0 - 127 range for the control, would be shown as 0/100 in alsa-mixer. Since the centi-dB values used in the TLV struct cannot represent the 0.375 dB step size used by these controls, change the TLV definition for them to specify a min and max value instead of min + stepsize. Note this mirrors commit 3f31f7d9 ("ASoC: rt5670: Fix dac- and adc- vol-tlv values being off by a factor of 10") which made the exact same change to the rt5670 codec driver. Signed-off-by:

When I added the quirk for the "HP Pavilion x2 10-p0XX" I copied the byt_rt5640_quirk_table[] entry for the HP Pavilion x2 10-k0XX / 10-n0XX models since these use almost the same settings. While doing this I accidentally also copied and kept the non-standard OVCD_TH_1500UA setting used on those models. This too low threshold is causing headsets to often be seen as headphones (without a headset-mic) and when correctly identified it is causing ghost play/pause button-presses to get detected.

For reliable output-mute LED control we need a "DAC1 Playback Switch" control. The "DAC Playback volume" control is the only control in the path from the DAC1 data input to the speaker output, so the UCM profile for the speaker output will have its PlaybackMixerElem set to "DAC1". But userspace (pulseaudio) will set the "DAC1 Playback Volume" control to its softest setting (which is not fully muted) while still showing the speaker as being enabled at a low volume in the UI. If we were to set the SNDRV_CTL_ELEM_ACCESS_SPK_LED on the "DAC1 Playback Volume" control, this would mean then what pressing KEY_VOLUMEDOWN the speaker-mute LED (embedded in the volume-mute toggle key) would light while the UI is still showing the speaker as being enabled at a low volume, meaning that the UI and the LED are out of sync. Only after an _extra_ KEY_VOLUMEDOWN press would the UI show the speaker as being muted. The path from DAC1 data input to the speaker output does have a digital mixer with DAC1's data as one of its inputs direclty after the "DAC1 Playback Volume" control. This commit adds an emulated "DAC1 Playback Switch" control by: 1. Declaring the enable flag for that mixers DAC1 input as well as the "DAC1 Playback Switch" control both as SND_SOC_NOPM controls. 2. Storing the settings of both controls as driver-private data 3. Only clearing the mute flag for the DAC1 input of that mixer if the stored values indicate both controls are enabled. This is a preparation patch for adding "audio-mute" LED trigger support. Signed-off-by:

The SND_SOC_DAPM_MIXER declaration for "Sto1 ADC MIXL" and "Sto1 ADC MIXR" was using the mute bits from the RT5670_STO1_ADC_DIG_VOL control as mixer master mute bits. But these bits are already exposed to userspace as controls as part of the "ADC Capture Volume" / "ADC Capture Switch" control pair: SOC_DOUBLE("ADC Capture Switch", RT5670_STO1_ADC_DIG_VOL, RT5670_L_MUTE_SFT, RT5670_R_MUTE_SFT, 1, 1), SOC_DOUBLE_TLV("ADC Capture Volume", RT5670_STO1_ADC_DIG_VOL, RT5670_L_VOL_SFT, RT5670_R_VOL_SFT, 127, 0, adc_vol_tlv), Both the fact that the mute bits belong to the same reg as the vol-ctrl and the "Digital Mixer Path" diagram in the datasheet clearly shows that these mute bits are not part of the mixer and having 2 separate controls poking at the same bits is a bad idea. Remove the master-mute bits settings from the "Sto1 ADC MIXL" and "Sto1 ADC MIXR" DAPM widget declarations, avoiding these bits getting poked from 2 different places. This should not cause any issues for userspace. AFAICT the rt567x codecs are only used on x86/ACPI devices and the UCM profiles used there already set the "ADC Capture Switch" as needed.

The "OUT Channel Switch" control is a left over from code copied from thr rt5640 codec driver. With the rt5640 codec driver the output volume controls have 2 pairs of mute bits: bit 7, 15: Mute Control for Spk/Headphone/Line Output Port bit 6, 14: Mute Control for Spk/Headphone/Line Volume Channel Bits 7 and 15 are normal mute bits on the rt5670/5672 which are controlled by 2 dapm widgets: SND_SOC_DAPM_SWITCH("LOUT L Playback", SND_SOC_NOPM, 0, 0, &lout_l_enable_control), SND_SOC_DAPM_SWITCH("LOUT R Playback", SND_SOC_NOPM, 0, 0, &lout_r_enable_control), But on the 5670/5672 bit 6 is always reserved, where as bit 14 is "LOUT Differential Mode" on the 5670 and also reserved on the 5672. So the "OUT Channel Switch" control which is controlling bits 6+14 of the "LINE Output Control" register is bogus -> remove it. This should not cause any issues for userspace. AFAICT the rt567x codecs are only used on x86/ACPI devices and the UCM profiles used there do not use the "OUT Channel Switch" control. Signed-off-by: -
