* ASoC: tlv320: skip of_device_id table when !CONFIG_OFKrzysztof Kozlowski2020-11-261-0/+2
| | | | | | | | | | | | | The driver can match by multiple methods. Its of_device_id table is referenced via of_match_ptr() so it will be unused for !CONFIG_OF builds: sound/soc/codecs/tlv320aic23-i2c.c:38:34: warning: ‘tlv320aic23_of_match’ defined but not used [-Wunused-const-variable=] sound/soc/codecs/tlv320adcx140.c:1076:34: warning: ‘tlv320adcx140_of_match’ defined but not used [-Wunused-const-variable=] Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org> Link: https://lore.kernel.org/r/20201125164452.89239-32-krzk@kernel.org Signed-off-by: Mark Brown <broonie@kernel.org>

| | | | | | | | | | | Add support to configure the GPIO pin to the specific configuration. The GPIO pin can be configured as GPO, IRQ, SDOUT2, PDMCLK, MICBASE_EN, GPI, MCLK, SDIN, PDMDIN1, PDMDIN2, PDMDIN3 or PDMDIN4 and the output drive can be configured with various configuration.

* ASoC: tlv320adcx140: Add the config to configure Tx ASI outputDan Murphy2020-09-171-0/+11
| | | | | | | | | | | Add code to allow the ASI Tx output to be placed into High-z mode during unused ASI cycles. This allows for other devices that may be on the bus to drive the ASI out. By default the 320adcx140 sends 0's for unused cycles.

| * ASoC: tlv320adcx140: Fix BCLK inversion for DSP modesDan Murphy2020-09-171-21/+23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Fix the BCLK inversion for DSP modes This is how it is defined by ASoC: * BCLK: * - "normal" polarity means signal is available at rising edge of BCLK * - "inverted" polarity means signal is available at falling edge of BCLK The adcx140 defines the BCLK edge based on coding type. The PCM (DSP_A/B) should drive on rising and sample on falling edge, so from ASoC pov, it is IB_NF. But from the codec pov if it is configured in DSP mode, then the BCLK should not be inverted, defaults to the coding standard. For i2s, it is NB_NF from ASoC pov (drive on falling, sample on rising). >From the codec's pov BCLK should not invert either, as this is the default for the coding. So, inversion must take the format into account: IB_NF + DSP_A/B == the codec bclk inversion should be disabled NB_NF + DSP_A/B == the codec bclk inversion should be enabled NB_NF + I2S == the codec bclk inversion should be disabled Signed-off-by: Dan Murphy <dmurphy@ti.com> Link: https://lore.kernel.org/r/20200915190606.1744-2-dmurphy@ti.com Signed-off-by: Mark Brown <broonie@kernel.org>
| * ASoC: tlv320adcx140: Idle the device while writing registersDan Murphy2020-09-171-11/+32
| | | | | | | | | | | | | | | | | | | | | | | | It was observed that if the device was active and register writes were performed there were some unwanted behaviors particularly when writing the word length and some filter options. So when writing to the device the device should be placed in sleep mode and then exit sleep mode once the register update is complete.

| * ASoC: tlv320adcx140: Fix digital gain rangeCamel Guo2020-09-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | According to its datasheet, the digital gain should be -100 dB when CHx_DVOL is 1 and 27 dB when CHx_DVOL is 255. But with the current dig_vol_tlv, "Digital CHx Out Volume" shows 27.5 dB if CHx_DVOL is 255 and -95.5 dB if CHx_DVOL is 1. This commit fixes this bug.

| * ASoC: tlv320adcx140: Wake up codec before accessing registerCamel Guo2020-09-081-12/+12
| | | | | | | | | | | | | | | | | | | | | | | | According to its datasheet, after reset this codec goes into sleep mode. In this mode, any register accessing should be avoided except for exiting sleep mode. Hence this commit moves SLEEP_CFG access before any register accessing.

| | | | | | | | | | | | | | | | | | | | The TLV320ADCx140 parts support Dynamic Range Enhancer (DRE) as defined in Section 8.3.2 of the data sheets. The DRE achieves a complete-channel dynamic range as high as 120 dB. At a system level, the DRE scheme enables far-field, high-fidelity recording of audio signals in very quiet environments and low-distortion recording in loud environments. There are 2 enables for DRE. The first is a global setting that enables the DRE engine in the device and the other enable is per channel. If the DRE is enabled globally then either DRE or AGC can be used per each configured channel. If global DRE is disabled then even setting the DRE enable bit in the channel config register will have no effect.
