* ASoC: tlv320aic32x4: Add Playback PowerTune ControlsAnnaliese McDermond2019-04-041-0/+2
| | | | | | | | | | | PowerTune controls the power level of the chip. On playback this indirectly controls things like the gain of the various output amplifiers. This can allow for the decrease of output levels from the codec. This adds controls for those power levels to the driver.

* ASoC: tlv320aic32x4: Dynamically Determine ClockingAnnaliese McDermond2019-03-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | The existing code uses a static lookup table to determine the settings of the various clock devices on board the chip. This is limiting in a couple of ways. First, this doesn't allow for any master clock rates other than the three that have been precalculated. Additionally, new sample rates are difficult to add to the table. Witness that the chip is capable of 192000 Hz sampling, but it is not provided by this driver. Last, if the driver is clocked by something that isn't a crystal, the upstream clock may not be able to achieve exactly the rate requested in the driver. This will mean that clocking will be slightly off for the sampling clock or that it won't work at all. This patch determines the settings for all of the clocks at runtime considering the real conditions of the clocks in the system. The rules for the clocks are in TI's SLAA557 application guide on pages 37, 51 and 77. Signed-off-by: Annaliese McDermond <nh6z@nh6z.net> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: tlv320aic32x4: Model DAC/ADC dividers in CCFAnnaliese McDermond2019-03-251-0/+4
| | | | | | | | | | | | Model and manage DAC/ADC dividers as components in the Core Clock Framework. This should allow us to do some more complex clock management and power control. Also, some of the on-board chip clocks can be exposed to the outside, and this change will make those clocks easier to consume by other parts of the kernel.

* ASoC: tlv320aic32x4: SND_SOC_DAPM_MICBIAS is deprecatedb-ak2019-01-091-0/+1
| | | | | | | | | | | | SND_SOC_DAPM_MICBIAS is deprecated, replace it with SND_SOC_DAPM_SUPPLY. MICBIAS voltage wasn't supplied to the microphone with the older SND_SOC_DAPM_MICBIAS widget, hence the microphone wouldn't work. This patch fixes the problem.

* ASoC: tlv320aic32x4: Use snd_soc_update_bits() in aic32x4_hw_params()Andrew F. Davis2017-12-131-0/+8
| | | | | | | | | | | Make the code easier to read by using snd_soc_update_bits() over read/modify/write sequences. Also use separate per-register variables instead of re-using "data". This can prevent accidental over-writing and makes it clear for which register each bit value is intended. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: tlv320aic32x4: Use BIT and GENMASK for bit field definitionsAndrew F. Davis2017-12-131-45/+87
| | | | | | | | | | Inter-register definitions should use BIT and GENMASK definitions and also be grouped by what register they belong to. This makes it easy to cross-check with the datasheet and is consistent with other drivers. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: tlv320aic32x4: Drop define mapping from number to numberAndrew F. Davis2017-12-131-4/+0Star
| | | | | | | | | Drop definition of frequencies that only map from one number to the same number. This is not needed and if misused can hide bugs. Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: tlv320aic32x4: Use AIC32X4_REG macro for all register definitionsAndrew F. Davis2017-12-131-75/+77
| | | | | | | | | All register definitions should use the AIC32X4_REG macro, even the ones in page 0. This makes datasheet lookup more consistent and helps with alignment both in this file and across other tlv320aic* drivers. Signed-off-by: Andrew F.

* ASoC: tlv320aic32x4: Add gpio configuration to the codecDan Murphy2017-07-171-0/+3
| | | | | | | | | | | | Add the ability to configure the MFP1->MFP5 registers as GPIOs. In addition adding ALSA controls to get and set the GPIO state. Per the data sheet each MFP can be configured as a GPIO input only, output only or either an input or output. Signed-off-by: Dan Murphy <dmurphy@ti.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: tlv320aic32x4: Break out I2C support into separate moduleJeremy McDermond2016-04-191-0/+7
| | | | | | | | | | To prepare for abstracting adding SPI support, the I2C pieces needs to be in its own moudle. This patch moves common probe code into aic32x4_probe and common removal code into aic32x4_remove. It also creates a static regmap config structure to be copied in the I2C specific driver.

* ASoC: tlv320aic32x4: Fix MICPGA input configurationMarkus Pargmann2014-01-271-0/+2
| | | | | | | | | | | | | | Currently the Negative Terminal Input Routing Configuration is only set when there is a special routing configuration. If we don't use one of the inputs IN1 or IN2 as negative terminal input, the PGA and recording does not work. This patch adds a route from CM1L/CM1R to the PGA as negative input by default. With this configuration the PGA can amplify all input signals and line-in/mic works again. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: tlv320aic32x4: Fix mono playbackMarkus Pargmann2014-01-271-0/+1
| | | | | | | | | | | | Playback of a mono stream should output the same stream on both channels. At the moment only the left analog signal is valid, the right one is just noise. This patch maps the left digital channel onto both DACs when receiving a mono stream. Signed-off-by: Markus Pargmann <mpa@pengutronix.de> Signed-off-by: Mark Brown <broonie@linaro.org>
* ASoC: tlv320aic32x4: Fix problem with first capture.Javier Martin2012-11-011-0/+3
| | | | | | | | | | | | | | | | In its previous status, the first capture didn't work properly; nothing was actually recorded from the microphone. This behaviour was observed using a Visstrim M10 board. In order to solve this BUG a workaround has been added that, during the initialization process of the codec, powers on and off the ADC. The issue seems related to a HW BUG or some behavior that is not documented in the datasheet.
