2017-09-20ASoC: tas571x: Kill BUG_ON() usageTakashi Iwai1-1/+2
Don't use BUG_ON() for a non-critical sanity check on production systems. This patch replaces with a softer WARN_ON() and an error path. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-10-04ASoC: tas571x: remove improper PDN signal usage in set_bias_levelPetr Kulhavy1-14/+0
The set_bias_level toggles the PDN signal when entering SND_SOC_BIAS_STANDBY and SND_SOC_BIAS_OFF. However this has no effect and actually breaks things down (tested with TAS5717) due to the following reasons: 1) holding down PDN does not save power but holding down RST does 2) now hard mute via register 0x5 is implemented and therefore it is no longer needed to toggle PDN to enter all channel shut down 3) in order to leave PDN it is required to toggle the RST signal (see TAS5721 datasheet), which was not implemented 4) toggling PDN as implemented actually mutes PWMs and there is no audio output (tested on TAS5717) For these reasons remove the PDN signal toggling and just initialize it to inactive in probe().

2016-10-04ASoC: tas571x: extend the t_i2c time to comply with TAS5721Petr Kulhavy1-1/+1
TAS5721 datasheet recommends to wait at least 13.5ms after deasserting the RESET signal. For TAS5717 this time is only 12ms, which was the original value in the code. Extend the wait time after deasserting RESET from 12 to 13.5ms to comply with the TAS5721 specification. Signed-off-by: Petr Kulhavy <brain@jikos.cz> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-10-04ASoC: tas571x: move mixer volume controls from TAS5711 to TAS5717Petr Kulhavy1-10/+10
Channel 1 and 2 Mixer Volume controls (registers 0x72/0x73 and 0x76/0x77) were wrongly assigned to tas5711_controls in commit f252d2346022 ("ASoC: tas571x: add input channel mixer for TAS5717/19") Therefore move them to tas5717_controls.

2016-10-04ASoC: tas571x: wait 50ms after oscillator trimPetr Kulhavy1-0/+1

2016-08-08ASoC: codec duplicated callback function goes to component on tas571xKuninori Morimoto1-6/+8
codec driver and component driver has duplicated callback functions, and codec side functions are just copied to component side when register timing. This was quick-hack, but no longer needed. This patch moves these functions from codec driver to component driver. Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@renesas.com> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-06-01ASoC: tas571x: add input channel mixer for TAS5717/19Petr Kulhavy1-0/+18
Add channel 1 and 2 input mixer registers and the related ALSA mixer controls for TAS5717/19 chips. The mixer control coefficients on the chip are linear in the range -3.99999 to +3.99999, encoded in 3.23 number format. In this patch the mixer controls are limited to 128 values from 0.0 to 1.0 in 1/64 steps. Signed-off-by: Petr Kulhavy <brain@jikos.cz> Signed-off-by: Mark Brown <broonie@kernel.org>
2016-05-30ASoC: tas571x: add biquads for TAS5717/19Petr Kulhavy1-0/+170
TAS571x features multiple biquad filters. Their coefficients are stored in 20-byte registers, which cannot be supported by regmap. This patch adds read and write functions for multi-word (32-bit) register access and mixer controls for the biquads. The multi-word read/write functions can be used in the future to implement other features like DRC or output mixer.

2016-03-31ASoC: tas571x: added missing register literalsPetr Kulhavy1-0/+28
The list of TAS571x registers was incomplete. Added the missing register definitions up to the register 0x25. Added volatile and read-only register tables into tas5711_regmap_config and tas5717_regmap_config. The chip has 256 registers in total. But from address 0x29 on (0x26 to 0x28 are reserved) the register width varies between 20, 12 and 8 bytes, which the register map cannot represent.

2016-03-30ASoC: tas571x: chip type detection via I2C namePetr Kulhavy1-8/+7
The chip selection was relying only on DT. It was not possible to use the driver without DT. This adds the chip type detection from the I2C name, which allows to use the driver from the platform driver without DT.

2016-03-29ASoC: tas571x: implemented digital mutePetr Kulhavy1-4/+18
The driver did not have a mute function. The amplifier was brought out of shutdown mode (hard-mute) once for ever in probe(), which was causing clicks and pops when altering the I2C register configuration later. This adds the digital_mute() function. The amplifier unmute in probe() was removed. Signed-off-by: Petr Kulhavy <petr@barix.com> Signed-off-by: Mark Brown <broonie@kernel.org>
