2017-08-10ASoC: codecs: add const to snd_soc_codec_driver structuresBhumika Goyal1-1/+1
Declare snd_soc_codec_driver structures as const as they are only passed as an argument to the function snd_soc_register_codec. This argument is of type const, so declare the structures with this property as const. In file codecs/sn95031.c, snd_soc_codec_driver structure is also used in a copy operation along with getting passed to snd_soc_register_codec. So, it can be made const too.

2016-08-08ASoC: codec duplicated callback function goes to component on tas5086Kuninori 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>

2015-03-10ASoC: tas5086: Fix wrong value references for boolean kctlTakashi Iwai1-2/+2
The correct values referred by a boolean control are value.integer.value[], not value.enumerated.item[]. The former is long while the latter is int, so it's even incompatible on 64bit architectures.

2014-07-03ASoC: tas5086: add regulator consumer supportDaniel Mack1-9/+58
The TAS5086 has two power domains, DVDD and AVDD. Enable them both as long as the codec is in use. Also, switch on the power to identify the chip at device probe level, and switch it off again afterwards. The codec level will take care for power handling later.

2014-04-14ASoC: Add snd_soc_kcontrol_codec() helper functionLars-Peter Clausen1-2/+2
For CODEC controls snd_kcontrol_chip() currently returns a pointer to the CODEC that registered the control. With the upcoming consolidation of platform and CODEC controls this will change. Prepare for this by introducing the snd_soc_kcontrol_codec() helper function that will hide the implementation details of how the CODEC for a control can be obtained. This will allow us to change this easily in the future. The patch also updates all CODEC drivers to use the new helper function.

2013-10-25Merge tag 'asoc-v3.13' of ↵Takashi Iwai1-62/+109
git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-next ASoC: Updates for v3.13 - Further work on the dmaengine helpers, including support for configuring the parameters for DMA by reading the capabilities of the DMA controller which removes some guesswork and magic numbers fromm drivers. - A refresh of the documentation. - Conversions of many drivers to direct regmap API usage in order to allow the ASoC level register I/O code to be removed, this will hopefully be completed by v3.14. - Support for using async register I/O in DAPM, reducing the time taken to implement power transitions on systems that support it.

2013-06-28ASoC: tas5086: fix Mid-Z implementationDaniel Mack1-6/+9
It turns out that the TAS5086 doesn't like channel start parts to be empty, and if all channels are configured to Mid-Z, part 1 has to be used. Signed-off-by: Daniel Mack <zonque@gmail.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2013-06-25ASoC: tas5086: add support for pwm start mode configDaniel Mack1-0/+22
The TAS5086 has two alternative modes to start its PWM channels, Mid-Z and Low-Z. Which one to use depends on how the PWM power stages are connected to the TAS5086. This patch adds 6 optional boolean properties to the DT bindings of the driver which allow the user to configure each individual channel to the Mid-Z scheme, and leaves all the others to the default (Low-Z).

2013-03-08ALSA: ASoC: add codec driver for TI TAS5086Daniel Mack1-0/+601
This patch adds a driver for TI's TA5086 6-channel PWM processor. This chip has a very unusual register layout, specifically because the registers are of unequal size, and multi-byte registers require bulk writes to take effect. Regmap does not support these kind of mappings. Currently, the driver does not touch any of the registers >= 0x20, so it doesn't matter, because the register map is mapped to an 8-bit array. In case more features will be added in the future that require access to higher registers, the entire regmap H/W I/O routines have to be open-coded.
