* ASoC: es8316: Add support for inverted jack detectPaul Cercueil2019-04-011-0/+14
| | | | | | | | | | | | On some devices (Teclast X98+ II tablet, maybe others), the jack detection has been wired backwards, so when the ES8316 reports headphones being present it means they are actually not plugged. Use a quirk around this incorrect behaviour, which can be enabled through the 'everest,jack-detect-inverted' boolean device property.

* ASoC: es8316: Add DAC mono mix switch mixer controlHans de Goede2019-01-041-0/+1
| | | | | | | | | | | | | | | | | | | Export the DAC functionality to mix left + right together and then output the same (mixed) signal on both outputs. Various (x86) tablets with an ES8316 codec use a single speaker connected between the headhpone LOUT and ROUT pins, expecting the output to be in a mono differential mode. Presumably this is done to use the power of both the left and right outputs to allow the speaker to be louder. The ES8316 codec does not have a differential output mode, but we can emulate this by making both channels output the same through the mono mix switch, combined with setting the Playback Polarity control to "R Invert", which applias a 180 degrees phase inversion to the right channel.

* ASoC: es8316: Add jack-detect supportHans de Goede2019-01-041-4/+191
| | | | | | | | | | | | | | | | | | | | Adding jack-detect support may seem weird for a codec with only a single output, but it is necessary. The ES8316 appnote showing the intended usage uses a jack-receptacle which physically disconnects the speakers from the output when a jack is plugged in. But all 3 devices using the es8316 which I have (2 Cherry Trail devices and one Bay Trail CR device), use an analog mux to disconnect the speakers, driven by a GPIO. In order to enable/disable the speakers at the right time, we need jack-detect. The same goes for the microphone where we must correctly set the mux for the single ADC to either the internal or the headset microphone. All devices I have support the es8316's builtin jack-detect functionality. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>

* ASoC: codecs: constify snd_soc_dai_ops structuresArvind Yadav2017-08-181-1/+1
| | | | | | | | | snd_soc_dai_ops are not supposed to change at runtime. All functions working with snd_soc_dai_ops provided by <sound/soc-dai.h> work with const snd_soc_dai_ops. So mark the non-const structs as const. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: codecs: add const to snd_soc_codec_driver structuresBhumika Goyal2017-08-101-1/+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.

* ASoC: add es8316 codec driverDaniel Drake2017-06-131-0/+637
Add a codec driver for the Everest ES8316, based on code provided by David Yang from Everest Semi. I limited the functionality to items where the vendor code was clear, and things that can be tested on the Weibu F3C (Intel Cherry Trail). As a result the initial implementation only supports running in slave mode at single speed (up to 48kHz sample rate) using I2S. HPD is not supported.
