2018-12-07ASoC: max9867: Add copyright and module authorLadislav Michl
Driver rewritten, assign copyright notice and change module author as original one remains silent and I want to be notified about bugs. Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Mark Brown <broonie@kernel.org>
2018-12-07ASoC: max9867: Fix signal pathsLadislav Michl
Sound capture and line bypass currently do not work as well as some mixer controls. Fix that by building proper audio paths and adjusting volume controls to match datasheet. Signed-off-by: Ladislav Michl <ladis@linux-mips.org> Signed-off-by: Mark Brown <broonie@kernel.org>

2017-08-18ASoC: codecs: constify snd_soc_dai_ops structuresArvind Yadav
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>
2017-08-10ASoC: codecs: add const to snd_soc_codec_driver structuresBhumika Goyal
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.

2017-04-05ASoC: max9867: export OF device ID as module aliasesJavier Martinez Canillas
The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it. While there, move the MODULE_DEVICE_TABLE(i2c, max9867_i2c_id) just next to the I2C device table declaration, for consistency with other drivers.

TLV_DB_RANGE_HEAD macro was obsoleted by commit bf1d1c9b6179 ("ALSA: tlv: add DECLARE_TLV_DB_RANGE()").

2016-08-08ASoC: codec duplicated callback function goes to component on wm9867Kuninori Morimoto
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.
