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.

2017-06-16ASoC: ak4613: add hw_constraint rule for Sampling RateKuninori Morimoto1-0/+61
Current ak4613 accepts all range of Sampling Rate, but it depends on inputed master clock. This patch adds hw constraint rule for it.

2017-06-07ASoC: ak4613: Improve counting DAI numberRyo Kodama1-1/+12
Add the startup function to count DAI instead of hw_params. This change matches the number of opened DAIs. If this change isn't applied, you may get unexpected error due to mismatching of count. Since the excution number of hw_params and shutdown may be different, the mismatching happens.

2017-05-14ASoC: ak4613: disable asymmetric audio interface formatKuninori Morimoto1-14/+4
Asymmetric audio interface formats exist in ak4613 by same register settings. Capture Playback 24bit LEFT_J 16bit RIGHT_J 24bit LEFT_J 20bit RIGHT_J 24bit LEFT_J 24bit RIGHT_J 24bit LEFT_J 24bit LEFT_J 24bit I2S 24bit I2S These asymmetric formats makes driver / behavior difficult. It is not HW limitation, but SW limitation. To makes code reading easy, this patch removes asymmetric format support.

2016-08-08ASoC: codec duplicated callback function goes to component on ak4613Kuninori 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>
2016-06-17ASoC: ak4613: Implement suspend callbackGeert Uytterhoeven1-1/+11
Add the suspend callback to accompany the existing resume operation. With the suspend/resume callbacks the regmap (regcache) state handling can follow the recommended sequence. Based on commit a2ebd58627e9aa48 ("ASoC: ak4642: Implement suspend callback") by Peter Ujfalusi <peter.ujfalusi@ti.com>.

2016-06-17ASoC: ak4613: Enable cache usage to fix crashes on resumeGeert Uytterhoeven1-0/+1
During system resume: kernel BUG at drivers/base/regmap/regcache.c:347! ... PC is at regcache_sync+0x1c/0x128 LR is at ak4613_resume+0x28/0x34 The ak4613 driver is using a regmap cache sync to restore the configuration of the chip on resume but does not actually define a register cache which means that the resume is never going to work and we trigger asserts in regmap. Fix this by enabling caching. Based on commit d3030d11961a8c10 ("ASoC: ak4642: Enable cache usage to fix crashes on resume") by Mark Brown <broonie@kernel.org>.
