* 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. Done using Coccinelle: @match disable optional_qualifier@ identifier s; position p; @@ static struct snd_soc_codec_driver s@p={...}; @good1@ identifier match.s; position p; @@ snd_soc_register_codec(...,&s@p,...) @bad@ identifier match.s; position p!={match.p,good1.p}; @@ s@p @depends on !bad disable optional_qualifier@ identifier match.s; @@ static +const struct snd_soc_codec_driver s={...}; Signed-off-by: Bhumika Goyal <bhumirks@gmail.com> Signed-off-by: Mark Brown <broonie@kernel.org>
* ASoC: rt5660: use msleep() for long delayNicholas Mc Guire2017-01-121-1/+1
| | | | | | | | | | ulseep_range() uses hrtimers and provides no advantage over msleep() for larger delays. For this large delay msleep() is preferable.

* ASoC: rt5660: remove double constNicholas Mc Guire2017-01-121-2/+2
| | | | | | | | | Drop the const qualifier as it is being added by SOC_ENUM_DOUBLE_DECL() already which is called by SOC_ENUM_SINGLE_DECL() here.

* ASoC: rt5660: enable MCLK detectionBard Liao2016-10-241-0/+4
| | | | | | | | | There is a power saving mechanism in rt5660. It will turn off some unused power when MCLK is not present. We call that "MCLK detection" and it should be enabled by default. Signed-off-by: Bard Liao <bardliao@realtek.com> Signed-off-by: Mark Brown <broonie@kernel.org>
