Perhaps what you need here is some comments then - the way you fiddle about with the bitmasks afterwards doesn't make it sufficient obvious.

[alsa-devel] [PATCH 00/13] ASoC: Componentization: Unified probe/remove path
by Lars-Peter Clausen 19 Aug '14

19 Aug '14

This patch-set starts with consolidating the probe and remove paths of snd_soc_codec and snd_soc_platform drivers. Once that has been done it uses the new generic paths to also add probe and remove support to snd_soc_component drivers. With that in place the AUX dev handling is then moved to the component layer as there is no longer any snd_soc_codec specifics required to handle them. The later patches in the series deal with cleaning things up and consolidating a few code paths between CPU and CODEC DAI handling. After this patch-set the core of the ASoC core is now fully componentized and doesn't care anymore (except for one small hack which is documented in the commit) about whether something is a snd_soc_codec, snd_soc_platform or snd_soc_component. This does unfortunately not mean that componentization is done yet. There are still a few things left to do. This includes bringing more things to the component level for example clock and PCM handling. There is also still the issue that we handle CPU DAIs and CODEC DAIs differently. For CODEC DAIs the capture stream is output and the playback stream is input while it is the other way around for CPU DAIs. Also we expect them to handle the SND_SOC_DAIFMT_CBx_CFx settings depending on whether they are a CPU or CODEC DAI. So we need a way to distinguish between the two. At this point it is already possible though to convert simple snd_soc_codec drivers that don't need any of this (e.g. some of the external amplifier drivers) to snd_soc_components. Since the series adds a centralized path for probing and removing it also paves the way towards easier integration of the drivers/base/component.c framework, which in turn will allow some cleanups and to fix some long standing bugs in the way hot-unplug is handled (or rather not handled). - Lars Lars-Peter Clausen (13): ASoC: Move debugfs registration to the component level ASoC: Consolidate platform and CODEC probe/remove ASoC: Make rtd->codec optional ASoC: Add component level probe/remove support ASoC: Move AUX dev support to the component level ASoC: Pass component instead of DAPM context to AUX dev init callback ASoC: Move component->probed check into soc_{remove,probe}_component() ASoC: Cleanup DAI module reference counting ASoC: Consolidate CPU and CODEC DAI removal ASoC: Consolidate CPU and CODEC DAI look-up ASoC: Automatically initialize regmap for all components ASoC: Remove support for legacy snd_soc_platform IO ASoC: Replace list_empty(&card->codec_dev_list) with !card->instantiated include/sound/soc.h | 67 ++-- sound/soc/samsung/speyside.c | 6 +- sound/soc/soc-core.c | 667 ++++++++++++++++------------------ sound/soc/soc-generic-dmaengine-pcm.c | 4 +- sound/soc/soc-io.c | 28 -- 5 files changed, 357 insertions(+), 415 deletions(-) -- 1.8.0

[alsa-devel] [PATCH] ASoC: fsl: Fix building of imx-es8328 on PPC
by Sean Cross 19 Aug '14

19 Aug '14

The imx-es8328 driver fails to build on PPC because it explicitly depends on SND_SOC_IMX_PCM_FIQ, which itself doesn't build on PPC. Instead, rely on the SND_SOC_FSL_SSI config option to pull in the necessary libraries. While we're at it, remove SND_SOC_FSL_UTILS, which also is not needed.

[alsa-devel] [PATCH v4 2/2] mfd: arizona: Update DT binding to support INn_MODE init_data
by Inha Song 19 Aug '14

19 Aug '14

This patch update DT binding to support INn_MODE init_data. Each input signal path can be configurated either as a Analogue or Digital using the INn_MODE registers.

[alsa-devel] [PATCH v4 1/2] mfd: arizona: Add support for INn_Mode register control
by Inha Song 19 Aug '14

19 Aug '14

Some boards need to set the INn_MODE[1:0] register to change the input signal patch. This wlf,inmode property is optional. If present, values must be specified less than or equal to the number of input singals. If values less than the number of input signals, elements that has not been specifed are set to 0 by default. Example: - wlf,inmode = <2 0 2>; /* IN1, IN3 use DMIC */ Signed-off-by: Inha Song <ideal.song(a)samsung.com> Reviewed-by: Charles Keepax <ckeepax(a)opensource.wolfsonmicro.com> --- drivers/mfd/arizona-core.c | 8 +++++++- 1 file changed, 7 insertions(+), 1 deletion(-) diff --git a/drivers/mfd/arizona-core.c b/drivers/mfd/arizona-core.c index 10a0cb9..81e6db8 100644 --- a/drivers/mfd/arizona-core.c +++ b/drivers/mfd/arizona-core.c @@ -534,7 +534,7 @@ EXPORT_SYMBOL_GPL(arizona_of_get_named_gpio); static int arizona_of_get_core_pdata(struct arizona *arizona) { struct arizona_pdata *pdata = &arizona->pdata; - int ret, i; + int ret, i, proplen; pdata->reset = arizona_of_get_named_gpio(arizona, "wlf,reset", true); @@ -560,6 +560,12 @@ static int arizona_of_get_core_pdata(struct arizona *arizona) ret); } + proplen = of_property_count_u32_elems(arizona->dev->of_node, + "wlf,inmode"); + if (proplen > 0 && proplen <= ARRAY_SIZE(arizona->pdata.inmode)) + of_property_read_u32_array(arizona->dev->of_node, "wlf,inmode", + arizona->pdata.inmode, proplen); + return 0; } -- 2.0.0.390.gcb682f8
