The patch ASoC: hdmi-codec: add .get_dai_id support has been applied to the asoc tree at git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 96203fb4237bf70f0fd0fa307ca2975077db3ceb Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Date: Thu, 18 May 2017 01:40:20 +0000 Subject: [PATCH] ASoC: hdmi-codec: add .get_dai_id support ALSA SoC needs to know connected DAI ID for probing. It is not a big problem if device/driver was only for sound, but getting DAI ID will be difficult if device includes both Video/Sound, like HDMI. To solve this issue, this patch adds new .get_dai_id callback on hdmi_codec_ops Signed-off-by: Kuninori Morimoto <kuninori.morimoto.gx@xxxxxxxxxxx> Signed-off-by: Mark Brown <broonie@xxxxxxxxxx> --- include/sound/hdmi-codec.h | 9 +++++++++ sound/soc/codecs/hdmi-codec.c | 13 +++++++++++++ 2 files changed, 22 insertions(+) diff --git a/include/sound/hdmi-codec.h b/include/sound/hdmi-codec.h index 915c4357945c..9483c55f871b 100644 --- a/include/sound/hdmi-codec.h +++ b/include/sound/hdmi-codec.h @@ -18,9 +18,11 @@ #ifndef __HDMI_CODEC_H__ #define __HDMI_CODEC_H__ +#include <linux/of_graph.h> #include <linux/hdmi.h> #include <drm/drm_edid.h> #include <sound/asoundef.h> +#include <sound/soc.h> #include <uapi/sound/asound.h> /* @@ -87,6 +89,13 @@ struct hdmi_codec_ops { */ int (*get_eld)(struct device *dev, void *data, uint8_t *buf, size_t len); + + /* + * Getting DAI ID + * Optional + */ + int (*get_dai_id)(struct snd_soc_component *comment, + struct device_node *endpoint); }; /* HDMI codec initalization data */ diff --git a/sound/soc/codecs/hdmi-codec.c b/sound/soc/codecs/hdmi-codec.c index 8659b76b066a..6d05161b625d 100644 --- a/sound/soc/codecs/hdmi-codec.c +++ b/sound/soc/codecs/hdmi-codec.c @@ -719,6 +719,18 @@ static const struct snd_soc_dai_driver hdmi_spdif_dai = { .pcm_new = hdmi_codec_pcm_new, }; +static int hdmi_of_xlate_dai_id(struct snd_soc_component *component, + struct device_node *endpoint) +{ + struct hdmi_codec_priv *hcp = snd_soc_component_get_drvdata(component); + int ret = -ENOTSUPP; /* see snd_soc_get_dai_id() */ + + if (hcp->hcd.ops->get_dai_id) + ret = hcp->hcd.ops->get_dai_id(component, endpoint); + + return ret; +} + static struct snd_soc_codec_driver hdmi_codec = { .component_driver = { .controls = hdmi_controls, @@ -727,6 +739,7 @@ static struct snd_soc_codec_driver hdmi_codec = { .num_dapm_widgets = ARRAY_SIZE(hdmi_widgets), .dapm_routes = hdmi_routes, .num_dapm_routes = ARRAY_SIZE(hdmi_routes), + .of_xlate_dai_id = hdmi_of_xlate_dai_id, }, }; -- 2.11.0 _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
