From 7ae7434086f5b106021276e88b8ef49debf30aa8 Mon Sep 17 00:00:00 2001 From: Vinod Koul Date: Thu, 10 Feb 2011 12:58:01 +0530 Subject: ASoC: mid-x86: Use the soc-jack apis for jack type detection This patch modifies the mfld_machine to use the new jack apis for adding the voltage zones for jack type detection. It also modifed TI sn95031 codec driver to use these new apis Signed-off-by: Vinod Koul Signed-off-by: Harsha Priya Acked-by: Liam Girdwood Signed-off-by: Mark Brown --- sound/soc/codecs/sn95031.c | 4 +--- sound/soc/mid-x86/mfld_machine.c | 12 ++++++++++++ 2 files changed, 13 insertions(+), 3 deletions(-) diff --git a/sound/soc/codecs/sn95031.c b/sound/soc/codecs/sn95031.c index 4cc00177ee3..d0b78020671 100644 --- a/sound/soc/codecs/sn95031.c +++ b/sound/soc/codecs/sn95031.c @@ -782,9 +782,7 @@ static int sn95031_get_headset_state(struct snd_soc_jack *mfld_jack) { int micbias = sn95031_get_mic_bias(mfld_jack->codec); - /* Defaulting to HEADSET for now. - * will change after adding soc-jack detection apis */ - int jack_type = SND_JACK_HEADSET; + int jack_type = snd_soc_jack_get_type(mfld_jack, micbias); pr_debug("jack type detected = %d\n", jack_type); if (jack_type == SND_JACK_HEADSET) diff --git a/sound/soc/mid-x86/mfld_machine.c b/sound/soc/mid-x86/mfld_machine.c index 45a00670802..96487fb8d26 100644 --- a/sound/soc/mid-x86/mfld_machine.c +++ b/sound/soc/mid-x86/mfld_machine.c @@ -74,6 +74,12 @@ static struct snd_soc_jack_pin mfld_jack_pins[] = { }, }; +/* jack detection voltage zones */ +static struct snd_soc_jack_zone mfld_zones[] = { + {MFLD_MV_START, MFLD_MV_AM_HS, SND_JACK_HEADPHONE}, + {MFLD_MV_AM_HS, MFLD_MV_HS, SND_JACK_HEADSET}, +}; + /* sound card controls */ static const char *headset_switch_text[] = {"Earpiece", "Headset"}; @@ -264,6 +270,12 @@ static int mfld_init(struct snd_soc_pcm_runtime *runtime) pr_err("adding jack pins failed\n"); return ret_val; } + ret_val = snd_soc_jack_add_zones(&mfld_jack, + ARRAY_SIZE(mfld_zones), mfld_zones); + if (ret_val) { + pr_err("adding jack zones failed\n"); + return ret_val; + } /* we want to check if anything is inserted at boot, * so send a fake event to codec and it will read adc -- cgit v1.2.3
