Dell privacy led trigger driver will ack EC when micmute key pressed through this micphone led control interface like hda_generic provided ACPI method defined in dell-privacy micmute led trigger will be called for notifying the EC that software mute has been completed, then hardware audio circuit solution controlled by EC will switch the audio input source off/on Signed-off-by: Perry Yuan -------- v3 -> v4: * remove unused debug log * remove compile flag of DELL privacy * move the micmute_led to local from rt715_priv * when Jaroslav upstream his gerneric LED trigger driver,I will rebase this patch,please consider merge this at first https://lore.kernel.org/alsa-devel/20210211111400.1131020-1-perex@perex.cz/ v2 -> v3: * simplify the patch to reuse some val value * add more detail to the commit info v1 -> v2: * fix some format issue -------- --- sound/soc/codecs/rt715-sdca.c | 12 ++++++++++++ sound/soc/codecs/rt715.c | 12 ++++++++++++ 2 files changed, 24 insertions(+) diff --git a/sound/soc/codecs/rt715-sdca.c b/sound/soc/codecs/rt715-sdca.c index b43ac8559e45..816348ae11a1 100644 --- a/sound/soc/codecs/rt715-sdca.c +++ b/sound/soc/codecs/rt715-sdca.c @@ -12,6 +12,7 @@ #include #include #include +#include #include #include #include @@ -269,6 +270,7 @@ static int rt715_sdca_put_volsw(struct snd_kcontrol *kcontrol, unsigned int reg = mc->reg; unsigned int max = mc->max; int err; + bool micmute_led; val = ucontrol->value.integer.value[0]; if (invert) @@ -287,6 +289,16 @@ static int rt715_sdca_put_volsw(struct snd_kcontrol *kcontrol, return err; } + /* Micmute LED state changed by muted/unmute switch */ + if (mc->invert) { + if (ucontrol->value.integer.value[0] || ucontrol->value.integer.value[1]) { + micmute_led = LED_OFF; + } else { + micmute_led = LED_ON; + } + ledtrig_audio_set(LED_AUDIO_MICMUTE, micmute_led); + } + return 0; } diff --git a/sound/soc/codecs/rt715.c b/sound/soc/codecs/rt715.c index cdcba70146da..db2c0d2ff9d2 100644 --- a/sound/soc/codecs/rt715.c +++ b/sound/soc/codecs/rt715.c @@ -13,6 +13,7 @@ #include #include #include +#include #include #include #include @@ -88,6 +89,7 @@ static int rt715_set_amp_gain_put(struct snd_kcontrol *kcontrol, RT715_SET_GAIN_MIX_ADC2_L}; unsigned int addr_h, addr_l, val_h, val_ll, val_lr; unsigned int read_ll, read_rl, i, j, loop_cnt; + bool micmute_led; if (strstr(ucontrol->id.name, "Main Capture Switch") || strstr(ucontrol->id.name, "Main Capture Volume")) @@ -95,6 +97,16 @@ static int rt715_set_amp_gain_put(struct snd_kcontrol *kcontrol, else loop_cnt = 1; + /* Micmute LED state changed by muted/unmute switch */ + if (mc->invert) { + if (ucontrol->value.integer.value[0] || ucontrol->value.integer.value[1]) { + micmute_led = LED_OFF; + } else { + micmute_led = LED_ON; + } + ledtrig_audio_set(LED_AUDIO_MICMUTE, micmute_led); + } + for (j = 0; j < loop_cnt; j++) { /* Can't use update bit function, so read the original value first */ if (loop_cnt == 1) {
