From 43d2c4982fcc6ed0adfea1275bc6df28bc48c1ea Mon Sep 17 00:00:00 2001 From: Angelo Dureghello Date: Sat, 21 Aug 2021 10:26:56 +0200 Subject: [PATCH] ASoC: ics43432: add CMM-4030D-261 support Despite minimal datasheet differences, the driver seems perfectly compatible with CMM-4030D-261. Tested CMM-4030D-261 to work with this changes: / { cmm4030d: cmm4030d { #sound-dai-cells = <0>; compatible = "cui,cmm-4030d-261"; }; sound_mic { compatible = "simple-audio-card"; simple-audio-card,name = "i2s mem mic"; simple-audio-card,format = "i2s"; simple-audio-card,bitclock-master = <&sound_master>; simple-audio-card,frame-master = <&sound_master>; sound_master: simple-audio-card,cpu { sound-dai = <&ssi2>; system-clock-frequency = <2822400>; }; simple-audio-card,codec { sound-dai = <&cmm4030d>; }; }; }; Audio has been captured and tested successfully by: arecord -D "hw:1,0" -f S24_LE > test.wav aplay test.wav Signed-off-by: Angelo Dureghello Link: https://lore.kernel.org/r/20210821082658.4147595-1-angelo.dureghello@timesys.com Signed-off-by: Mark Brown --- sound/soc/codecs/Kconfig | 2 +- sound/soc/codecs/ics43432.c | 4 +++- 2 files changed, 4 insertions(+), 2 deletions(-) diff --git a/sound/soc/codecs/Kconfig b/sound/soc/codecs/Kconfig index fe5e558635ad..82ee233a269d 100644 --- a/sound/soc/codecs/Kconfig +++ b/sound/soc/codecs/Kconfig @@ -848,7 +848,7 @@ config SND_SOC_HDAC_HDA select SND_HDA config SND_SOC_ICS43432 - tristate + tristate "ICS43423 and compatible i2s microphones" config SND_SOC_INNO_RK3036 tristate "Inno codec driver for RK3036 SoC" diff --git a/sound/soc/codecs/ics43432.c b/sound/soc/codecs/ics43432.c index 47e749f03940..de4c8460ab3d 100644 --- a/sound/soc/codecs/ics43432.c +++ b/sound/soc/codecs/ics43432.c @@ -1,6 +1,7 @@ // SPDX-License-Identifier: GPL-2.0-only /* - * I2S MEMS microphone driver for InvenSense ICS-43432 + * I2S MEMS microphone driver for InvenSense ICS-43432 and similar + * MEMS-based microphones. * * - Non configurable. * - I2S interface, 64 BCLs per frame, 32 bits per channel, 24 bit data @@ -53,6 +54,7 @@ static int ics43432_probe(struct platform_device *pdev) #ifdef CONFIG_OF static const struct of_device_id ics43432_ids[] = { { .compatible = "invensense,ics43432", }, + { .compatible = "cui,cmm-4030d-261", }, { } }; MODULE_DEVICE_TABLE(of, ics43432_ids); -- 2.39.5
