[PATCH v2 0/6] ASoC: Drop or replace of_gpio.h
by Andy Shevchenko 07 Jun '24

07 Jun '24

Replace or drop the legacy header that is subject to remove. Not all of them were compile-tested, the series might have hidden compilation errors. In v3: - moved aw88399 from the "Remove ..." patch to the "Replace ..." (LKP) In v2: - added tags (Kuninori, Charles) - ripped out TAS2781 (it's a mess from GPIO handling perspective) Andy Shevchenko (6): ASoC: codecs: Remove unused of_gpio.h ASoC: fsl: Remove unused of_gpio.h ASoC: rockchip: Remove unused of_gpio.h ASoC: codecs: Replace of_gpio.h by proper one ASoC: generic: Replace of_gpio.h by proper one ASoC: samsung: Replace of_gpio.h by proper one sound/soc/codecs/ak4118.c | 1 - sound/soc/codecs/ak4458.c | 1 - sound/soc/codecs/aw88395/aw88395.c | 2 +- sound/soc/codecs/aw88399.c | 2 +- sound/soc/codecs/cs53l30.c | 1 - sound/soc/codecs/max98390.c | 1 - sound/soc/codecs/pcm3168a.c | 1 - sound/soc/codecs/rk817_codec.c | 1 - sound/soc/codecs/tas2552.c | 1 - sound/soc/codecs/tas2764.c | 1 - sound/soc/codecs/tas2770.c | 1 - sound/soc/codecs/tas2780.c | 1 - sound/soc/codecs/tlv320adc3xxx.c | 1 - sound/soc/codecs/tlv320adcx140.c | 1 - sound/soc/codecs/tlv320aic31xx.c | 1 - sound/soc/codecs/ts3a227e.c | 1 - sound/soc/codecs/wsa883x.c | 1 - sound/soc/fsl/imx-es8328.c | 1 - sound/soc/fsl/imx-rpmsg.c | 2 -- sound/soc/generic/audio-graph-card2-custom-sample.c | 3 ++- sound/soc/rockchip/rockchip_i2s.c | 1 - sound/soc/rockchip/rockchip_spdif.c | 1 - sound/soc/samsung/aries_wm8994.c | 2 +- 23 files changed, 5 insertions(+), 24 deletions(-) -- 2.43.0.rc1.1336.g36b5255a03ac

[PATCH v2 0/2] tlv320adc3xxx: Allow MICBIAS pins to be used as GPOs
by Ricard Wanderlof 07 Jun '24

07 Jun '24

In some cases, depending on system design, the MICBIAS pins on the chip are not needed as such, but a couple of extra GPIO pins would be useful. This patch allows the MICBIAS pins to be configured in the device tree as general purpose output pins, controlled via the GPIO framework. Owing to their originally intended purpose there are some limitations: when the MICBIAS pins are deactivated, they will float, so will likely need a pulldown in many applications. When activated, they will assume the voltage specified by the micbias1-vg and micbias2-vg properties, respectively, meaning that the resulting output voltage will be 2.0 V, 2.5 V or AVDD . Signed-off-by: Ricard Wanderlof <ricard.wanderlof(a)axis.com> --- Changes in v2: - Corrected typo in yaml document for ti,micbias2-vg property reference - Added dependecies to yaml document for ti,micbias1-gio and ti,micbias2-gpo - Link to v1: https://lore.kernel.org/r/20240529-tlv320adc3xxx-micbias-gpo-v1-0-300d39cec… --- Ricard Wanderlof (2): ASoC: dt-bindings: tlv320adc3xxx: Add MICBIAS-as-GPO properties tlv320adc3xxx: Add support for using MICBIAS pins as GPO .../bindings/sound/ti,tlv320adc3xxx.yaml | 24 +++++ sound/soc/codecs/tlv320adc3xxx.c | 105 ++++++++++++++++----- 2 files changed, 108 insertions(+), 21 deletions(-) --- base-commit: 47d09270d7776e46858a161f94b735640b2fb056 change-id: 20240528-tlv320adc3xxx-micbias-gpo-b8b4d1c846d3 Best regards, -- -- Ricard Wolf Wanderlof ricardw(at)axis.com Axis Communications AB, Lund, Sweden www.axis.com Phone +46 46 272 2016 Fax +46 46 13 61 30

[PATCHv4 9/9] ASoC: dt-bindings: fsl-asoc-card: add compatible for generic codec
by Elinor Montmasson 06 Jun '24

06 Jun '24

Add documentation about new dts bindings following new support for compatible "fsl,imx-audio-generic". Some CPU DAI don't require a real audio codec. The new compatible "fsl,imx-audio-generic" allows using the driver with codec drivers SPDIF DIT and SPDIF DIR as dummy codecs. It also allows using not pre-configured audio codecs which don't require specific control through a codec driver. The new dts properties give the possibility to set some parameters about the CPU DAI usually set through the codec configuration.
