[PATCH v2] ASoC: sunxi: DMIC: Add controls for adjusting the mic gains
by Joao Schim 30 Apr '24

30 Apr '24

The AllWinner H6 and later SoCs that sport a DMIC block contain a set of registers to control the gain (left + right) of each of the four supported channels. Add ASoC controls for changing each of the stereo channel gains using alsamixer and alike Signed-off-by: Joao Schim <joao(a)schimsalabim.eu> --- sound/soc/sunxi/sun50i-dmic.c | 34 ++++++++++++++++++++++++++++++++++ 1 file changed, 34 insertions(+) diff --git a/sound/soc/sunxi/sun50i-dmic.c b/sound/soc/sunxi/sun50i-dmic.c index c76628bc86c6..dd32780fb6a4 100644 --- a/sound/soc/sunxi/sun50i-dmic.c +++ b/sound/soc/sunxi/sun50i-dmic.c @@ -14,6 +14,7 @@ #include <sound/dmaengine_pcm.h> #include <sound/pcm_params.h> #include <sound/soc.h> +#include <sound/tlv.h> #define SUN50I_DMIC_EN_CTL (0x00) #define SUN50I_DMIC_EN_CTL_GLOBE BIT(8) @@ -43,6 +44,17 @@ #define SUN50I_DMIC_CH_NUM_N_MASK GENMASK(2, 0) #define SUN50I_DMIC_CNT (0x2c) #define SUN50I_DMIC_CNT_N (1 << 0) +#define SUN50I_DMIC_D0D1_VOL_CTR (0x30) + #define SUN50I_DMIC_D0D1_VOL_CTR_0R (0) + #define SUN50I_DMIC_D0D1_VOL_CTR_0L (8) + #define SUN50I_DMIC_D0D1_VOL_CTR_1R (16) + #define SUN50I_DMIC_D0D1_VOL_CTR_1L (24) +#define SUN50I_DMIC_D2D3_VOL_CTR (0x34) + #define SUN50I_DMIC_D2D3_VOL_CTR_2R (0) + #define SUN50I_DMIC_D2D3_VOL_CTR_2L (8) + #define SUN50I_DMIC_D2D3_VOL_CTR_3R (16) + #define SUN50I_DMIC_D2D3_VOL_CTR_3L (24) + #define SUN50I_DMIC_HPF_CTRL (0x38) #define SUN50I_DMIC_VERSION (0x50) @@ -273,8 +285,30 @@ static const struct of_device_id sun50i_dmic_of_match[] = { }; MODULE_DEVICE_TABLE(of, sun50i_dmic_of_match); +static const SNDRV_CTL_TLVD_DECLARE_DB_SCALE(sun50i_dmic_vol_scale, -12000, 75, 1); + +static const struct snd_kcontrol_new sun50i_dmic_controls[] = { + + SOC_DOUBLE_TLV("DMIC Channel 0 Capture Volume", SUN50I_DMIC_D0D1_VOL_CTR, + SUN50I_DMIC_D0D1_VOL_CTR_0L, SUN50I_DMIC_D0D1_VOL_CTR_0R, + 0xFF, 0, sun50i_dmic_vol_scale), + SOC_DOUBLE_TLV("DMIC Channel 1 Capture Volume", SUN50I_DMIC_D0D1_VOL_CTR, + SUN50I_DMIC_D0D1_VOL_CTR_1L, SUN50I_DMIC_D0D1_VOL_CTR_1R, + 0xFF, 0, sun50i_dmic_vol_scale), + SOC_DOUBLE_TLV("DMIC Channel 2 Capture Volume", SUN50I_DMIC_D2D3_VOL_CTR, + SUN50I_DMIC_D2D3_VOL_CTR_2L, SUN50I_DMIC_D2D3_VOL_CTR_2R, + 0xFF, 0, sun50i_dmic_vol_scale), + SOC_DOUBLE_TLV("DMIC Channel 3 Capture Volume", SUN50I_DMIC_D2D3_VOL_CTR, + SUN50I_DMIC_D2D3_VOL_CTR_3L, SUN50I_DMIC_D2D3_VOL_CTR_3R, + 0xFF, 0, sun50i_dmic_vol_scale), + + +}; + static const struct snd_soc_component_driver sun50i_dmic_component = { .name = "sun50i-dmic", + .controls = sun50i_dmic_controls, + .num_controls = ARRAY_SIZE(sun50i_dmic_controls), }; static int sun50i_dmic_runtime_suspend(struct device *dev) -- 2.25.1

[PATCH] ASoC: meson: cards: select SND_DYNAMIC_MINORS
by Jerome Brunet 30 Apr '24

30 Apr '24

Amlogic sound cards do create a lot of pcm interfaces, possibly more than 8. Some pcm interfaces are internal (like DPCM backends and c2c) and not exposed to userspace. Those interfaces still increase the number passed to snd_find_free_minor(), which eventually exceeds 8 causing -EBUSY error on card registration if CONFIG_SND_DYNAMIC_MINORS=n and the interface is exposed to userspace. select CONFIG_SND_DYNAMIC_MINORS for Amlogic cards to avoid the problem. Fixes: 7864a79f37b5 ("ASoC: meson: add axg sound card support") Signed-off-by: Jerome Brunet <jbrunet(a)baylibre.com> --- NOTE: This problem was found while toying with a minimal configuration which disabled CONFIG_SND_DYNAMIC_MINORS and DT overlays. Overlays prepend nodes instead of doing append. This changes the order in which the links are parsed by the card driver, which in turn changes the pcm numbers. The userpace pcm number then got over 8 triggering the problem. sound/soc/meson/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/sound/soc/meson/Kconfig b/sound/soc/meson/Kconfig index b93ea33739f2..6458d5dc4902 100644 --- a/sound/soc/meson/Kconfig +++ b/sound/soc/meson/Kconfig @@ -99,6 +99,7 @@ config SND_MESON_AXG_PDM config SND_MESON_CARD_UTILS tristate + select SND_DYNAMIC_MINORS config SND_MESON_CODEC_GLUE tristate -- 2.43.0

[DNM] common: pcm: hdmi/sof-hda-dsp/sof-soundwire: Syntax 7 dependent macro to generate the hdmi device sections
by GitHub pull_request - edited 30 Apr '24

30 Apr '24

alsa-project/alsa-ucm-conf pull request #413 was edited from ujfalusi: Hi, The PR will introduce a generic `HdmiDevice` macro, which can replace duplicated conditions in sof UCM files and potentially used by other devices to generate the needed section for the hdmi PCM devices to allow passthrough. The PR is marked as DNM and is in draft since the change depends on Syntax 7 support, which is only available in git version of alsa-lib, it is not a simple ask for a user (or developer) to use it and the change would break UCM for released alsa-lib. @perexg, is this something that you were suggesting? I think the macro and it's definition is generic enough, I hope that it will be usable for non SOF setups.

[PATCH v1 0/2] ALSA: hda: cs35l41: Ignore errors when configuring interrupts to allow laptops with bad ACPI to play audio
by Stefan Binding 30 Apr '24

30 Apr '24

Some laptops have a bad _CRS defined for its interrupt. This errors out inside the driver probe for CS35L41 HDA. However, there is no fix in software for this bad configuration, and it is unlikely to get a new BIOS, therefore it is better to allow the laptop to continue probe, instead of erroring out inside the probe. The interrupt is only used for Error Detection and recovery, without the interrupt the driver will continue to function, but errors will not be detected, and recovery will require a reboot. Also add support for ASUS ROG 2024 laptops. These laptops were released without _DSD, so need to be added into the CS35L41 config table. Quirks for these laptops already exist.

[PATCH 0/2][next] firewire: Avoid -Wflex-array-member-not-at-end warnings
by Gustavo A. R. Silva 29 Apr '24

29 Apr '24

-Wflex-array-member-not-at-end is coming in GCC-14, and we are getting ready to enable it globally. So, we are deprecating flexible-array members in the middle of another struct. There are currently a couple of local structures (`u` and `template`) that are using a flexible `struct fw_iso_packet` as header for a couple of on-stack arrays. We make use of the `struct_group_tagged()` helper to separate the flexible array from the rest of the members in the flexible structure, and, with this, we can now declare objects of the type of the tagged struct, without embedding the flexible array in the middle of another struct. We also use `container_of()` whenever we need to retrieve a pointer to the flexible structure, through which the flexible-array member can be accessed. With these changes, we fix a couple of -Wflex-array-member-not-at-end warnings. Gustavo A. R.
