[PATCH 00/14] MFD/extcon/ASoC: Add support for Intel Bay Trail boards with WM5102 codec
by Hans de Goede 16 Jan '21

16 Jan '21

Hi All, This patch series adds support for Intel Bay Trail based device which use a WM5102 codec for audio output/input. This was developed and tested on a Lenovo Yoga Tablet 1051L. This series consists of 3 parts: 1. Arizona MFD drv patches for ACPI bindings, better jack-detect support and misc. fixes 2. extcon-arizona driver fixes and improved jack reporting (this depends on the MFD changes) 3. ASoC patches in the form of a quirk for BYTCR detecting, a new machine driver for BYT + WM5102 and jack-detect support for the new machine driver (which again depends on the MFD changes). Given that 2. and 3. depend on the MFD changes I believe that it is best if all patches in this series are merged through the MFD tree (once reviewed and acked) and then Lee can provide a immutable branch for the ASoC and extcon maintainers to merge into their trees. I have a patch with matching UCM profile changes available here: https://github.com/jwrdegoede/alsa-ucm-conf/commit/316109e7814926ba984322c1… This series + the UCM profile has been tested with both the SST and SOF ASoC drivers for BYT devices.

[PATCH 1/2] ASoC: qcom: lpass: Fix hardcoded SC7810 DAI IDs
by Stephan Gerhold 15 Jan '21

15 Jan '21

LPASS is broken on MSM8916/DragonBoard 410c since Linux 5.10. Attempting to play HDMI audio results in: ADV7533: lpass_platform_pcmops_hw_params: invalid interface: 3 ADV7533: lpass_platform_pcmops_trigger: invalid 3 interface apq8016-lpass-cpu 7708000.audio-controller: ASoC: error at soc_component_trigger on 7708000.audio-controller: -22 Attempting to record analog audio results in: Unable to handle kernel NULL pointer dereference at virtual address 00000000000001e4 Internal error: Oops: 96000004 [#1] PREEMPT SMP CPU: 1 PID: 1568 Comm: arecord Not tainted 5.11.0-rc3 #20 Hardware name: Qualcomm Technologies, Inc. APQ 8016 SBC (DT) pc : regmap_write+0x14/0x80 lr : lpass_platform_pcmops_open+0xd8/0x210 [snd_soc_lpass_platform] Call trace: regmap_write+0x14/0x80 lpass_platform_pcmops_open+0xd8/0x210 [snd_soc_lpass_platform] snd_soc_component_open+0x2c/0x94 ... The problem was introduced in commit 7cb37b7bd0d3 ("ASoC: qcom: Add support for lpass hdmi driver"). The mistake made there is that lpass.h now contains #include <dt-bindings/sound/sc7180-lpass.h> and then the SC7810 DAI IDs are hardcoded all over lpass-cpu.c and lpass-platform.c. But apq8016 and ipq806x have completely different DAI IDs so now MI2S_QUATERNARY (HDMI) is invalid and MI2S_TERTIARY (= LPASS_DP_RX in sc7180-lpass.h) is treated as HDMI port. Therefore, LPASS is broken on all platforms except SC7810. This commit fixes the problem by removing the include from lpass.h. To check if a DAI is an HDMI port, we compare the dai_id with a new "hdmi_dai" variable in lpass_variant. For SC7180 this is set to LPASS_DP_RX (as before), for all other platform to some unrealistic value (UINT_MAX). Cc: Srinivasa Rao Mandadapu <srivasam(a)codeaurora.org> Cc: Srinivas Kandagatla <srinivas.kandagatla(a)linaro.org> Fixes: 7cb37b7bd0d3 ("ASoC: qcom: Add support for lpass hdmi driver") Signed-off-by: Stephan Gerhold <stephan(a)gerhold.net> --- Srinivas mentioned a potential different fix here: https://lore.kernel.org/alsa-devel/4b34bd4f-e7bc-84f9-5e8a-b2348c17b7aa@lin… Instead of this patch, we could change the dt-bindings for LPASS, so that all SoCs use consistent DAI IDs. In general, I think this might be cleaner, especially in case more special DAIs are added in the future. However, when I made this patch (before Srinivas mentioned it) I tried to avoid changing the dt-bindings because: - Changing dt-bindings after they are added is generally discouraged. but more importantly: - lpass-ipq806x.c does not seem to have PRIMARY, SECONDARY, ... but something completely different. I know nothing about that platform so I don't know how to handle it. --- sound/soc/qcom/lpass-apq8016.c | 1 + sound/soc/qcom/lpass-cpu.c | 9 ++-- sound/soc/qcom/lpass-ipq806x.c | 1 + sound/soc/qcom/lpass-lpaif-reg.h | 2 +- sound/soc/qcom/lpass-platform.c | 77 +++++++++++--------------------- sound/soc/qcom/lpass-sc7180.c | 1 + sound/soc/qcom/lpass.h | 4 +- 7 files changed, 39 insertions(+), 56 deletions(-) diff --git a/sound/soc/qcom/lpass-apq8016.c b/sound/soc/qcom/lpass-apq8016.c index 8507ef8f6679..40e9c66a74a9 100644 --- a/sound/soc/qcom/lpass-apq8016.c +++ b/sound/soc/qcom/lpass-apq8016.c @@ -273,6 +273,7 @@ static struct lpass_variant apq8016_data = { .num_clks = 2, .dai_driver = apq8016_lpass_cpu_dai_driver, .num_dai = ARRAY_SIZE(apq8016_lpass_cpu_dai_driver), + .hdmi_dai = LPASS_HDMI_DAI_UNSUPPORTED, .dai_osr_clk_names = (const char *[]) { "mi2s-osr-clk0", "mi2s-osr-clk1", diff --git a/sound/soc/qcom/lpass-cpu.c b/sound/soc/qcom/lpass-cpu.c index c5e99c2d89c7..b22992050646 100644 --- a/sound/soc/qcom/lpass-cpu.c +++ b/sound/soc/qcom/lpass-cpu.c @@ -707,7 +707,8 @@ static unsigned int of_lpass_cpu_parse_sd_lines(struct device *dev, } static void of_lpass_cpu_parse_dai_data(struct device *dev, - struct lpass_data *data) + struct lpass_data *data, + struct lpass_variant *variant) { struct device_node *node; int ret, id; @@ -724,7 +725,7 @@ static void of_lpass_cpu_parse_dai_data(struct device *dev, dev_err(dev, "valid dai id not found: %d\n", ret); continue; } - if (id == LPASS_DP_RX) { + if (id == variant->hdmi_dai) { data->hdmi_port_enable = 1; dev_err(dev, "HDMI Port is enabled: %d\n", id); } else { @@ -766,7 +767,7 @@ int asoc_qcom_lpass_cpu_platform_probe(struct platform_device *pdev) drvdata->variant = (struct lpass_variant *)match->data; variant = drvdata->variant; - of_lpass_cpu_parse_dai_data(dev, drvdata); + of_lpass_cpu_parse_dai_data(dev, drvdata, variant); res = platform_get_resource_byname(pdev, IORESOURCE_MEM, "lpass-lpaif"); @@ -820,7 +821,7 @@ int asoc_qcom_lpass_cpu_platform_probe(struct platform_device *pdev) for (i = 0; i < variant->num_dai; i++) { dai_id = variant->dai_driver[i].id; - if (dai_id == LPASS_DP_RX) + if (dai_id == variant->hdmi_dai) continue; drvdata->mi2s_osr_clk[dai_id] = devm_clk_get(dev, diff --git a/sound/soc/qcom/lpass-ipq806x.c b/sound/soc/qcom/lpass-ipq806x.c index 92f98b4df47f..a0c7c5eb03f1 100644 --- a/sound/soc/qcom/lpass-ipq806x.c +++ b/sound/soc/qcom/lpass-ipq806x.c @@ -149,6 +149,7 @@ static struct lpass_variant ipq806x_data = { .dai_driver = &ipq806x_lpass_cpu_dai_driver, .num_dai = 1, + .hdmi_dai = LPASS_HDMI_DAI_UNSUPPORTED, .dai_osr_clk_names = (const char *[]) { "mi2s-osr-clk", }, diff --git a/sound/soc/qcom/lpass-lpaif-reg.h b/sound/soc/qcom/lpass-lpaif-reg.h index 405542832e99..332f1b9ba674 100644 --- a/sound/soc/qcom/lpass-lpaif-reg.h +++ b/sound/soc/qcom/lpass-lpaif-reg.h @@ -133,7 +133,7 @@ #define LPAIF_WRDMAPERCNT_REG(v, chan) LPAIF_WRDMA_REG_ADDR(v, 0x14, (chan)) #define LPAIF_INTFDMA_REG(v, chan, reg, dai_id) \ - ((v->dai_driver[dai_id].id == LPASS_DP_RX) ?

[PATCH v4 0/6] Add support for Rpi4b + Cirrus Lochnagar2 and CS47L15
by Richard Fitzgerald 15 Jan '21

15 Jan '21

This set of patches provides support for using the Raspberry Pi 4b with a Cirrus Logic Lochnagar 2 audio development platform plus Cirrus Logic CS47L15 codec. Patches are needed to audio-graph-card to enable support for setting the component sysclks and plls. These are not specific to CS47L15 - several Cirrus and non-Cirrus codecs also require component clock setup, typically for larger codecs with multiple internal clocking options and clock domains. The codec sysclks and plls cannot be placed under the clock framework because they are typically I2C/SPI/Soundwire-connected peripherals and access to the registers would cause a nested get of the bus clock. The clock framework does not support this and it would result in a deadlock.

[PATCH 0/4] ASoC: qcom: Minor code cleanups for lpass-cpu
by Stephen Boyd 15 Jan '21

15 Jan '21

Here's some minor code cleanups for the lpass-cpu driver. I noticed that it casts away const from the driver data from DT. That's not great but fixing it is a little more involved. I'll get to it later. There's also some questionable clk_get() usage that should probably be clk_get_optional(). For now this should help a little.

Looking through the code it feels like there's a lot of things that are written with mostly duplicated code that differs only in data so you could shrink things down a lot by refactoring things to have one copy of the code and pass different data into it. > Enable support for the platform which uses MT6359 as > external codec device. > +config SND_SOC_MT6359_ACCDET Missing blank line here. > +++ b/sound/soc/codecs/mt6359-accdet.c > @@ -0,0 +1,1951 @@ > +// SPDX-License-Identifier: GPL-2.0 > +/* > + * Copyright (C) 2021 MediaTek Inc.

There's extensive use of global data here, and lots of raw pr_ prints rather than dev_ prints as well - this doesn't look like how a Linux driver is supposed to be written. > + > +const struct of_device_id mt6359_accdet_of_match[] = { > + { > + .compatible = "mediatek,mt6359-accdet", > + .data = &mt6359_accdet, Given that this is specific to a particular PMIC why does this need a compatible string? > +/* global function declaration */ > + > +static u64 mt6359_accdet_get_current_time(void) > +{ > + return sched_clock(); > +} It is probably best to remove this wrapper. > +static bool mt6359_accdet_timeout_ns(u64 start_time_ns, u64 timeout_time_ns) > +{ > + u64 cur_time = 0; > + u64 elapse_time = 0; > + > + /* get current tick, ns */ > + cur_time = mt6359_accdet_get_current_time(); > + if (cur_time < start_time_ns) { > + start_time_ns = cur_time; > + /* 400us */ > + timeout_time_ns = 400 * 1000; > + } > + elapse_time = cur_time - start_time_ns; > + > + /* check if timeout */ > + if (timeout_time_ns <= elapse_time) > + return false; > + > + return true; > +} There must be a generic implementation of this already surely? > +static unsigned int check_key(unsigned int v) > +{ This looks a lot like open coding of the functionality of the extcon adc_jack functionality. > +static void send_key_event(unsigned int keycode, unsigned int flag) > +{ > + int report = 0; > + > + switch (keycode) { > + case DW_KEY: > + if (flag != 0) > + report = SND_JACK_BTN_1; What does flag mean?

All this interrupt handling code is really extremely difficult to follow, there's *lots* of functions all open coding many individual register bits sometimes redundantly and it's very hard to follow what it's supposed to be doing. I can't help but think that in addition to making things data driven writing more linear code without these abstraction layers would help a lot with comprehensibility. > +static irqreturn_t mtk_accdet_irq_handler_thread(int irq, void *data) > +{ > + accdet_irq_handle(); > + > + return IRQ_HANDLED; > +} Why does this wrapper function exist - AFAICT it's just introducing a bug given that the called function is able to detect spurious interrupts but this unconditionally reports IRQ_HANDLED. > +int mt6359_accdet_init(struct snd_soc_component *component, > + struct snd_soc_card *card) > +{ > + int ret = 0; > + struct mt63xx_accdet_data *priv = > + snd_soc_card_get_drvdata(component->card); > + > + return ret; > +} > +EXPORT_SYMBOL_GPL(mt6359_accdet_init); This is a weird interface, what's going on here? > +int mt6359_accdet_set_drvdata(struct snd_soc_card *card) > +{ > + snd_soc_card_set_drvdata(card, accdet); > + > + return 0; > +} > +EXPORT_SYMBOL_GPL(mt6359_accdet_set_drvdata); This is setting off *massive* alarm bells in that it seems to try to claim the card level driver data for this specific driver, again what's going on here? > +module_init(mt6359_accdet_soc_init); > +module_exit(mt6359_accdet_soc_exit); module_platform_driver()

[PATCH v2 0/5] Clock and reset improvements for Tegra ALSA drivers
by Dmitry Osipenko 15 Jan '21

15 Jan '21

This series improves the handling of clock and reset controls of NVIDA Tegra ALSA drivers. Tegra HDA and AHUB drivers aren't handling resets properly, which needs to be fixed in order to unblock other patches related to fixes of the reset controller driver since HDA/AHUB are bound to fail once reset controller driver will be corrected. In particular ALSA drivers are relying on implicit de-assertion of resets which is done by the tegra-clk driver. It's not the business of the clk driver to touch resets and we need to fix this because it breaks reset/clk programming sequences of other Tegra drivers. Changelog: v2: - Added regcache_sync() to the "ahub: Reset hardware properly" patch, which was missed by accident in v1. - Corrected typo in the format of the error message in "ahub: Use of_reset_control_array_get_exclusive()" patch by s/%p/%pe/. Dmitry Osipenko (5): ALSA: hda/tegra: Use clk_bulk helpers ALSA: hda/tegra: Reset hardware ASoC: tegra: ahub: Use of_reset_control_array_get_exclusive() ASoC: tegra: ahub: Use clk_bulk helpers ASoC: tegra: ahub: Reset hardware properly sound/pci/hda/hda_tegra.c | 86 ++++++++----------------- sound/soc/tegra/tegra30_ahub.c | 113 +++++++++------------------------ sound/soc/tegra/tegra30_ahub.h | 6 +- 3 files changed, 59 insertions(+), 146 deletions(-) -- 2.29.2

Sound stutters with TC-Helicon GoXLR
by GitHub issues - opened 15 Jan '21

15 Jan '21

alsa-project/alsa-lib issue #113 was opened from Toniob: Hi, I bought a hardware mixer from TC-Helicon. I mainly use it under windows for streaming. But now, I'm trying to make it work under Linux, which I use for work. The hardware is seen as a multi-inputs multi-outputs soundcard under Linux. I use Debian unstable, Gnome (xwayland) and pulseaudio. It's an usb connected hardware (with its own power). The sound was stuttering every 3 or 4 seconds. It was plugged on a usb 3.0 port on the motherboard. But then, I bought a pci-express usb 3.0 card and I plugged the goxlr on it. The stutters are steal present but less often (I'd say on every 30 seconds). I've opened an issue on pulseaudio gitlab but it doesn't seem related to pulse as I've got the issue with alsa only : https://gitlab.freedesktop.org/pulseaudio/pulseaudio/-/issues/1093 . I know a person, met on the discord of tc-helicon, who has exactly the same symptoms with another distribution. Another fun fact is that the inputs do not stutter. I can record my mic plugged in the goxlr and it never stutters. Issue URL : https://github.com/alsa-project/alsa-lib/issues/113 Repository URL: https://github.com/alsa-project/alsa-lib
