[PATCH] kselftest/alsa: Increase kselftest timeout
by Nícolas F. R. A. Prado 16 Jun '23

16 Jun '23

The default timeout for kselftests is 45 seconds, but pcm-test can take longer than that to run depending on the number of PCMs present on a device. As a data point, running pcm-test on mt8192-asurada-spherion takes about 1m15s. Set the timeout to 10 minutes, which should give enough slack to run the test even on devices with many PCMs. Signed-off-by: Nícolas F. R. A.

[PATCH v2 00/65] clk: Make determine_rate mandatory for muxes
by Maxime Ripard 05 Apr '23

05 Apr '23

Hi, This is a follow-up to a previous series that was printing a warning when a mux has a set_parent implementation but is missing determine_rate(). The rationale is that set_parent() is very likely to be useful when changing the rate, but it's determine_rate() that takes the parenting decision. If we're missing it, then the current parent is always going to be used, and thus set_parent() will not be used. The only exception being a direct call to clk_set_parent(), but those are fairly rare compared to clk_set_rate(). Stephen then asked to promote the warning to an error, and to fix up all the muxes that are in that situation first. So here it is :) Let me know what you think, Maxime To: Michael Turquette <mturquette(a)baylibre.com> To: Stephen Boyd <sboyd(a)kernel.org> To: Andreas Färber <afaerber(a)suse.de> To: Manivannan

[PATCH v2] kselftest/alsa: Increase kselftest timeout
by Nícolas F. R. A. Prado 03 Apr '23

03 Apr '23

The default timeout for kselftests is 45 seconds, but that isn't enough time to run pcm-test when there are many PCMs on the device, nor for mixer-test when slower control buses and fancier CODECs are present. As data points, running pcm-test on mt8192-asurada-spherion takes about 1m15s, and mixer-test on rk3399-gru-kevin takes about 2m. Set the timeout to 4 minutes to allow both pcm-test and mixer-test to run to completion with some slack. Reviewed-by: Mark Brown <broonie(a)kernel.org> Signed-off-by: Nícolas F. R. A.

I wonder who is supposed to apply this patch. Either it should be split by file and go in via the respective maintainers, or it goes in via Greg's tree? I added Greg to To: for him to chime in.

[PATCH] ASoC: da7219: Fix pole orientation detection on OMTP headsets when playing music
by David Rau 09 Feb '23

09 Feb '23

The OMTP pin define headsets can be mis-detected as line out instead of OMTP, causing obvious issues with audio quality. This patch is to put increased resistances within the device at a suitable point. To solve this issue better, the new mechanism setup ground switches with conditional delay control and these allow for more stabile detection process to operate as intended. This conditional delay control will not impact the hardware process but use extra system resource. This commit improves control of ground switches in the AAD logic.

[PATCH][next] ASoC: uapi: Replace zero-length arrays with __DECLARE_FLEX_ARRAY() helper
by Gustavo A. R. Silva 03 Feb '23

03 Feb '23

Zero-length arrays are deprecated and we are moving towards adopting C99 flexible-array members, instead. So, replace zero-length arrays declarations in anonymous union with the new __DECLARE_FLEX_ARRAY() helper macro. This helper allows for flexible-array members in unions.

[PATCH] Sound: pci/hda: Add quirk for HP Envy x360 ey0xxx
by Fae 02 Feb '23

02 Feb '23

This patch fixes speaker output on the HP Envy x360 ey0xxx The mic/speaker mute LEDs are still non-functional but they aren't required for basic funtionality Also the quirk is labeled ALC287_FIXUP_CS35L41_I2C_2 however it does not only apply to ALC287 Its function is the generic cs35l41 fixup telling the driver that there's 2 i2c speakers. It isn't actually specific to ALC287 I did have a bit of luck getting the mic mute LED to work but it was to finicky to submit ( I used the ALC245_FIXUP_HP_GPIO_LED quirk ) I had no luck getting the speaker mute LED to work Signed-off-by: Fae <faenkhauser(a)gmail.com> --- sound/pci/hda/cs35l41_hda.c | 3 ++- sound/pci/hda/patch_realtek.c | 1 + 2 files changed, 3 insertions(+), 1 deletion(-) diff --git a/sound/pci/hda/cs35l41_hda.c b/sound/pci/hda/cs35l41_hda.c index 129bffb431c22..21d8c2de128ff 100644 --- a/sound/pci/hda/cs35l41_hda.c +++ b/sound/pci/hda/cs35l41_hda.c @@ -1156,7 +1156,8 @@ static int cs35l41_no_acpi_dsd(struct cs35l41_hda *cs35l41, struct device *physd hw_cfg->valid = true; put_device(physdev); - if (strncmp(hid, "CLSA0100", 8) == 0) { + if ((strncmp(hid, "CLSA0100", 8) == 0) || + (strncmp(hid, "CSC3551", 7) == 0)) { hw_cfg->bst_type = CS35L41_EXT_BOOST_NO_VSPK_SWITCH; } else if (strncmp(hid, "CLSA0101", 8) == 0) { hw_cfg->bst_type = CS35L41_EXT_BOOST; diff --git a/sound/pci/hda/patch_realtek.c b/sound/pci/hda/patch_realtek.c index 8a57636f622e9..e7053cbc6bb6e 100644 --- a/sound/pci/hda/patch_realtek.c +++ b/sound/pci/hda/patch_realtek.c @@ -9179,6 +9179,7 @@ static const struct snd_pci_quirk alc269_fixup_tbl[] = { SND_PCI_QUIRK(0x103c, 0x83b9, "HP Spectre x360", ALC269_FIXUP_HP_MUTE_LED_MIC3), SND_PCI_QUIRK(0x103c, 0x841c, "HP Pavilion 15-CK0xx", ALC269_FIXUP_HP_MUTE_LED_MIC3), SND_PCI_QUIRK(0x103c, 0x8497, "HP Envy x360", ALC269_FIXUP_HP_MUTE_LED_MIC3), + SND_PCI_QUIRK(0x103c, 0x8a31, "HP ENVY x360 2-in-1 Laptop 15-ey0xxx", ALC287_FIXUP_CS35L41_I2C_2), SND_PCI_QUIRK(0x103c, 0x84da, "HP OMEN dc0019-ur", ALC295_FIXUP_HP_OMEN), SND_PCI_QUIRK(0x103c, 0x84e7, "HP Pavilion 15", ALC269_FIXUP_HP_MUTE_LED_MIC3), SND_PCI_QUIRK(0x103c, 0x8519, "HP Spectre x360 15-df0xxx", ALC285_FIXUP_HP_SPECTRE_X360), -- 2.37.1
