[v3 0/2] ASoC: mediatek: mt8192: support rt1015p_rt5682s
by Jiaxin Yu 11 Mar '22

11 Mar '22

From: Jiaxin Yu <jiaxin.yu(a)mediatek.corp-partner.google.com> The series reuses mt8192-mt6359-rt10150rt5682.c for supporting machine driver with rt1015p speaker amplifier and rt5682s headset codec. Changes from v2: - fix build warnings such as "data argument not used by format string" Changes from v1: - uses the snd_soc_of_get_dai_link_codecs to complete the configuration of dai_link's codecs - uses definitions to simplifies card name and compatible name Jiaxin Yu (2): ASoC: dt-bindings: mt8192-mt6359: add new compatible for using rt1015p and rt5682 ASoC: mediatek: mt8192: support rt1015p_rt5682s .../sound/mt8192-mt6359-rt1015-rt5682.yaml | 1 + sound/soc/mediatek/Kconfig | 1 + .../mt8192/mt8192-mt6359-rt1015-rt5682.c | 204 +++++++++++------- 3 files changed, 129 insertions(+), 77 deletions(-) -- 2.18.0

jack: implement pcm operation sw_params
by GitHub pull_request - edited 11 Mar '22

11 Mar '22

alsa-project/alsa-plugins pull request #43 was edited from aditpape: Alsa-lib commit #88e4ae27 introduced a dynamic recalculation of the avail_min value on the underlaying slave devices. This updated avail_min value is not reaching the alsa-jack plugin due to lack of the sw_params operation. This patch adds this missing operation to correctly apply an updated avail_min setting during runtime.

[RFC PATCH 0/3] Flexible codec clock configuration
by Sameer Pujar 11 Mar '22

11 Mar '22

Typically the codec drivers require setting up of Sysclk. Sometimes presence of internal PLL can provide more options of Sysclk configuration. Presently ASoC provides callbacks set_sysclk() and set_pll() in such cases. However it comes with following limitations considering generic machine drivers (simple-card or audio-graph-card): 1. The Sysclk source needs to be passed to set_sysclk() callback. Presently simple-card or audio-graph-card card rely on default source value (which is 0). If any other source needs to be used, it is currently not possible. 2. The same would be true for codec PLL configuration as well, though simple-card or audio-graph-card don't have support yet for the PLL configuration. Earlier attempt[0] to address above was not felt suitable. The suggestion was to use standard clock based bindings instead. This RFC series takes RT5659 as a reference and exposes clock relationships via DT. **This is not in the final shape yet**, but I wanted to get some valuable feedback to understand if the idea is right. If this appears fine, this can be extended to other codecs (wherever necessary). This does not completely remove the need of set_sysclk() callback because the clock requirement (MCLK * fs) would come from the machine driver. But machine driver need not worry about Sysclk source. It would be internally managed by Codec via DT clock relationships.

[PATCH v2] ASoC: tas5805m: fix pdn polarity
by John Keeping 11 Mar '22

11 Mar '22

The binding defines the GPIO as "pdn-gpios" so when the GPIO is active the expectation is that the power down signal is asserted and this is how all other drivers using this GPIO name interpret the value. But the tas5805m driver inverts the sense from the normal expectation so when the powerdown GPIO is logically asserted the chip is running. This is a new driver that is not yet in a released kernel and has no in-tree users of the binding so fix the sense of the GPIO so that logically asserted means that the device is powered down. Rename the variable to match so that the compiler will catch any places that should have been updated but have been missed.

Hi  Takashi, if adjusting the mixer element or replugging the headset, the headphone would be unmuted. But most users hope that the default state is unmuted.

Presence of "default" device name crashes unity3d games

alsa-project/alsa-lib issue #214 was opened from the3dfxdude: In a recent Slackware 15.0 distro release, the alsa-lib version is now 1.2.5.1. This causes a crash in Kerbal Space Program similar to issue #27. A change was made to close issue #27 in alsa-lib 1.2.3. That change did not correct the crash however in 1.2.3 or 1.2.5.1 in my case.

You may remove the default device name by editing src/conf/pcm/default.conf and adding under the hint section "omit_noargs true". Unity must be parsing the device name, and with certain device names, if there is no ':' doing something bad, as there is a pattern here on what it trips on. I have no idea how to get them to correct this, so opening the issue here at least for the record if anyone else has an issue with this. Also, I am not sure what triggers "default" to show. I did a survey and 3 out of 5 of my slackware 15.0 systems have it. And 2 do not. Does this have something to do with parsing the system alsa config and the available sound devices in the system? I don't define any asound.conf for any of these, so these are almost 100% stock slackware systems, there should otherwise be no difference.

[PATCH v3 00/16] Support external boost at CS35l41 ASoC driver
by Lucas Tanure 10 Mar '22

10 Mar '22

Move the support for CS35L41 external boost to its shared library for ASoC use. This move resulted in cs35l41_hda_reg_sequence being removed, and its steps were broken down into regmap writes or functions from the library. And hardware configuration struct was unified for its use in the shared lib. While at it, some minor bugs were found and fixed it. v3 changelog: - Remove patches already accepted - Improved logic in documentation patch - Documentation patch goes before its code - Fixed missing Signed-off-by - Fixed subject for HDA patches v2 changelog: - Instead of removing the log, playback actions will log the last regmap access. - Documentation patch with the correct subject line and fixed bug reported by Rob Herring on the provided example.
