[PATCH 0/8] Convert Mediatek ASoC codecs to use GPIO descriptors
by Linus Walleij 09 Oct '23

09 Oct '23

Convert over the Mediatek codecs to use GPIO descriptors. One few-liner affects gpiolib-of.h, I don't think there will be conflicts so I suggest that all of this can be merged through ASoC after review.

[PATCH 0/2] ASoC: codecs: fix widget name comparisons
by Krzysztof Kozlowski 09 Oct '23

09 Oct '23

Hi, Some codec drivers compare widget names with strcmp, ignoring the component name prefix. If prefix is used, the comparisons start failing. Add a helper to fix the issue. If the approach looks good, I will fix other codec drivers.

time to remove COPYING.GPL from alsa-plugins? (issue #45)
by Michael Wang 09 Oct '23

09 Oct '23

Hi Alsa-devs and Mr Iwai, Sorry for the spam, I am resending this in plain text mode this time. It seems the only thing in alsa-plugins that has a GPL license is rate/rate_samplerate.c, and that is due to the license of libsamplerate. But in 2016, libsamplerate dropped the commercial/GPL part of its license and was released with the 2-Clause BSD license. So I was wondering if the license for rate_samplerate.c can be updated to remove the GPL license, which means the COPYING.GPL file can also be removed from the alsa-plugins package? I have created issue #54 in github.com/alsa-project/alsa-plugins, but so far, no action. Should I submit a pull request?

[PATCH v2 1/2] ASoC: dt-bindings: fsl_rpmsg: List DAPM endpoints ignoring system suspend
by Chancel Liu 09 Oct '23

09 Oct '23

Add a property to list DAPM endpoints which mark paths between these endpoints should not be disabled when system enters in suspend state. LPA means low power audio case. On asymmetric multiprocessor, there are Cortex-A core and Cortex-M core, Linux is running on Cortex-A core, RTOS or other OS is running on Cortex-M core. The audio hardware devices can be controlled by Cortex-M. LPA can be explained as a mechanism that Cortex-A allocates a large buffer and fill audio data, then Cortex-A can enter into suspend for the purpose of power saving. Cortex-M continues to play the sound during suspend phase of Cortex-A. When the data in buffer is consumed, Cortex-M will trigger the Cortex-A to wakeup to fill data. LPA requires some audio paths still enabled when Cortex-A enters into suspend.
