[PATCH] ASoC: fsi: Stop using __raw_*() I/O accessors
by Geert Uytterhoeven 01 Dec '20

01 Dec '20

There is no reason to keep on using the __raw_{read,write}l() I/O accessors in Renesas ARM or SuperH driver code. Switch to using the plain {read,write}l() I/O accessors, to have a chance that this works on big-endian.

[PATCH 0/6] ASoC: mediatek: mt8192: support new machine rt1015p_rt5682
by Tzung-Bi Shih 01 Dec '20

01 Dec '20

The series supports new machines with rt1015p and rt5682. Reuses most of the code in mt8192-mt6359-rt1015-rt5682.c. The first 3 patches refactor the existing mt8192-mt6359-rt1015-rt5682.c. For easier to support newly added components later. The 4th patch fixes a typo in DT bindings document. The 5th patch proposes a new compatible string "mt8192_mt6359_rt1015p_rt5682" for machines with rt1015p and rt5682. The 6th patch reuses the existing machine driver to support machines with rt1015p and rt5682.

Mute LED not working on HP (Realtek ALC245)
by Soham Sen 01 Dec '20

01 Dec '20

Hello, I've been trying to debug the issue related to the microphone LED not working under Linux. I've confirmed that the LED works in windows. Seems like most HP laptops have this problem, and they are fixed by adding a model= parameter, however I've tried all HP mute LED related models on https://www.kernel.org/doc/html/latest/sound/hd-audio/models.html to no success. A very similar model to my laptop, running Intel HD Audio can be fixed by using model=hp-mute-led-mic3 but this didn't work on my laptop either. Can I get any help on how to further debug this issue? I tried searching for the documentation for this audio card, but wasn't able to find anything useful. Output of alsa-info.sh: http://alsa-project.org/db/?f=4173cebd458b6badbc21668461e9ba2e890333c2 Thanks, Soham Sen.

[PATCH 5.4 96/98] ASoC: Intel: Skylake: Await purge request ack on CNL
by Greg Kroah-Hartman 01 Dec '20

01 Dec '20

From: Cezary Rojewski <cezary.rojewski(a)intel.com> commit 7693cadac86548b30389a6e11d78c38db654f393 upstream. Each purge request is sent by driver after master core is powered up and unresetted but before it is unstalled. On unstall, ROM begins processing the request and initializing environment for FW load. Host should await ROM's ack before moving forward. Without doing so, ROM init poll may start too early and false timeouts can occur.
