[PATCH] dt-bindings: Move fixed string node names under 'properties'
by Rob Herring 23 Nov '22

23 Nov '22

Fixed string node names should be under 'properties' rather than 'patternProperties'. Additionally, without beginning and end of line anchors, any prefix or suffix is allowed on the specified node name. These cases don't appear to want a prefix or suffix, so move them under 'properties'. In some cases, the diff turns out to look like we're moving some patterns rather than the fixed string properties.

(E)AC3, DTS, MPEG-H support in tinycompress and the kernel uapi?
by GitHub issues - opened 22 Nov '22

22 Nov '22

alsa-project/tinycompress issue #20 was opened from dv1: Have there been discussions about adding support for (E)AC3, DTS, and MPEG-H? These days, 3D Audio is a use case where the Compress-Offload API is useful. It therefore would make sense to add support for these formats. I'm talking about direct support, not through IEC958 / IEC61937 payloading. I know that some HW vendors add their own custom changes to tinycompress to support these formats, so why not add these to upstream?
