Taken from the ChromeOS sources, this configuration should apply to all Nyan boards from Google, so far HP Chromebook 14 (nyan-blaze) and Acer Chromebook 13 (nyan-big).
How does user-space correlate the files added here:
src/conf/ucm/GoogleNyan/GoogleNyan.conf | 5 ++ src/conf/ucm/GoogleNyan/HiFi.conf | 83 +++++++++++++++++++++++++++++++++ src/conf/ucm/GoogleNyan/Makefile.am | 4 ++
... with the (DT-provided) ASoC card name, or DT compatible value:
sound { compatible = "nvidia,tegra-audio-max98090-nyan-big", "nvidia,tegra-audio-max98090"; nvidia,model = "Acer Chromebook 13";
I would have expected either the file/directory names in this repo to match the ASoC card name that the kernel exposes (derived from the model string above), or that the files here contain some kind of indexable string that contains the kernel's ASoC card name. Is that not how the UCM repo usually works?
Otherwise, generic distro UCM init scripts aren't possible; UCM setup scripts would need a huge table mapping ASoC card name to UCM repo file/directory name, which doesn't seem scalable.
