[alsa-devel] Headset button mapping in the kernel

Hello ALSA Devs,

I am looking to get some feedback/ideas on a possible change to headset button mapping. Locally we are carrying patches that implement the mappings in the machine driver (which we understand you do not want upstream.) We are looking to see if we can add a new API (something like a sysfs path potentially) to have userspace pass in the mapping, if it chooses to, so the mapping can still be done in the kernel. That way we can carry just the config locally and remove some of the kernel patches we are carrying locally. Thanks.
