[alsa-devel] Hiding some of the controls defined in codec driver from machine driver context

Hello,

Is it possible to 'hide' some of the controls of the codec in the machine driver? The codec I'm using exposes many advanced controls which are useful for board developers, but not for the end user, so I'd like to define my own 'simplified' controls, and take care of board specific logic internally in the machine driver.

I found this old discussion on the topic: https://www.spinics.net/lists/alsa-devel/msg36386.html - I'm targeting kernel 4.14, maybe there's already some means to achieve this?

Thank you! Giedrius.
